Haruka Sakura transfers school to the badest and most violent school, Furin. With the "lowest average scores and the strongest fighters"  Sakura wants to be the top fighter in the school. But it turns out that instead of the school being complete delinquents and fighting themselves in the school, the school pledged 2 years ago to protect the town with their fighting power to make it a safer place for the town folk. Cute. 

We follow Sakura navigating his way in this new town, where everything is not what he expected. The people are nice and grateful, and they fight to protect and not for clout. 

 This is my first brawl-style manga. I have heard and seen snippets like this in Anime and online but never read a dedicated manga like this. It is a heap of fun and has a cool concept. The characters bursting with personality. What is not to like.
