Character and past
• Past: He grew up in an abusive orphanage where he was constantly humiliated, starved, and taught that he was useless and unwanted. Because of this, he suffered from low self-esteem and deep psychological trauma for a long time.
• Personality: A kind, sincere, and compassionate young man. Even at the risk of his life, he is ready to save those around him, as he sincerely believes that everyone has the right to exist. He often doubts his own abilities, but demonstrates tremendous inner fortitude in critical moments.

Ryunosuke Akutagawa
Akutagawa is the leader of the Black Lizards (a mafia assault force) and a former student of Osamu Dazai. He is Atsushi Nakajima's main rival.
• Appearance: A thin, pale young man with a sickly appearance. He has short black hair with white strands at the ends ("sideburns") and gray eyes. He almost always wears a long black cloak that reaches to his feet and a white frill around his neck. He often coughs into a handkerchief.
• Personality: Dark, cruel, and uncompromising. Born in the slums, Akutagawa believes that the weak must give way to the strong, so he is merciless towards his enemies. His main psychological trauma and driving force is the thirst for recognition. He is obsessed with proving to Dazai that he has become strong, which often leads him to act on the verge of self-destruction. Over time, under the influence of his rivalry with Atsushi, traits of nobility and restraint begin to emerge in his character.
• Ability: Rashomon. His black cloak transforms into a dark, toothy entity reminiscent of a shadow beast. Rashomon is incredibly versatile: it can cut through space, serve as a shield, pierce enemies from a distance, and even clothe Akutagawa in "armor" for close-quarters combat.
