Izumi Kyouka was prepared to die. She’d stood before the weretiger, willing to die to fight her and save everyone else, willing to save even her from the bomb she wore. He couldn’t save her and she’d sentenced herself to death.
He saved her. She had killed so many, blood on Demon Snow’s sword, and she deserved to be punished, to be executed, so she walked herself to justice before he saved her again.
He didn’t understand, but Dazai did when he finally told her she could redeem herself.
She’d chosen execution. Sacrifice was no more fearful.
Kyouka saved them.
