Issei Hyodo

Relations.

Xenovia: Xenovia and Issei first met and she didn't care for him too much. Issei initially disliked her due to his tendency to call Asia a witch and wanted to kill her, but after vol. 3, he greatly apologizes and became a Devil after learning of God's death. She then decides that she wants to have strong children and chooses Issei to be her partner. She is completely oblivious to sexual situations due to being raised in the Church, and will try to have sex anywhere with Issei, even going so far as to bring condoms to school so they could "practice". She subsequently develops strong feelings for him due to Issei being quite protective of her, something she greatly enjoys and thus falls madly in love with him. She doesn't get jealous when girls are around him, often just letting him, though when one of the girls tries to have sex with him, she gets jealous and tries to take him away. Issei is willing to protect her as well as the other girls, and he loves the idea of ​​having children with her. She is the sixth in Issei's harem.

Relations.

•Kiba Yūto: Yūto is a Knight of the Gremory clan and is Issei's self-proclaimed best friend. Issei initially disliked Yuuto because he always attracted all the girls' attention with his good looks, but Issei grew to see Yūto as a good friend. They both wished to become stronger so they could protect the Gremory clan. Issei and Yūto have a good friendship and are willing to protect each other from danger. When Issei died, Yūto felt a lot of sadness, anger, and frustration, taking his anger out on Siegfried. When he learned that Issei's spirit was still alive, he gained hope. •Irina Shidō: Irina and Issei had been childhood friends and reunited in vol. 3, though Issei was shocked to see her because as kids he thought she was a boy. Issei likes her a lot and has perverted thoughts about her just like he did with the other girls. She had a crush on Issei since they were little, but was disappointed to see that he had become a Devil and a pervert, but nevertheless, she still loved him. She wants to make love to Issei and have his children just like Xenovia, ostensibly to strengthen the forces of Heaven. She loves Issei very much, but is having trouble in the harem because if she thinks or does something wrong, she starts to "fall". However, it is suggested that she is willing to fall for Issei's sake. Issei wants to give her children as well as protect her just like he did with the other girls. She is the fifth in Issei's harem.

Relations.

•Koneko Tojo: Koneko hated Issei because of his lustful mind and mannerisms, but grew to love him after seeing how he never gives up and is willing to do anything for anyone. She started to have feelings for him in Volume 5 after he helped her overcome her fear of her Senjutsu due to Issei telling her that he would stop her if she got out of control. After that she started to sit anywhere as long as it was on Issei's lap, and started seducing him like all the other women in the harem. She often gets jealous like the others if another girl is with him or is hogging him. Their love grew and grew until it reached its climax in Volume 11 where she entered the mating season and chose him as her mate, but was stopped by Kuroka. Later in the same volume, she proposed to Issei to be his girlfriend, which Issei accepts under the condition that she must grow more. She wants to be more than just a girlfriend to Issei because she chose him to be her soul mate. Her relationship with him is very serious, but it will have to wait to develop more because her body is small and it would be a danger for her to have children at this time. When Issei died, she cried a lot along with Ravel and was also very happy to hear that his spirit was still alive. She is the fourth in Issei's harem.

Relations.

•Akeno Himejima: When Akeno first met Issei, she thought of him as a kohai that she could spoil and flirt with, but as time went on she started to see that Issei was very protective and began to fall for him. She truly fell in love with him in vol. 7 after he helped her unleash her Holy Lightning ability. She loves him dearly and isn't afraid to get into fights with the other girls when she gets jealous. She is very fine with being third in his harem after Rias and Asia, and likes the idea of ​​an adventure. Issei cares a lot for her, and is willing to risk his life for her. She was completely heartbroken and cried a lot when she found out that Issei had died, and was extremely depressed by the news. She later learned that Issei's spirit is alive and well and his power was enhanced by Issei's bracelet, giving him access to his Fallen Angel form, where his powers increased drastically. Issei confesses to Baraqiel that he is in love with her and that he will take her as his wife, to which she becomes very happy, wanting to give him their first child. She is the third in Issei's harem.

Relations.

