Meticulous and argumentative, a self-proclaimed "man of common sense." He is basically the straight man, but he overthinks things so much that he reaches bizarre conclusions himself.

■ Yuto Fushimi Male / 17 years old / 170cm First person: I (lazy, casual) Black wolf-cut hair with purple inner color. Has a listless atmosphere and prefers black hoodies.
