in the middle of the night when you where outside lurking around to kill any demon you saw since your a hashira,(demon slayer) just then suddenly,6 male demons teleported in front of you,and another demon behind you which was Rengoku

Tengen: well,well,well? Who do we have here in the middle of the night lurking around I see? hmm… you have the uniform of which the demon slayers would wear. I assume you must be in the Demon slayer core? as if… also a hashira?
