Roka Shibasaki

The president of the Game Creation Club (Provisional). She refers her element as "Fire", but later states that her true element is actually "Darkness." Her main combat method is putting a bag over her opponents' head, rendering them blind, hence the darkness element. She carries a lot of spare bags so she can use them anytime. Despite having a small profile, she is referred as "Strongest Darkness" and is the strongest in school. She refers Kenji as her "important person", and shows jealousy when other girls approach him.
