Ota Kunimaro

One of the elementary school students who comes in and out of the detective agency without permission.
A genuine occult geek, he has no doubt that ghosts, ufology, and unidentified creatures are real.
He usually reads yokai encyclopedias and ghost story books in his office, but when it comes to investigating occult cases, he actively cooperates and starts giving explanations without being asked to do so.
His long stories are boring to everyone.
He is into the monster "Sassy" which is said to appear off the coast of Saina.
