Tough

This is a continuation of Koko Tekken-den Tough which ran for 42 volumes and followed the main character, Kiichi, when he was younger and was training under his father Seiko Miyazawa. This is a mixed martial arts fighter manga about the Miyazawa school of martial arts. Initially, it is about Kiichi trying to heal his father after he was nearly killed by his brother Kiryu but it then goes on to be less about that as his father recovers and some tournament style fighting begins.

A series dedicated to the father of Kiichi from the series Tough. This is a side story of the Tough series based around Miyazawa Seiko (Kiichi's father) and his brother Kiryu. Much of the same elements of Tough can be found here such as Mixed Martial Arts Fighting and alot of Violence.
