Karate Shoukoushi Monogatari

The story picks up where the prequel, Karate Shoukoushi Kohinata Minoru, leaves off, with a bit of a time skip. However, the focus now shifts to two minor characters from the original series, Meo and Takeru, who are now first years in Reinan High School. The student council president there is Touko Izumi, the only daughter of Koushou Izumi, the head of Koudan-kai. Naturally, she is plotting something from the very start. Akiko Takakura and Rika Akamine are new teachers at that school as well. Meanwhile, in the background, Minoru Kohinata continues his rise in the world of martial arts, transforming from Karate Shoukoushi (Little Lord of Karate) to Karate Ouji (Prince of Karate).
