Line #4 YMMV/MitamaSecuritySpiritBusters


1	* AbandonShipping: Despite a relatively small age gap and a fair amount of ShipTease, the chapters presenting Joh as a ParentalSubstitute to Rena (like the Mom Competition or the Parent-Teacher Conference) killed the ship for a lot of people who find the WifeHusbandry subtext too {{Squick}}y.
2	* AudienceAlienatingPremise: On first glance, ''Mitama Security'' has a rather unoriginal plot ("exorcist fights spirits to protect girl") coupled with an average art style which doesn't really attract readers, especially in a magazine as competitive as ''Magazine/ShonenJump''. Even as a pure comedy, it appears too soft and grounded compared to previous ''WSJ'' gag manga success like ''Manga/BoboboboBobobo'' or ''Pyū to fuku! Jaguar'' which thrived on their unapologetic SurrealHumor.
3	* EpilepticTrees: Because none of the spirits have backstories or even [[OnlyKnownByTheirNickname real names]], there are numerous fan-theories about who they were when they were alive which often fall into the EveryoneIsRelated category to explain why they are friendly with the main characters. The most common theory would be that Zobiro is Rena Haze's [[GuardianEntity late]] [[PapaWolf father]].
4	* FountainOfMemes: The author itself Hatomune Tsurun (that most people nicknamed "Pigeon") due to the various photographs of him doing silly things wearing an AuthorAvatar mask that many found CreepyCute which - coupled with ''Mitama''[='=]s unexplainable survival in ''Jump'' - lead to several jokes about him being [[BewareTheSillyOnes more powerful that he seems]].
5	* FridgeBrilliance: The whole "embrace your dark past" chapter 28 suddenly makes a lot of sense after Mr. Stripe explained that the Reihyoken technique is stronger the more its user is a DorkKnight. He was mentally preparing Joh to accept his own natural dork side in order to deal with the upcoming Popoki threat.
6	* FriendlyFandoms:
7	** Late 2019 to 2020 showed a large influx of comedy series coming to ''WSJ'' starting with ''Manga/MissionYozakuraFamily'' and ''Mitama Security''. This started a somewhat [[FandomRivalry friendly rivalry]] between all of them under the assumption that only one of them would survive in the end in an event that was nicknamed the "Gagbowl", with numerous crossover edits and memes. As both ''Mitama'' and ''Yozakura'' survived way longer than people anticipated and new series kept coming, the Gagbowl became very crowded and eventually occupied more than a third of the magazine's lineup.[[note]]''Mitama Security: Spirit Busters'', ''Manga/MissionYozakuraFamily'', ''Manga/AgravityBoys'', ''Manga/MashleMagicAndMuscles'', ''Manga/{{Moriking}}'', ''Manga/BoneCollection'', ''Manga/MaguchanGodOfDestruction'', ''Manga/HardboiledCopAndDolphin'', and ''Manga/MeAndRoboco''[[/note]]
8	** There are some interactions between the ''Mitama'' fans and fellow ''Shonen Jump'' series ''Manga/JujutsuKaisen'' fans due to both series dealing with [[OurSpiritsAreDifferent spirits]] and exorcists with diametrically different approach. The main joke is that Rena Haze is secretly a Special Grade curse user and [[TheDogWasTheMastermind the real antagonist]] of ''Jujutsu Kaisen''.
9	* GrowingTheBeard: For a series that was initially described as "action comedy", the first few chapters' jokes were really hit or miss and repetitive while the battles themselves weren't that impressive, taking a step back for the aforementioned awkward jokes. As the series progressed, became LighterAndSofter, and more characters joined the main cast, both of these aspect started to improve: the chemistry between the characters became more charming and funny while the (now rare) battles not only better utilized the characters' strengths but also created genuinely shocking OOCIsSeriousBusiness moments. The most obvious switch to the format was making Mitama the StraightMan instead of just the eccentric bodyguard he presented himself to Rena as, a move many fans liked.
10	* InferredHolocaust: It's probably best not to think too much about the fact that all the cute spirits in this lighthearted series probably died a remorseful death to remain as spirits on Earth in the first place, especially [[CuteGhostGirl Yuko]], [[DeathOfAChild Ta]], and [[UndeadChild Pi]].
11	* MagicFranchiseWord: At least now, people will know what "'''REI'''" means in Japanese...[[note]]It means "spirit/ghost", by the way.[[/note]]
12	* SpiritualSuccessor: Has seen many, many comparisons to ''Weekly Jump's'' 2016-17 series ''Manga/SamonTheSummoner'', due to both series centering around spirits, exorcist male leads, and gag comedy. Some fans of ''Samon'' even came to ''Mitama'' with open arms.
13	* TheyWastedAPerfectlyGoodCharacter: BODY. Despite their memorable design, very few (Neck, Leg, and Elbow) have any semblance of story relevance (and even then not that much), the others relegated to a background role just to fill the baseball team. We didn't even got see the wing powers of half of them in action!
