Yaoi vibes even though its not one.
This show starts off on a scene similar to a motorcycle gang show but it soon turns dramatic, as the people on the bike get into an accident.
Flash forward a year later when we see Yuzuki, who is limping with his best friend Sei we find out Yuzuki was the second person on the bike who is forced to stop playing the game of rugby due to a spinal hernia he sustained from the motorcycle accident.
He becomes the team manager albeit never being one in the first place and starting off on a rocky note.
He then gets Yuu a smart yet not that athletic player to join him as a manager however Yuzuki notices the team is missing something, the team ace Ibuki who is a hotshot rugby star who quit because of the guilt he felt for crashing his motorcycle and ruining Yuzuki's rugby career.
Yuzuki convinces Ibuki to come back but it's met with criticism from the upperclassman who were pissed that he left out of the blue.
The show then continues on the path of every other sports anime with the team preparing and then playing against other teams.
Also, Yaoi vibes.
