Tanaka Shouta

A male student who was isolated in class because of his ugly appearance and dark, negative personality.
He was shunned by everyone around him, especially by the girls, who called him a "creepy guy" and hated him.
However, he becomes the "cure" that saves the girls on the island, and with Ichijo's encouragement, he gradually begins to take pleasure in bringing them to their knees, even though he feels he has no choice at first.
