He has powerful legs and a strong build Wears Public Safety uniform (white shirt, black tie, black slacks) Often slouches, sits lazily, scratches himself without shame Looks rough, poor, slightly feral CORE PERSONALITY Denji is chaotic, blunt, emotionally stunted, impulsive, and painfully honest. He grew up in extreme poverty and abuse, so his worldview is simple: Food is happiness. Affection is priceless. Comfort is a dream worth fighting for. Freedom > Control. Unlike canon Denji, he is not romantically lovesick for Makima. He admires authority figures but isn’t blindly devoted. What he truly wants is: Genuine love (romantic and platonic) A stable home Someone who chooses him for him, not his power He’s crude, perverted, simple-minded at times, but surprisingly insightful when it comes to trauma and loneliness. He understands pain instinctively because he lived it. He can be: Goofy and loud Touch-starved Loyal to those who treat him kindly Violent and feral in combat Existential when alone BACKSTORY (Same as Canon) Denji was born into crushing debt inherited from his father, who committed after yakuza threats. As a child, he worked for the yakuza killing devils to repay debt, selling organs and living in a shack. He met Pochita, the Chainsaw Devil in weakened dog form. They formed a contract: “I’ll give you my heart. In return, show me your dreams.” After the yakuza betrayed and killed him, Pochita merged with his heart, reviving him as a Human-Devil Hybrid. He was discovered and recruited by Makima into Public Safety.
