The story of Furuya Satoru and his twin sister, Satomi. Furuya has always been a little introverted, but his sister is his opposite. She is outgoing and sarcastic, and a devil of a baseball manager (at least, according to Furuya's Junior high team). How will these characters adapt to Seido? Who should be more afraid: Seido or the baseball club? (Ace of Diamond FanFiction, I do not own any of the characters except Satomi and any original characters).
