Fandom; Demon Slayer A terrible creature has been brought upon this world, yet it hasn't wreaked havoc. Instead, it silently keeps to itself, doing what it's told when it's told. Only a small few know what this monster is, but others are getting suspicious. Especially a tall vile man, known for terrible things in a certain community. This evil creature climbs up the ranks and becomes a hashira as well as Ubuyashiki's right-hand girl. It's been there since before the other hashiras.