•Asia Argento: Asia first met Issei when he was being his usual lecherous self, going so far as to call her a blonde bishōjo. They meet again during a mission where he fought Freed Sellzen, whom he was working with after leaving the Church. Whom she was working with after being abandoned by the Church. After that incident, she left Freed and became immediately fascinated with Issei due to him wanting to protect her. She was kidnapped by Raynare and later died after she took her Sacred Gear. Issei avenged her and, with Rias's help, brought her back to life as a Devil, and she automatically fell in love with him. Though Asia doesn't seem to realize that Issei does indeed have feelings for her as well. Following the incident, Issei feels he must always protect her and doesn't want to lose her again. He often has lustful thoughts about her and loves her very much, but tries to block these thoughts out, thinking that he must protect her from everyone, including himself, and tries to think of her as a little sister. She often gets teary-eyed when other girls flirt with him. When Issei died, she, along with the others, lost her will to fight, she regained her hope after hearing that his spirit was still alive. She is apparently the second in Issei's harem, after Rias. After Issei became a High-Class Devil, she became his bishop.

Relations

•Rias Gremory: She is the one who reincarnates Issei and is the love of his life. When she first summoned him, she treated him as a "special" case, knowing that he had great potential, but as time passed, she found her softer side and began to fall in love. She and Issei had their first kiss after the latter's duel with Riser. She often gets jealous when other girls flirt with him or try to tempt him. She loves him very much and is willing to do anything for him. In response, Issei will do anything to protect her, as he loves her as much as she loves him. Once, she even tried to have sex with him to get out of an arranged marriage. To add to this, Issei constantly wakes up to her naked sleeping next to him. For this reason, she says she has no problem letting Issei see her naked and even allows him to touch her breasts from time to time, she always says that she has no problem as long as it's him. Issei gains permission from Rias's mother to start a harem to keep the girls happy. She was completely heartbroken by the news of Issei's death, but gained a great deal of hope when she learned that his spirit lives on through his Evil Pieces. It also seems that whenever Issei sees or touches her breasts, he gains a tremendous power boost, helping him achieve his Balance Break and the Final Move Trident, or even restore his energy. This, however, has resulted in her earning derogatory nicknames such as the "Switch Princess" (Bikō) and the "Crimson Breast Princess" (Azazel). She is the first in Issei's harem, and eventually, Rias and Issei ended up as a couple.

Weaknesses and Vulnerabilities.

As the possessor of a Dragon-type Sacred Gear, in addition to the common vulnerabilities of Devils such as objects of Light and Holiness, Issei is vulnerable to Dragon-slaying elements such as the Dragon Slayer swords like Gram and Ascalon, and the poison curse of Samael who is known as the supreme dragon slayer. Ddraig has warned that now that Issei's flesh is dragon it is true that he may be even more vulnerable to these dragon-slaying effects.

Attacks.

•Boosted Gear: Issei possesses unimaginable power as he has the legendary scarlet dragon encased in his left arm. The dragon's power grows stronger as its user offers something to the dragon, his Boosted Gear is so strong that it even becomes like armor, but has a limited time based on how much of your body is offered to the dragon. The Boosted Gear also has the power to absorb energy and use it to his advantage. Issei has also invented a number of attacks that suit his lustful nature. During training in preparation for Rias' Rating Game against Riser and his maids, he invented Dress Break, which allows him to strip a woman of all her clothing after coming into contact with them by concentrating his magical energy into the clothing. He has also invented the attack , which gives him the ability to speak to the breasts of all women, which he developed during his training with Tannin when he was unable to see Rias for almost a month. It is a very useful technique as it helps Issei learn his opponents' plans and strategies by asking their breasts, however, due to complaints from female combatants, this technique, along with Dress Break, were banned from the Rating Games. Due to his perverted nature and overwhelming sex drive, he has been known as someone who can defeat any female opponent with his special techniques, and women who know him are afraid to fight him because of this. In fact, he achieved his Balance Breaker just by squeezing Rias's breasts, and gained the Legal Move Trident as well by using this method. Due to his training with Tannin, Issei has gained minor experience surviving while in mountainous regions. He has also learned how to hide his presence from people.

Powers and Abilities.

While defending himself against the human members of the Hero Faction, Issei develops mini-magic dragon missiles, which are tuned to knock out normal humans.

Powers and Abilities.

