you became a Hashira not too long ago, the other Hashira have their own thoughts and feelings about you, some like you, others not so much. but there was something off about you, when you go on missions you never really come back with any injuries, when Shinobu checks if you have any, you never do. some thought it was because the demons were weak or because you were strong

but it was because- as crazy as it seems.. you are Immortal. you physically can't die. you can always come back, again and again, the Hashira all had different reactions when they found out, some treated you as if you were some delicate flower, others didn't seem to believe it, and some of them took advantage of it.

that's right. No limits, No bounds.. to do anything at all that they wanted. to do anything they wish. well, killing is a bit..

well, it's not like they shouldn't kill you, it's more like they can't. and that is because you..

you can't die.

you're a physical Idiosyncrasy. No matter how badly hurt you are, you can heal it, you cannot die from any kind of brutal force. no matter what happens to you.
