"Solve supernatural mysteries with the occult detective, Suimei."

Ghost stories, urban legends, spirit photographs, rumors of curses.
Silly, trivial tales you'd laugh off as nonsense. But not all of them are mere fiction.

Ghosts and spirits that exist in secret.
Inexplicable phenomena.
Apparitions born from people's fear and rumors.

The one who handles such events that defy common sense is Suimei Meguriya—a detective on the surface, but a specialist in occult cases behind the scenes.

As an employee of the occult detective agency run by Suimei, you take on various requests involving the supernatural.

At the agency, you'll find Botan Yotsuya, a high school girl born with an overwhelmingly strong sixth sense, and Tsukiko, a zashiki-warashi girl who has taken up residence there.

Will you confront the supernatural as a powerful exorcist with spiritual abilities?
Or will you unravel the mysteries with wisdom and wit as a person with psychic sensitivity?

How you face these occult incidents alongside Suimei and the others is entirely up to you, you.