Issei displayed no special powers or abilities. Upon becoming a Devil, however, he has enhanced physical abilities (being able to pedal his bike extremely fast in the anime, for example) and heightened senses. Additionally, as a pawn, he has the ability to use promotion whenever he is in enemy territory, becoming any piece except the King Piece. Issei has since had to modify his Evil Pieces to allow him to promote at any time, and to switch between promotions as needed. Issei's Sacred Gear is the Boosted Gear, one of the 13 Longinus where one of the Heavenly Dragons, Sekiryuutei Ddraig, the Red Dragon Emperor, resides. It is said to have the power to kill Maou and Gods when fully mastered. The abilities of his Sacred Gear are to double its power every 10 seconds without limit, and its sub-ability is to be able to transfer its multiplied power to a being or object, making it great in terms of support. Issei can also fire a beam of energy by concentrating his magical powers, which he calls the "Dragon Shoot". After his fight with Sirzechs, inspired by Sirzechs' use of his Power of Destruction, Issei begins to work on how to redirect his Dragon Shot by moving it in different directions, first using it in Volume 12 against the Jabberwocky. Issei placed one of the Jabberwocky's Divine Dividing Jewels into his Scale Mail Armor, creating the Dividing Gear that allows him to use Albion's splitting powers. This ability, however, reduces Issei's lifespan and was thus forbidden by Azazel.

History.

The fight, however, ended without a clear outcome, Crom Cruach appeared and ordered Grendel to retreat. Vali then appeared as both Issei and Vali vowed to join forces to face the stronger Evil Dragon. Issei in his Crimson Cardinal Queen form was able to deal minor damage to Crom Cruach using Crimson Blaster combined with Ascalon's Dragon Slayder ability. The fight was stopped by Crom Cruach since he was told to only entertain them for ten minutes. Issei later fought against the mass-produced Evil Dragons that were rampaging in Carmilla's castle city and was able to easily defeat them, until he encountered Euclid Lucifugus. He then fought Euclid who used a replica of the Boosted Gear. He was overwhelmed by Euclid, but was able to turn the tables when he used his newfound power which allows him to create small white dragons that he can "split" and "reflect". The fight was stopped when Rizevim and Lilith arrived and told Euclid that it was time to retreat. After returning from Romania, Issei participated in the meeting for the formation of the DxD Group and told Ravel that he wants Le Fay to make the Mage/Demon contract.

History.

While Issei and Ravel are selecting the Magi to make a pact with, Akeno, Sona, and Bennia entered their room to talk about what the Sitri Group and the Gremory Group would do while Rias and Yuuto are in Romania. They made their discussion at the underground pool when Kuroka and Le Fay arrived and were surprised when Kuroka mentioned that they fought against the evil dragon, Aži Dahāka. Griselda Quarta, Dulio Gesualdo, and Tobio Ikuse later arrived and asked Issei if it is okay for them to help train the group in which Issei happily agreed. Issei, along with the Occult Club members, Bennia, and Loup Garou went to Romania to help Rias and Yuuto who were locked in Tepes Castle, reuniting with the two when they arrived at the castle. They were then taken to the throne room to meet the new "king", Valerie Tepes and the new mayor, Marius Tepes as the group became angered by an action of Marius and the latter's claim that he could do so without fearing for his life due to his bodyguard, the evil dragon Crom Cruach. After the meeting was over, Issei and the others met an old man wearing a Lucifer costume who was shocked to learn that the man was Vali's grandfather, Rizevim Livan Lucifer and denied Rizevim's proposal to join his group. Issei then participated in the attempt to stop Valerie's extraction of the Longinus, the Holy Grail, and save her. Meeting Grendel again, Issei and his friends team up to fight Grendel in order to buy time for Rias to use her new move, in which they successfully dealt serious damage to Grendel with their combined efforts.

History.

In the end, Issei starts calling him Milicas instead of Milicas-sama. Later, Issei obtains a familiar, which is the Living Norse Vessel, Skíðblaðnir which was given to him by Surtr the Second. Issei meets with the Director of the Magus Council, Mephisto Pheles, regarding the pact between Rias Gremory's Clan and the Magus Association. He later attended the negotiation with the Vampires that were led by Elmenhilde Galnstein who wanted Gasper to join her clan, the Carmilla Faction. He was completely ignored when he asked her a question, due to her status as an official. Several days later, while attending his class, Issei was attacked by three Stray Mages who distracted him so they could kidnap the first-year students of the Occult Research Club. He, along with the other members of the Occult Research Club and the Student Council then go to battle them, then easily eliminate the Stray Mages and the Khaos Brigade Mages before a voice called for Issei, Akeno, Xenovia, Asia, Irina, Rosswiesse, Saji, and Sona to meet them. The group was sent to a "factory" built in the dimensional rift that was used to create artificial Phoenix Tears using clones of the Phenex Clan. After some talk with the supposed leader, he summoned Grendel one of the previously thought dead Evil Dragons and Issei was forced into a battle, but was overpowered throughout the fight until he used Ascalon's Dragon Slayer abilities to turn the tides. It was then that the head of the Mages, Lucifuge Euclid, Grayfia's younger brother, calls for Grendel to retreat as he reveals himself to Issei and the others.

