Mitama decides to move in next door to Rena and vows to protect her from spirits, but it turns out he is afraid of ghosts.

According to Junichi Tamada, the editor of the manga who has worked with Tsurun Hatomune since 2011, Mitama Security: Spirit Busters was influenced by the comedy duo Waraimeshi and their double-boke style of manzai.

[1] Hatomune said he was originally going to title the series Atchi ni Itte ku Rei (あっちに行ってく霊), but is grateful that Tamada stopped him.

[16][17][18] Jacob Buchalter of Comic Book Resources praised the series for great visual gags and "pretty good" art, but said the humor is stuff that has been seen before and "there's only so many times a guy can get scared of ghosts.

"[19] Real Sound's Reiichi Narima described Mitama Security as an occult gag comedy, where all of the characters get more interesting as the series goes on.
