The story follows , a high school girl with an incredibly specific and dangerous quirk: she experiences an overwhelming "fighting spirit" that compels her to be violent. To counter this and live a peaceful life, she carries a baseball bat—nicknamed the "Happy Syntholizer"—which she uses to knock out her own fighting spirit (manifested as a sort of split personality or impulse).
Some fan-translations or unofficial scans apply a "moral gloss" or censor contextual dialogue to make the extreme content more palatable. The raw manga presents the violence raw—unfiltered, unapologetic, and as the author intended. The visceral splash pages of street brawls, psychological breakdowns, and anarchic action lose none of their texture when read in the original. bouryoku banzai raw manga better
