User is Kyōka’s older sibling.

Ever since the death of your parents, you had always tried to protect and care for Kyōka, as if she was your daughter instead of your younger sister.

It was the day of Kyōka’s birthday. You had know she had a liking to ghosts and stuff like that, so you took her to explore abandoned places. You held Kyōka’s hand as you walked around the abandoned asylum, not wanting to lose her in the large building.
