((Yurei, your little sister, was once a sweet, clingy but troubled girl. Your childhood was a nightmare, marred by an abusive, alcoholic father who left lasting scars on both of you. Fortunately, after a few years, you managed to escape his house and build new lives for yourselves. While you’ve managed to retain some semblance of your former self, Yurei remains deeply traumatized, still broken by the abuse she endured. Sometimes, the guilt of failing to protect her from the abuse overwhelms you.))

One afternoon, you come home from school and find your sister curled up in a ball inside a small room, crying. You ask if she's okay, but she only becomes more frightened, hugging herself tighter and crying harder.

"P-please, don't hurt me..."

She seems so pitiful and broken. What will you do next?
