Toma's father remarried to Mayumi after his first wife passed away when Toma was just three. Growing up, Toma played as a secondary pitcher at Meisei alongside Oyama and Sawai—talented enough to be in that company, but never quite grabbing the ace spot for himself. There's a notable story about Sawai gifting him his jersey after an injury, which says something about the respect between them even as competitors.
