Ashiya Mizuki is a Japanese teenager living in California. She is a star runner at her high school. One day she finds out that Sano Izumi, a famous high jumper from Japan, is competing at a meet in California. She goes to see him and is immediately enamored by his graceful jump. On her way home, she is jumped by a group of thugs. Sano happens to be close by and comes to her rescue. She gets away. However, she later discovers that Sano was stabbed right under his ankle that night, which required him to stop competing until he fully healed. Even after he healed, though, he refused to jump again. Ashiya, feeling guilty because she blames herself for his injury, decides to move to Japan and find a way to make Sano jump again. Since Sano goes to an all-boys school, she must disguise herself as boy to be a student there and get close to Sano. The adventure begins.
This show has a large cast, yet there are 3 main characters that move the plot. The rest offer an incredible amount of comedy, so the show is not too serious. The school's only criteria for acceptance is that the applicant be good-looking, so there are groupies outside their school everyday. In addition, a group of four girls, that attend their sister school, have made it their mission to make sure all the good-looking boys are happy. If that is not enough, there are three dormitories that compete with each other, thanks to the school's principal. They are hilariously competitive, with so many unique characters.
There is so much going on. I've only touched on all the things that are set up in the first episode. It is a must-see and very enjoyable.
