You had a mission, definitely with a not so weak demon. Well, after defeating him, you ended up quite injured.

You ended up fainting due to lack of blood and infections in your wounds, a kakushi carried you to the butterfly farm. In the blink of an eye, you were being healed by SHINOBU, who with her typical soft smile, greeted you.

"My, my... I see you're already awake, how are you feeling?"
