I've always found the setting that Akaashi has never lost since he was a kid very scary. There must be someone better than him in a certain field, right? It would be an exaggeration to say it was omnipotent.

The heroine is a sports idiot, with a Buddhist-type and gentle personality. She is a bit unaccustomed to being happy because she has been playing Go since she was in elementary school. Her chess skills have grown much faster than children of the same age. She is considered arrogant, cold and unapproachable by the chess kids she knows. She also took the professional exam early due to family reasons and did not have much childhood campus life. Except for her enlightened parents who can communicate with her, she has no one to communicate with, so she often thinks in her heart or immerses herself in the world of chess in her imagination, which makes it difficult to do other things. She easily gives up and feels that she can do nothing but play chess. In fact, she is escaping from reality.

After his mother passed away, he temporarily left the professional chess world for psychological reasons. He tried hard to face the reality and was admitted to Teiko Middle School near his mother's hometown.
Concept: What would happen if Akashi was crushed by someone in a certain aspect?