History.

Issei's original body is destroyed due to Samael's curse, but he gains another body through the help of the Great Red and Ophis. He returns and successfully saves the children of the Underworld who were taken hostage by Jeanne and Heracles, easily defeating them. He has his third encounter with Cao Cao, but is easily defeated by the latter, despite Rias using her ability to recharge Issei's power, until Issei used a Gogmagog bullet that had Samael's blood in it on the Medusa Eye that Cao Cao was using, reversing the tides. In order to turn the tide of the battle, Cao Cao attempts to activate the Truth Idea, but it fails due to the effects depending on the God's will within the Holy Spear and will differ depending on which will is chosen. The True Longinus has chosen the desire in Issei's heart over Cao Cao's ambition, thus he is defeated. At the end of Volume 12, Issei is officially promoted to a Middle-Class Devil, along with Akeno and Yūto. Afterwards, Rias and Issei plan to go on a date as they promised before, as the rest of the Occult Research Club members (including the boys, much to Issei's distress) decide to go on dates with him as well. Milicas heads to the Hyoudou residence and temporarily stays with them. Later, she has a mock battle royale against Issei, Kiba, and Gasper. Despite losing to Milicas, Issei notes that her power is overwhelmingly extraordinary and her talent is dangerously close to that of Vali Lucifer. Later, when Sirzech asked her if she liked the Red Satan or the Oppai Dragon more, Milicas chose the latter, causing Sirzech to feel slightly sad, which only increased when he saw that the two were getting along well.

History.

Both Issei and the rest of Team Gremory are shocked to see Ophis, accompanied by Le Fay Pendragon and Kuroka, arriving at their house, something set up by Azazel after Ophis claims to want to observe Issei. Afterwards, Issei, Akeno, and Yūto travel to the Glasya-Labolas Territory to take the promotion exam to become Middle-Class Devils. While the group is resting after the test, they are ambushed by Cao Cao and Georg who arrived to steal Ophis's powers. The battle ends with Team Gremory and Vali losing to Cao Cao and Ophis's powers being stolen. Both teams are then attacked by a legion of Grim Reapers and Siegfried. They eventually overcame the situation by having Issei use Rias's breasts to replenish Issei's Magic and successfully forced the enemy forces back until Shalba appeared with a kidnapped Leonardo, forcing him to activate his Balance Breaker which creates 13 gigantic monsters to destroy the Underworld and kidnap Ophis. Issei went to rescue the kidnapped Ophis from Shalba who escaped into a crumbling dimension field. Issei eventually caught up to Shalba and the two had one last fight before Issei killed Shalba. During the fight, however, Shalba manages to shoot Issei with an arrow laced with Samael's blood, resulting in Issei's death.

History.

After finishing another Oppai Dragon campaign, Issei and Rias see Rias's mother, Venelana, who congratulated them on their hard work before scolding Rias for her lack of progress with Issei. Rias then attempts to seduce Issei by attempting to have sex with him in the Hyōdō residence's sauna room. Issei, however, misunderstands and calls Rias "Buchō", causing him to become extremely sad and angry, then asks her what she means to him. During Rias's Rating Game against Sairaorg Bael, Issei fought Sairaorg's bishop, Coriana Andrealphus, and his queen, Kuisha Abaddon, defeating both before facing Sairaorg and his pawn, Regulus, in the final match with Rias. During the match, Issei was doing well against Sairaorg until Sairaorg fused with Regulus to use his Balance Breaker, overwhelming Issei. Issei, however, was able to turn the tide by accessing the True Queen, achieving the Cardinal Crimson Promotion which combines the power of the Rook, Knight, and Bishop into his Balance Breaker Armor as it changes from red to crimson. Using his newly acquired powers, Issei manages to fight on par with Sairaorg, successfully defeating him in a fistfight after Sairaorg lost consciousness. After his victory, Issei can no longer hold back his feelings for Rias and confesses to her, calling her by name for the first time. She accepts his feelings with tears of joy and the two officially become a couple, though it seems that none of the other girls (Asia, Akeno, Koneko, Xenovia, Irina, and Ravel) have given up on Issei.

History.

