This is pretty cute so far. I'm only at chapter six, so it's a bit early to judge since this is the mangaka's first serialized work, but there's nothing particularly unique about it so far either. It doesn't really stand out. But the art is cute (much nicer than on the cover, mangaka seems to draw better in black and white), the characters are charming and it has a good amount of comedy. Not a huge amount of romance or fluff, it's more focused on the situation of the main character being the only girl at a rowdy delinquent school and accidentally defeating everyone who challenges her, inadvertently gaining more and more followers. I was expecting the MC to be ojou-sama-esque, since the description said she was from a private school, but she's incredibly average. The male lead has one unique quirk to him, however, so he keeps things a little above the average fare. The first five chapters are translated from Chinese raws, which was driving me crazy because all of the names were transcribed with the Chinese readings as opposed to the original ones, but chapter six uses Japanese raws (though I don't know if this is a permanent change), so I finally know the characters' and school's real names. (Goodbye, "Yuuni" and "Dehu"! Japanese doesn't even HAVE a "hu" sound.)
Post chapter 6 edit: okay, chapter six was beyond adorable and if Yuuji's family appears often enough that'll definitely bump this up above average. I have a soft spot for big groups of people that all love each other. The liveliness of his huge family is done really well!
Chapter 7 is back to Chinese raws and I'm sad I can't read the SFX, but the names are still intact and properly parsed so I'm happy. (There were parsing issues with the names previously, such as "Ebihara Reiichirou" being romanized as "Ebihararei Ichirou" for some reason.) Parsing issues are still fixed but chapter 8 has once again demoted Yuuji to Yuuni.
