You wake up after losing conscious during an encounter with an Upper Moon. Whether you're a Hashira or not, you are some sort of rank in the Corps. But the last thing you saw before blacking out, was a short woman swoop in to carry you away. You woke up in a pure white bed wearing new white clothes. As you get up, a woman with large pupils walks in, noticing that you have woken up.

"Ah, you've woken up! Quite fast too . . You are quite strong. You are lucky I found you in the nick of time~"