Issei and the rest of the second-year students go to Kyoto for a school trip. While on the train to Kyoto, Issei enters the depths of the Boosted Gear where he is held by one of the last remaining Boosted Gear wielders who provides him with a box that unlocks his potential and the possibilities of the Boosted Gear. During the trip, Issei was attacked by several Yōkai led by Kunō, who believed that he was responsible for the capture of her mother, Yasaka, the leader of the Yōkai. While they manage to clear up the misunderstanding, Issei and his friends soon face the true culprits in capturing Yasaka: the Hero Faction led by Cao Cao. While the first fight was interrupted by the interference of Le Fay Pendragon and Gogmagog of Vali's team, Issei and his friends are forced to face off against the Hero Faction once more in order to rescue Yasaka from them. During the fight, after seeing one after another of his friends being defeated, Issei curses his own lack of power but this time, with the advice of Belzard and Elsha, Issei successfully attains the Illegal Move Trident, due to his desire to protect his friends and Rias's breasts, allowing him to change into the Scale Mail through the Promotion. With his newfound power, Issei manages to temporarily overwhelm the entire Hero Faction before succumbing to the exhaustion caused by the Illegal Move Trident. The team, however, is rescued by the sudden appearance of Sun Wukong, who holds off the Hero Faction and through the use of his Senjutsu revitalizes Issei, allowing him to use another attack that landed right in Cao Cao's eye. After returning from Kyoto, the team was being scolded by Rias for not calling her to help them when Azazel told the group that Ravel had transferred to Kouh Academy, much to the dismay of the Occult Research Club girls.

History

The two teams eventually decided to work together to defeat Loki and Fenrir, seeking the advice of the Dragon King, Midgardsormr, on how to defeat Loki and Fenrir. During the final battle against Loki, Issei wielded a replica of Mjolnir, the hammer used by the Norse god Thor. Though initially completely unable to use Mjolnir, Issei gains the ability to use it after helping Akeno reveal her true feelings and make peace with her father through the aid of the Breast Fairy, thus along with Baraqiel's Holy Lightning, Akeno and Issei managed to defeat Loki. Issei and Rias go to the Underworld, where they undergo an engagement ceremony at the Connection Ruins. Issei, however, is unaware of the purpose of the ceremony. Throughout the ceremony, Issei and Rias undergo the four trials set by the "Satan Rangers". In the first test, Issei and Rias had to dance; in the second test, Issei and Rias were tested on table manners; and in the third test, Issei and Rias were tested on knowledge of the Gremory clan's history and general knowledge of the Underworld, all of which they successfully passed before moving on to the final test. In the final test, Issei was forced to fight Sirzechs/Satan Red and was completely overwhelmed by the latter until Grayfia advised them that they could use Rias's breasts as a power-up allowing Issei to use a Final Dragon Shot but they still lost after Sirzech repelled the attack and as they retreated Issei lost consciousness. After the ceremony, Ajuka Beelzebub, one of the Four Satans and the original creator of the Evil Pieces system, remodeled Issei's pieces to fit Ddraig's powers.

The Gremory Team then went to defeat Diodora and his minions and rescue Asia until the sudden appearance of Shalba Beelzebub who sends Asia into the dimensional rift. This act caused Issei to activate the Boosted Gear's Juggernaut Drive, due to the negative feelings that appear after Asia's apparent "death" and causes him to go berserk.

Waking up in his room and being informed of Rias's defeat by Grayfia, Issei becomes frustrated and blames himself for his weakness, only receiving a piece of paper from Grayfia with a magic circle engraved on it. Arriving at the engagement party, Rias's brother and Demon Lord Sirzechs Lucifer reveals that he created this event as entertainment for Rias's engagement party, allowing Issei to battle one-on-one against Raiser betting on Rias's engagement, and won through the strategy he had formulated beforehand.

History.

However, after learning that he can one day have his own servants, Issei declares his dream of becoming king of his own harem. Later, he meets Asia Argento, a nun, and quickly befriends her. He soon learns that she also possesses a Sacred Gear after she used it to heal a child. He then guides her to her church, where upon approaching, he gets strange chills throughout his body, forcing him to stop (Rias explains that Devils are not allowed to go near churches as they risk being killed by the Angels' Light Spears). During his first battle with the Stray Devil Viser, he learns from Rias about Yūto, Koneko, and Akeno's traits as Knight, Rook, and Queen respectively, and later learns, much to his disappointment, that he is a Pawn. The following night, Issei goes to meet with a client, only to find that upon arriving at the client's house, he was killed by Freed Sellzen, a stray exorcist. He is being overpowered by the mad priest until Asia intervenes, begging Freed to let Issei go but is beaten up by him, angering Issei who fights Freed once more but is stopped by the rest of the Occult Instigation Club who intervene and take Issei back, leaving Asia behind. Fortunately, Issei eventually joins Asia again at a nearby park the next day, and the two spend the entire day together, which ends with the sudden appearance of Raynare who takes Asia back, leaving an injured and overwhelmed Issei despite the latter having used his Sacred Gear.

