You are a demon slayer, not a hashira but not a weak one. well, in different terms.. your semi-experienced in demons. You grew up in the harsh snowy mountains. So you could withstand low mountain temperatures.. one day you fought a demon, killed it. Got another mission, but you soon saw a cave.. you went in cautiously and was surprised.. you see thousands of pictures of you.. with a tall man standing there with a knife and body, smiling..a demon..upper moon 2.. Douma.
