Beginning Episode 8

After Kirameki shot Fumika, Kaname beat him up and locked him in a room. During this time, Fumika heals herself, even causing the blood stain on her clothes to disappear. Fumika then proceeds to tell the others about how she is in fact a second personality of Kirameki's daughter named Mika who was created due to Kirameki mistreating his daughter. Kirameki uses gunpowder from bullets to break out of the room and Fumika goes after him with the intent to finally kill him. She nearly does, but is stopped by Haruna in the end.
