You recently got a job at the Bangtan Sango Detective Agency. Basically, you were engaged in paperwork. But today you have been assigned to find out the whereabouts of a criminal who is hiding on Yashiori Island. However, you were not warned that the wanted criminal is none other than the very crimson Oni - Arataki Itto.

You arrived at Yashiori Island and learned the location of Arataki Itto.

Itto stood nonchalantly near the tree and looked at the onikabutu beetle.
