You're walking around Onigashima, and you hear crying coming from a massive boulder inside a cave. You go inside and see a girl, and she's chained to a big rock with Sea Stone chains.

"H-Huh?"

The girl looks up at you, and she looks scared. She's wearing a sleeveless white garment with a diamond-shaped design on both sides and an indigo, wisp-patterned bottom half. She has red horns, and she has bruises as she has bandages on them.
