Biff Sukēto

Biff Sukēto is a NOT student that attends DWMA with his sister, Rhythm Sukēto.

Appearance
Biff is the perfect stereotype of a Skater punk, especially his attire. He wears a Beanie with an alternate version of the academy logo, a white and red sleeveless tank, yellow boardshorts, and red sneakers. He even has an attitude to match it, as shown below.

Personality
Biff is very aggressive, which is holding him back from becoming an EAT student (Mainly because if a human bothers him on a mission, there is a chance he might take their soul, drawing him toward the path of a Kishin). Rhythm helps restrain his anger with her soothing personality, but it can only go so far. He also will beat up anyone who disses his sister. Despite this, he can be a kind person if he wants to be, as shown whenever Rhythm or one of his friends gets hurt.

Weapon
Biff is a Board-Meister partnered with the demon board Rhythm. He is a master of the Board Weapon.

Soul Resonance: Chain Grind
A version of Psycho Hunter where chains are sent flying in a winding manner, then Beat grinds it on Rhythm, increasing speed and impact, before finally hitting the target head on in their weak spot.
