空手小公子 小日向海流 13 [Karate Shoukoushi Kohinata Minoru]

Kohinata Minoru is a college student at a college that is popular for its sports rather than academic orientation. Although he starts out as a gymnast alongside his friend, Nana, Minoru is bullied by the higher ranked gymnasts. One evening, a karate student at the college, Mutou Ryuuji, witnesses Minoru being bullied and comes to the rescue... but his intentions aren't to save Minoru, but to drag him into the world of karate.
