Prince of Tennis: Rikkai Dai's Twins

Yukimura Seiichi has a twin younger brother, Yukimura Yuto. He's always sick and frail, yet born with incredible strength and naturally gifted at everything he does. Their twin telepathy means Yukimura Seiichi can occasionally hear Yuto's thoughts, though only one way.

There will be crossovers with Detective Conan and Jujutsu Kaisen. In this Jujutsu Kaisen AU, there are two teachers, and the story is slice of life.

Rikkai Dai 16+3, no blind spots! No couples, just friendship.
