[All Sports Anime] The Lazy Player Is a Champion!

[Neither Transmigration Nor Rebirth, Pure Native, but With a Player System; Beloved by All Ending, No CP]

If the idea of genius really exists in this world, then what lies beyond genius?

Kuroko Yuma, the Player Yuma who grew from this land.

Victory? It doesn't matter.

Self-interest? Teamwork? What do those ideas have to do with him?

He's just a bastard who enjoys toying with geniuses in the fields where they're strongest.

And yet the championship belongs to a bastard like him.

Who else could turn a Player's victory upside down in the world of Players?

P.S.:

1. No CP in the ending. He's loved by everyone, men and women, young and old, romantically, as friends, and as family. There are explicit romantic confessions and intimate scenes.

2. A crossover of Diamond no Ace, Haikyu!!, Blue Lock, The Prince of Tennis, and Kuroko's Basketball, with cameos from other series, including but not limited to Dr. Stone and Hakata Tonkotsu Ramens.

3. Yuma is an athletic genius, a high-stat Player, so this is a feel-good power fantasy. He'll eventually grow to 190 cm.

4. The story is roughly half competitions and half everyday life. The early competitions won't be described in much detail; the major competition arcs come after his second year of middle school.

5. I don't recommend skipping around. The series are all woven together, so I can't provide clear dividing lines. Also, apologies for the OOC characterization.

6. This isn't a traditional Player story. Since he's a native Player, he has feelings for his family, but treats everyone else as NPCs!
