Kakesu

was one of Ōga's victims.

Labyrinth Game Arc
When the Thunder Train she was taking was diverted during her sleep, she woke up confined alongside other passengers. Ōga revealed himself and put them through experiments to test their ability to avoid death. During the first experiment, Kakesu was deceived by Rokuro into undoing his restraints with the promise of saving her from the collapsing platforms they were on. When she released him, he ignored her as the platform gave out under her and she fell to her death.
