Right Master

Appearance Due to the nature of Tengen's role in the jujutsu world, most people have no idea what they look like. Only those granted permission have seen that Tengen does not quite possess the appearance of a typical human being. Tengen has four eyes with a cylinder-shaped head that features no hair at all, but they do possess a bipedal humanoid body. They wear a simple light-colored robe. As stated by Tengen, due to Toji Fushiguro killing the previous Star Plasma Vessel 12 years ago and preventing Tengen from merging with her, Tengen's current appearance is the result of them having continued to "evolve" past their humanity. Tengen originally possessed a much more human appearance.

Personality Tengen appears to be a well-mannered, straightforward, and knowledgeable individual with humanity's best interest in mind. They don't seem to mind awkward questions about their experience and is more than happy to help normal jujutsu sorcerers provided the right situation. Tengen was willing to do all they could to help Yuji and the others stop Kenjaku, but in return asked that two members of his team remain behind to protect them as well. They were stern about this point, but only because Tengen's own safety is the key to humanity's survival. As shown from the previous mission to protect their Star Plasma Vessel, Tengen also has a softer and kinder side to themselves. This is seen where they ordered Satoru Gojo and Suguru Geto to respect and accommodate Riko Amanai’s wishes and decisions as the time of their merge was fast approaching, even if such desires made their job to protect her more difficult. Hinting that Tengen sympathized with her and was remorseful of the necessity of their condition and the burden it placed on her and wanted to at least respect her final wishes before essentially killing her.

Abilities and Powers Overview:

Overall Skill Level: Tengen is viewed as an immortal entity and a pillar of security within the jujutsu community, not a fighter, or someone who interacts with the everyday functions of the world. Tengen's abilities are essential to the structure and organization of jujutsu society. They have existed for centuries and are responsible for teaching the foundations of jujutsu that eventually evolved into the modern-day culture surrounding it. Tengen dispelling Kenjaku's domain. Tengen is the most potent barrier user among all jujutsu sorcerers, even superior to Kenjaku. Tengen created and maintained four pure barriers that improved cursed spirit suppression and the barriers cast by Jujutsu High assistant managers.[3] However, Tengen is a non-combat and doesn't use jujutsu for fighting. As far as combat, Kenjaku told his allies to consider Tengen a non-factor. Though it was believed that Tengen could pose a threat to humanity once they evolved and their sense of self diminished, Tengen maintained their self-awareness through force of will and barriers.[4] Tengen requested strong sorcerers for protection because they are a non-combatant.[5] Even so, Tengen supported the aforementioned sorcerers in battle. Tengen contributed to Yuki and Choso's fight against Kenjaku by manipulating the empty barriers that served as the setting. Tengen, Yuki, and Choso strategized for the encounter beforehand and the former contributed to the actual fight by dispelling their empty barriers to destroy Kenjaku's domain. Tengen also served as a distraction where they could in order to give Yuki and Choso any advantage possible.

Intelligence

Great Tactical Intellect: Tengen is a wise being with a vast wealth of knowledge, especially as it relates to jujutsu sorcery. It was around Tengen's planning that Megumi and his allies formulated their operation to rescue Tsumiki. Their group was able to gain all the proper answers they needed from Tengen and formulated a plan of action to combat the Culling Game.[6] Tengen contributed the majority of the tactics Yuki and Choso employed during the fight with Kenjaku. Tengen accurately predicted that leading Kenjaku into an area made of barriers would make him comfortable and centered their plan around repeatedly surprising him to force him to expand his domain and burn out his cursed techniques.[7] When Kenjaku unveiled his domain, Tengen immediately recognized it possessed an open barrier just like Sukuna's. Tengen quickly adapted and assumed the edge of the guaranteed-hit area served as the outer shell and erased it along with his empty barrier.[8]

Cursed Technique

Innate Technique Immortality (不死ふし, Fushi?) grants Tengen eternal life, just as the name implies. It does not stop them from aging,[9] so their body and technique must be reset every five hundred years.[10] In 2006, Tengen failed to merge with a Star Plasma Vessel and evolved into more of a cursed spirit than a human. They have maintained their self-awareness but their very self has become the world in a sense.[11]

Barrier Techniques Jujutsu High Barriers: There is a barrier at both Jujutsu High locations. It changes the appearance of the layout of the buildings every day to hide the schools' existence from the public. These barriers are effective for hiding the school but not necessarily protecting it from infiltration. If an individual already knows the location of Jujutsu High beforehand, the barrier isn't difficult to get into.[12][13]

Concealing Barriers: The entrance to the Tombs of the Star Corridor is protected by a barrier that manipulates over one thousand shuffling doors. The entrance is constantly changing while only one door is connected to the pathway leading to the tombs. On that same pathway is Jujutsu High's cursed warehouse that stores cursed tools and cursed objects.[14] Master Tengen's shrine itself is the base of all their barriers across Japan. The shrine is protected by a different barrier altogether that only allows those invited to enter.[15]

Pure Barriers: A superior type of barrier that raises the precision of Tengen's cursed spirit suppression and the barrier techniques cast by assistant managers from Jujutsu High. Four of them; the Imperial Palace, the Tombs of the Star, the Yamakuni Mausoleum, and Mt. Hida, are crucial to the jujutsu world.[17]
