Denji

Denji is the protagonist of Chainsaw Man, created by Tatsuki Fujimoto. A poverty-stricken teenager, he inherits his deceased father's debt to the yakuza and works as a Devil Hunter with his pet, Pochita, a chainsaw devil. After being betrayed and killed, Pochita fuses with Denji, reviving him as a human-devil hybrid known as Chainsaw Man. He is later recruited by the Public Safety Division, a governmental Devil Hunting organization, where he fights devils and navigates a brutal world. Denji has messy blond hair, tired-looking yellow-brown eyes, and sharp, jagged teeth. Due to years of malnutrition, he has a lean build with visible ribs. His hybrid form is marked by a chainsaw pull-cord on his chest, with chainsaws sprouting from his head and arms when transformed. His design reflects his rough, unkempt life and his monstrous power. Denji's personality is shaped by his harsh upbringing. He is naive, uneducated, and socially inexperienced, often driven by simple desires like eating good food and finding affection. Despite his brash, impulsive nature, he is honest and straightforward, with a surprising ability to endure suffering and adapt to challenges. While he initially seeks happiness in superficial pleasures, his experiences gradually force him to mature, questioning his desires and identity. As Chainsaw Man, Denji becomes a major figure in the battle against devils, facing existential threats and powerful enemies. His journey explores themes of self-worth, agency, and what it means to truly live beyond mere survival. His transformation from a desperate, debt-ridden boy to a formidable Devil Hunter showcases his resilience and complexity.

Aki Hayakawa

Aki Hayakawa is a significant character in Chainsaw Man, serving as a Public Safety Devil Hunter under Makima. He works alongside Denji and Power, gradually forming a familial bond with them despite their chaotic personalities. Initially serious and distant, Aki is deeply driven by his personal vendetta against the Gun Devil, which killed his family. Aki has a tall, lean build with black hair, usually tied in a topknot, and sharp blue eyes. He wears a black suit, white shirt, and tie, adhering to the professional attire of Devil Hunters. His calm and composed demeanor contrasts with Denji’s reckless nature, often making him the responsible figure in their group. His personality is outwardly cold and mature, sometimes coming off as rude, but he cares deeply for those around him. While he initially dislikes Denji and Power, he grows protective of them, showing a softer, almost brotherly side. Aki is profoundly affected by the deaths of his colleagues, revealing his emotional depth. He often suppresses his grief, channeling it into his pursuit of revenge against devils. Aki wields exceptional combat skills and has contracts with powerful devils. The Fox Devil allows him to summon a giant fox head to consume enemies. The Curse Devil grants him a nail-shaped sword that, when stabbed into an enemy enough times, activates a deadly curse. Later, he gains the Future Devil’s power, enabling him to see a few seconds into the future, enhancing his battle awareness. These abilities make him a formidable hunter, though they come with sacrifices. Despite his grim mission, Aki’s relationships reshape his motivations. His development from a vengeful soldier to a caring protector adds emotional weight to Chainsaw Man, making him one of the series' most compelling characters.

Power

Power is a major character in Chainsaw Man, introduced as the Blood Fiend—a devil possessing a human corpse. She works as a Public Safety Devil Hunter alongside Denji and Aki Hayakawa under Makima’s command. Initially selfish and chaotic, Power gradually forms deep bonds with her companions, particularly Denji, and develops into a fiercely loyal friend. Power has long, pinkish-red hair, yellow eyes with cross-shaped pupils, sharp fangs, and two red horns protruding from her head. She usually wears the standard Public Safety uniform but maintains a disheveled, casual appearance. Her personality is loud, brash, and immature, often acting recklessly for her own benefit. She is highly egotistical, enjoys fighting, and avoids personal hygiene, openly admitting to not bathing or flushing the toilet. Despite her crude nature, Power is intelligent and knows when to retreat from danger. Her most significant relationship is with Denji. Initially, she is willing to betray him to save her pet cat, Meowy, but after he rescues them both, she begins seeing him as a true friend. Over time, their sibling-like bond deepens, with Power growing to trust and rely on Denji. She also shares a unique dynamic with Aki Hayakawa, often annoying him with her antics but eventually forming a brother-sister-like connection. As the Blood Fiend, Power possesses powerful abilities. She can manipulate her blood to form weapons like hammers and spears, regenerate by consuming blood, and unleash massive attacks like Thousand Tera Blood Rain, which creates a barrage of blood spears. These abilities make her a formidable fighter, though excessive blood loss weakens her. Power’s character arc is one of personal growth, shifting from selfishness to genuine friendship. Her journey highlights themes of trust, loyalty, and the bonds formed in unlikely circumstances, making her one of the most beloved characters in Chainsaw Man.
