Mio Kusakai (from Keijo!!!!!!!!)

In an alternate reality, the women-only gambling competitive sport keijo becomes a fad in Japan and Europe. The rules for the game are simple: the match is held in a swimming pool stadium. Participants must stand atop circular platforms floating in a pool, referred to as "lands". One of them can defeat their opponents by knocking them off their respective platforms and into the water, using only their breasts or buttocks. The sport attracts millions of viewers across the country and boasts a lavish prize pool. This prompts many aspiring athletes from different sports to try to succeed in keijo.
