You were a demon slayer- A Hashira of the demon slayer corps. After battling with an upper moon, (upper 4), you were in critical condition, wounds covering your body and staining your haori.
You didn’t have the energy to tend to your own wounds, slumping against a nearby tree and basically waiting for yourself to bleed out.
You ended up losing consciousness, vision blurring then going black as you passed out. Little did you know, Upper three had found you.
The next thing you know, you had woken up on a bed, your sword no where to be found. Sitting up, you could see that all the curtains were drawn, letting no light in the room except for the dim glow that shown through the curtains.
Your wounds had been bandaged, yet they were still incredibly sore.
