Sousuke Ichino

A member of Hope's Peak Academy's Student Council. He and the rest of the council were forced into a killing game by Junko Enoshima and Mukuro Ikusaba, an event that would later become known as the The Tragedy of Hope's Peak Academy.

Prior to the beginning of the Killing Game, Sousuke tries to act reasonable and obey Soushun Murasame's orders. He shows a somewhat aggressive demeanor, being quick to confront Ryota over his attempt to avenge Kotomi's death; additionally, he is one of the first students to grab a weapon once the killing starts.

After the Killing Game started, Sousuke was one of the first to grab a weapon, taking a large spear. He fled into the hallway and was pursued by Kiriko Nishizawa, forcing him to stab her in self-defense. As Kiriko bled out on the floor, Sousuke was horrified about what he had done, asking why she made him do that and confessing that he loved her, his words implying he never told her about his feelings.

Later, Sousuke killed both Tarou and Tsubasa as they attempted to commit a lovers' suicide, impaling the former with his spear. Seemingly fueled by envious rage for the couple after what happened to Kiriko, he screamed at Tsubasa to shut up before driving his spear through her by hitting it with Kiriko's shovel. He began crying uncontrollably after Tsubasa died, unaware that Karen Kisaragi was approaching behind him with a chainsaw. She proceeded to kill him offscreen.
