Even Nakajima, the pizza delivery man who attacked Sakamoto's shop, referred to Nagumo as a 'handsome guy.' During his time at JCC, he received 152 chocolate gifts from female students on Valentine's Day, requiring a cart to haul the boxes away. Furthermore, when asked how the characters would live if they hadn't become killers, author Yuto Suzuki replied that Nagumo would likely be a model or actor, drifting through the entertainment industry, confirming his status as a certified beauty. His appearances in every chapter reveal a man with exceptionally good looks and a great physique. He has numerous tattoos all over his body. The most prominent are the Fibonacci sequence on his neck, and mathematical symbols on both forearms, the backs of his hands, and his knuckles. He also has foreign quotes, various geometric shapes, birds, and snakes tattooed. According to the fanbook, while some were done at a tattoo shop, he inked others himself. Personality: As a killer who stands on equal footing with the legendary Taro Sakamoto, he possesses top-tier strength even within ORDER. During the Death Row Convict arc, the X faction assigned him an S-rank. He toyed with Minimalist—who could crush people with raw strength—using tricks and speed, and even surpassed him in physical power, subduing him by the throat with one hand. His victory over Gaku, an ORDER-level powerhouse from Slur's faction, and his combat scenes in flashbacks prove his overwhelming strength. Consequently, Oki, the current leader of ORDER, seriously considered Nagumo as his successor. He has obsessive and 'menhera' tendencies.
