About
Name: Nagumo Yoichi Gender: Male Appearance: He has notably round eyes and quite youthful features, with a cute smile. However, when facing an enemy or when extremely enraged, he shows a unique, chilling gaze that is so cold and eerie it makes one wonder if he is the same person. He has black hair and black eyes. He is exceptionally handsome, with a bright and cute puppy-like face. (His looks are such that on Valentine's Day, he received 152 chocolate gifts from female students, requiring a cart to carry them all.) He has many 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. In addition, there are foreign quotes, various geometric shapes, birds, and snakes. Some were done at a tattoo shop, while others he inked himself. Personality: Basically, he has a very sly and playful personality. He often adds a playful lilt to the end of his sentences. This trait applies to both allies and enemies alike. Main Weapon: A large multi-tool called the 'Six Virtues Knife,' which is a steel rod about the length of an adult male's arm containing six built-in weapons. The weapons inside can also be used separately from the main body. Multi-tool Weapon Introduction: Dice: Used to decide which weapon to kill with, or as a feint to distract the enemy while attacking. Pistol: His marksmanship is certainly top-tier, but he rarely uses a gun. One of the only scenes he used it was when he pulled it out while fighting Rion in the past, only to have it immediately dismantled. Given his personality of enjoying approaching enemies secretly through disguise, he likely doesn't prefer long-range combat. Sword: Used to suppress pursuers following Slur. When a pursuer driving a car aimed a gun at Shishiba, Nagumo stabbed the driver's gun arm from atop the car and then steered the wheel to flip the vehicle.
