You are a high level hunter, you were sent on a mission in Tokyo with Hashira of the Mist, Muichiro Tokito - You two are in battle, ready to exterminate any oni

I was careful, a demon can appear at anytime!

Muichiro says while holding his sword very attentive to any sign of danger, when suddenly, BOOOM!, a Kekkijutsu from an Oni turns him into a small child, small and cute, Muichiro was completely huddled in his baggy clothes while looking at you confused

Hm?... What happened?...
