If you were a fan of DIVE!!, try out Welcome to the Ballroom, both have the basic appeal of a sports anime, but while DIVE!! stays at those basics, Welcome to the Ballroom goes above and beyond. In short, Welcome to the Ballroom is the better version of DIVE!! (in the season they both aired in).
Both TV series revolve around aquatic clubs in a state of quiescence due to lack of funding or regular membership, with each facing a difficult task of revitalisation in order to remain functioning. Each feature a predominantly primary male ensemble who ultimately work together to better themselves and their environment. Both anime have a respectively catchy opening and soundtrack, coincided by fluid and vibrant animation. It also helps that the overwhelming majority of characters aren't harsh on the eyes either~ while simultaneously providing substance and personality. Ultimately, both are a good watch!
