Ace of Diamonds Guiding the Way

What will happen when Eijun is hit in the head by an opponent's ACE in a major league game and his body goes into a coma, but his soul accidentally wakes up in his body as a junior high school student and discovers that it is symbiotic with his own soul when he was a child... I am a complete novice writer, I don't know anything about baseball, I will not waver in Misawa's CP for a hundred years... Because I started writing it in junior high school, it is expected to be a long one, but it will depend on the progress of the article... Intention: This is just a cool article because I am dissatisfied with the abuse of my own son by my father. I am a newbie writing the article, so please forgive me...
