Fierce Fight!! Ichiban

Ichiban Jotaro, the successor to the ancient martial arts Musou style karate, is a tompachi bastard who wants to become a strong man and fights all the time. He enrolled in "Fierce Fighting Academy", which was founded to train the world's strongest man. He quickly became friends (?) with Yasukawa, who tried to take advantage of people's weak habits to defeat them, and clashed with Teshima of the Bronze Kaikan, who is famous for actual karate. He won by KO. His first class at school was a physical fitness test. It was also a way to go around the course while fighting anything, and the first person to come back would be the captain of the class. He fights against the martial arts Togajo and Fuyuki Takeichi and Takeji brothers who use the Mogami Konishi style of kobujutsu, and manages to defeat them. However, when he was about to reach the finish line at the top, his leg was caught by Yasukawa...
