Spell Down

Masato Kijima was once an excellent boxer, but now he just works at a boxing gym. He gets the chance to achieve a comeback as a trainer when boxer-to-be Ootani Yousuke shows up and begs Masato to train him. However, to become the champion, Ootani has to beat Otoba Yuuji who holds a grudge against Masato. Otoba wants revenge against Masato for the very thing that caused him to quit boxing. Will Ootani be able to beat him, or will Masato end up being the one to face Otoba in the ring?
