Chifuyu is a young man of average height with light blue eyes, light skin, and his left ear is pierced. As a child, he wears his hair in a choppy undercut style, with the top dyed blonde and the sides kept his natural black. He is often seen dressed in the Touman uniform, but outside gang activities wears a large, white sweater, plain dark pants, and tennis shoes.
In the present, Chifuyu still wears an undercut hairstyle, but it is black and noticeably neater than in his youth. When meeting with Takemichi, he wears a pinstriped suit.

- Chifuyu's surname Matsuno means "pine tree, fir tree" (松) (matsu) and "field, wilderness" (野) (no).
