''Taboo-Tattoo'' is a FightingSeries by Shinjirou about a boy who is given an odd tattoo on his palm by an old man whom he [[SamaritanSyndrome saves from a thug]]. Not long after he's got it, he meets a mysterious girl, who punches him in the face, and later steals his phone. Running after her gets him [[CurbStompBattle more than he bargained for]], though, and he ends up drawn into the beginning of what might be the start of international war...
Became an anime starting in the summer of 2016.
* AlternateHistory: After World War II, a new kingdom emerged and quickly became a super power. It's called the Kingdom of Selinistan.
* AsLongAsItSoundsForeign: Izzy. That's just a nickname. Her actual name is Bluesy Fruesy. Yeah.
* BadAssNormal: Even before getting or activating his Spell Crest, Seigi was beating up thugs on the street and exchanging blows with Shields, though not very well in the latter.
* BloodyMurder: Invoked. [[spoiler: Tom and Izzy tell Seigi that blood is his activation key, though this is a lie.]]
* DespairEventHorizon: [[spoiler: Both Seigi and Izzy cross this when BB is consumed by Seigi's source, and when Touko is devoured. Izzy also [[AnArmAndALeg loses her left arm]].]]
* GreyAndGreyMorality: No side seems to be good, though admittedly that's through lack of information.
* MauveShirt: Strong contender for king of this trope. There are plenty of non-main characters who do get names and personality, but if they're the good guys, they could very well be offed in the very same chapter. Best examples are chapters 5 and 19.
* MentorOccupationalHazard: [[spoiler: BB.]]
* MoodWhiplash: ''Taboo-Tattoo'' has the frightening tendency to go from happy-go-lucky romantic comedy to bloody carnage in the space of a chapter.
* NewTransferStudent: Izzy.
* TheObiWan: BB.
* OlderThanTheyLook: Izzy.
* PowerOfTheVoid: Void Maker
* PsychoLesbian: By one indicator, Princess Ahyrabata.
* SphereOfDestruction: Void Maker
* SuperEmpowering: Spell Crests, apart from granting a unique special ability, also boost the person's physical abilities in a variety of ways:
* TheStinger: Episode 3's post-credits scene involves Iltutmish and R.R. Lakha being sent on a mission to assassinate Lisa, Izzy's friend.
** In Episode 5, Seigi is confronted by BB, who he tries to fight, but to no avail.
** Episode 6, a mysterious man discovers Brahman, and vows to defeat the Kingdom.
* TooDumbToLive: [[spoiler: Touko, who should have stuck with Tom's side than go to Seigi in Episode 8.]]
* TrainingFromHell: Seigi's grandfather.
* TransformationTrinket: Spell Crests need specific materials to activate. The material needed seems to be unique to each Spell Crest.
* WhamEpisode: Episode 8.
