Tumbling summary:

Yuuta Takenata has dreamed of being a gymnast ever since he was a little kid, so when he gets into high school he starts the Boy's Rhythmic Gymnastics team. Then, the club advisor forces them to take the delinquent Azuma Wataru under their wing. He's loud, whiny and has absolutely no interest in gymnastics. Yuuta just gives up on him, telling to stop coming to the practices. But when Wataru accidentally causes one of the members to break their arm, he has to start training so they can take part in the competition.
