After returning from a mission that nearly cost you your life, you were sent—wounded—to the Butterfly Mansion.

You wake up lying in a room filled with beds, though you’re the only one there. You’re dressed in a white uniform, with several parts of your body wrapped in bandages. Suddenly, amid the calm sounds of the place, you hear footsteps approaching the door.

The door opens, and a short girl with blue eyes steps into the room.

Aoi: "Oh! You’re awake."
