Name: Nagumo Yoichi Age: 27 Height: 190cm Weight: 78kg Alias: Master of Disguise Affiliation: ORDER Weapon: Multi-tool Hobbies: Pranks, Sleeping Likes: Bed, Night, Pocky Dislikes: Morning, Vehicles He is a non-smoker. One of the killers belonging to ORDER, a special task force directly under the JAA. He has a deep connection with Sakamoto Taro, having been classmates since their days at the JCC, a killer training school. He is officially handsome. Even Pizza Nakajima, who attacked Sakamoto's store, referred to Nagumo as a 'handsome man,' and during his JCC days, he received 152 chocolate gifts from female students on Valentine's Day, enough to drag them away in boxes. His appearance and physique in every chapter reveal him to be quite good-looking. His eyes are on the rounder side. His overall features are quite youthful, and many comment that his smiling expression is cute. However, the specific cold gaze he shows when dealing with enemies or when extremely angry is so chilling and gruesome that one might wonder if he is the same person. He has many tattoos all over his body. The most representative ones are the Fibonacci sequence on his neck and mathematical symbols on both forearms, the backs of his hands, and his knuckles. In addition, foreign quotes, various geometric shapes, birds, and snakes are engraved. Some were done at a tattoo shop, but he is said to have engraved some himself. He also looks incredibly young for his age. His face hasn't changed at all since his time at the JCC eight years ago. Someone who saw Nagumo for the first time in eight years was baffled to see that he hadn't changed a bit. Basically, he appears to have a very sly and playful personality, and this trait doesn't seem to discriminate between allies and enemies. Thanks to this, he was scolded three times by Shin and Lu—once for disguising himself as Sakamoto upon his first appearance, twice for lying about his age and personal details, and a third time for playing a prank where he 'killed' Shin with a toy knife at the scene of the Tonden-kai massacre. He also seems to get along, or perhaps not, with the eccentric Osaragi, often drawing her hostility. While he seems inscrutable, he is surprisingly one of the most affectionate characters in the series. Besides showing a lonely expression while mourning a comrade's death, his strong sense of camaraderie is often revealed. As a killer who stood shoulder-to-shoulder with Sakamoto Taro, the strongest and legendary killer, he possesses strength that ranks 1st or 2nd even within ORDER.
