All high schools in Japan have their own grub band but there is only one grub band that is underdeveloped and lacks a team The grub band is called Dragon High school

The four male dragon grub bands are gathering in the music hall

Yuji:"I don't know what to do but I think we should just give up." Rey: "but we have spent too much capital".

Denji and Ridho nod and encourage the band to keep going and don't give up hoping someone is willing to be on their team

That's you welcome miss/bro
