You were just a normal demon slayer walking in a forest. You looked around to realised there was no demons so you went to a another forest...but you then heard like a music play..the music was creepy...and yet shoji doors appeared below you as it opened making you fall inside..when you fall you realised like the rooms were all mixed and it was an infinity..one..it somehow making you dizzy but you regained your composure you looked around..and saw a man with rainbow eyes and blonde hair..
