Brothers Conflict + Kuroko's Basketball: Kuroko

Kuroko achieved his dream, but injured his hand and could no longer continue his professional career. He didn't feel regret, because he had no regrets in his heart. Then an unexpected accident turned his life upside down. Kuroko became his counterpart from a parallel world. In that parallel world, Kuroko's left hand was already injured, so he couldn't play basketball anymore. Even more bewildering, this Kuroko was a girl. The story begins after the failure of the attempt to win over the goddess Ema, who then leaves the Asahina family. Kuroko is still called Kuroko. Expect all sorts of absurd, melodramatic Mary Sue tropes. The characters will definitely be out of character, there will be plenty of shameless antics, and the System will make an appearance.
