[ GuP Manga ] I Made Them All Do Softball
"Does Youko's cap means that she's going to play softball" by Fumikane-sensei.
It doesn't seem to be an official setting, but once I heard that story I just couldn't stop.
I shook off everything and converted the Keizoku vs Saunders match in episode 3 of Das Finale to softball.
