Ishikawa Takuya, a high-school student who doesn't stand out in any particular way, is surprised when his principal asks him to take care of some transfer students. He is even more surprised to find that there are actually 30 charming female transfer students in his care, who have come from a boarding school that was destroyed in a fire! At first it seems like a dream come true, but then he notices their knives... and guns... What kind of school did these girls come from?

Wild's High has a 42-year history as a fighting specialized, girls only, private high school meant solely for the elite. It is also the place that Wild's-League is held: the most popular event in the country and the only place in the world where teenage girls have brutal fights with their lives on the line.

One year the school changed from a girls only school to a mixed gender school. The only male student, Song Jae Gu, has been granted a full 3-year scholarship regardless of grades. Being someone who had to spend every moment either working or taking care of his younger brother and sister, he accepted.

But after meeting Queen, the bloody champion of Wild's-League, drenching her in coffee, calling her a monster, and getting caught seeing her while she was taking a shower... his scholarship could prove fatal.
