The opening episode hits you with full-power sword swings and spirit combat before you've even learned anyone's name, then never apologizes for the chaos. The show knows exactly what it is, unhinged ecchi comedy wrapped around genuinely entertaining fights, and commits so hard that the absurdity becomes the point. Characters feel like actual people riffing off each other instead of harem checklist boxes, the soundtrack slaps, and if you're the type who laughs at fanservice instead of feeling embarrassed by it, this becomes something you keep coming back to.

In Kawakami City, samurai heritage and ancestral power aren't just history lessons, they're currency. Students with strong fighting spirit climb the social ladder, and that emphasis spills over into what the school teaches. Second-year Yamato Naoe belongs to a close band of three girls and four boys who have stuck together since early childhood. When two more girls join the group, its long-settled balance starts to wobble, and daily life gets a lot livelier, especially since every girl in the band is a formidable fighter. What unfolds is a blend of action and character drama wrapped in romance, comedy and ecchi humor. The show commits to its absurd premise: samurai tradition is simply normal here.
