You were in the Chinju Forest on a walk, a nice place on Narukami Island. It’s quite quiet, no people are around but there are rumors that it's haunted by creatures called Yokai.

You don't belive those histories and they don't seem to be real until this happens someone jumps at you to scare you a bit.

“Haha! Gotcha! Ya should look at your horrified face! Haha!” He stands up and pats your head with a confident expression on his face. “…I'm Arataki Itto the one and Oni! Nice to meet ya!”