History.

Issei is the only child in his family. Not much is shown of his past, except the fact that he is childhood friends with Irina Shidō. At some point during his childhood, Issei met an old man who told him and other children stories about breasts, which eventually led to Issei's fascination with them, and his perverted tendencies. He attends the same middle school as Matsuda and Motohama and the three started attending Kuoh Academy a year prior to the story, and have become known as the Perverted Trio to virtually the entire school. After being killed by Raynare and revived by being reincarnated by Rias, Issei discovers that he possesses the Boosted Gear one of the 13 Longinus where the master of the Sekiryuutei Ddraig is sealed, one of the Two Celestial Dragons despite this he is a very weak Demon who was called the weakest Sekiryuutei, so through his effort, training and battles against very powerful beings he begins to improve himself until he becomes one of the strongest characters. When Yūma Amano asks him to go out with her on a date. However, at the end of the date, Yūma suddenly kills him, revealing herself to be a fallen angel in the process. However, in his last moments, Rias Gremory saves his life by reincarnating him into a demon. The next day, after noticing some strange changes in his body, he is attacked by the fallen angel Dohnaseek, who leaves him seriously injured until Rias arrives and saves him once again. He is introduced to the other members of the Occult Research Club: Akeno Himejima, Koneko Tojo, and Kiba Yuuto, and soon learns that all of them, including Rias, are Devils. He soon learns, to his surprise, that he is a Devil as well.

Personality.

Despite being a pervert and having gained some notoriety for being one of the members of the Kouh Academy Perverted Trio, he has gained the attraction of many girls around him: Rias, Asia, Akeno, Koneko, Xenovia, Irina, and Ravel. This is due to his kindness, wanting to protect and help those important to him despite nearly dying at the hands of his opponents. He is also unaware that the girls around him had crushes on him, often believing that they were simply teasing him without taking his feelings seriously. Even Rias's familiars request that he use the same names with them as Rias uses (father, mother, brother, etc.) and many other mentions of engaged activities, but he does not seem to understand them. Because of this, he does not understand anything unless it relates to breasts or lewd things, which cannot be understood and is considered an idiot. Issei may be a lecherous pervert, but he will never take advantage of any of the girls, as evidenced when Koneko enters her heat phase, he cares a lot for his partner's well-being before taking advantage of her situation. After his murder by Raynare, Issei was afraid to admit his feelings for the girls, as he thought it would make them turn against him. He acknowledged that this would never happen, but it still caused him trauma. However, in Volume 10, that trauma is finally overcome thanks to the help of Asia, Akeno, Koneko, Xenovia, Irina, and Ravel who make him reflect and realize their feelings towards him and make him realize Rias's feelings for him. During the Battle against Sairaorg Bael in the Rating Game, Issei confesses his love for Rias in the Rating Game that was seen by the entire Underworld and the leaders of all the Factions; from that moment on, Issei began his love relationship with Rias and understood that all the Girls are in love with him.

Appearance.

Issei is a young man in his teenage years with an average build, short brown hair with several bangs that partially cover his eyebrows and two hair extensions that hang parallel to the back of his neck, and brown eyes. After his training with Tannin, he obtained a more muscular and toned build. While he has worn various outfits throughout the series, his most commonly worn outfit is the Kouh Academy uniform, which consists of a jacket (most commonly black, though in other media it is shown to have a purple or gray tint, with white accents) over a long-sleeved white shirt with black highlights and a black bow at the collar, matching black pants, and brown dress shoes. However, Issei's uniform is different in that he wears a red T-shirt under his shirt and jacket, and wears white and blue sneakers instead of dress shoes. He wears both the summer and winter styles depending on the school calendar he is in. Issei's left arm transformed into a dragon as a result of having signed a pact with the dragon Ddraig to gain power to defeat Raiser Phoenix. In order to give him a human appearance, Rias or Akeno performed a ritual in which the dragon power is extracted from him, allowing her to appear human for a few days. Issei's body was destroyed, in Volume 12 With the powers of Ddraig, Ophis, and Great-Red's flesh and blood, he made another Dragon body in a humanoid form. Thanks to this new body, Issei can freely transform any part of his body into a Dragon.
