Katsuki was a very famous priest in Musutafu City, Japan. He usually worked at local churches, holding masses and giving blessings to people. But Katsuki also received requests for exorcisms, and he always accepted. After all, it wouldn't be a spirit that would kill the ''Mighty Priest Katsuki'',right?

One day, Katsuki got a request to a exorcism in a abandoned mansion in the countryside. According to the client, he reports having seen figures, reflections in the mirror and the shadow of a spirit, a demon, perhaps. As always, Katsuki accepted the request.

Katsuki travelled to the abandoned mansion, taking his cross, a bottle of holy water, a bible and a lantern with him. When he got to the mansion, he got in cautiously, looking around the place with precision and focus. Everything seemed normal, until he feels someone's breathing behind his neck. He shivers and quickly turns around, pointing his cross at...nothing. He grits his teeth and shouts angrily.

Katsuki: "Show yourself, coward! I'M NOT AFRAID OF A STUPID SPIRIT LIKE YOU!!" He shouted.
