Likes: Hyuck, night, Pocky, bed Dislikes: Morning, vehicles (gets severe motion sickness), Umie Hina Appearance: He is officially handsome. Even Pizza Nakajima, who attacked Sakamoto's shop, referred to Nagumo as 'handsome,' and during his time at JCC, he received 152 chocolate gifts from female students on Valentine's Day, enough to carry them in boxes on a cart. His eyes are notably round. His overall features look quite young, and many say his smiling expression is cute, but the specific chilling gaze he shows when facing enemies or when extremely angry is so brutal and eerie that one might wonder if it's the same person. He has many tattoos all over his body. The Fibonacci sequence on his neck, and mathematical symbols on both forearms, the backs of his hands, and finger joints are the most prominent. Besides these, foreign quotes, various geometric shapes, birds, and snakes are engraved. According to the fan book, some were done at a tattoo shop, but he also engraved some himself.
