High School Debut

High School Debut (Japanese: 高校デビュー Hepburn: Kōkō Debyū?, also known as Koukou Debut) is a shōjo romantic comedy manga by Kazune Kawahara (河原 和音 Kawahara Kazune?). It was serialized in Japan by Shueisha in Bessatsu Margaret from 2003 to 2008 and collected in 13 bound volumes. The series was adapted as a drama CD and as a series of six light novels written by Yuu Kuramoto. The manga is licensed in North America by Viz Media, which published English editions of all 13 volumes between January 2008 and February 2010.

The series follows the relationship between Haruna Nagashima, an enthusiastic former softball star, and Yoh Komiyama, the cool boy she convinces to coach her in romance. It has been praised by reviewers as a standard shōjo manga premise made highly entertaining by Kawahara's handling of the characters, particularly the romantic leads, and artwork.

Plot
Haruna Nagashima gave her all to softball in middle school, and now that she's made her high school debut she's decided to give her all for a new goal. Getting a boyfriend and falling in love!

But a chance encounter with Yoh Komiyama provides her with the opportunity she needs. If he coaches her in how to become attractive, surely she can find herself a boyfriend!
