Ace of Diamond: Monster Slayer

I saw a baseball magazine on the table:

Qingdao? Eastern Qing Kingdom? I've traveled to an anime!

The information about his own body also entered his mind:

Ryuzaki Gunji, 15, outfielder and fourth batter for the Marugame Little League team...

In that case, I'll make up for the regret the third-year seniors had when they lost to Inami this summer. I'm going to become a regular member of Seidou and make it to Koshien!!
