Watch on SFlix. Sawaki Shohei (Yabe Kyosuke) is a strong fighter with a strong manly spirit and a weak heart. He is asked by his classmates to help them in a fight, and in no time at all he knocks out the rival Morikawa and his friends, but a few days later, his friends are turned back by a boxer who calls himself Azuma (Motomiya Yasukaze).
