Tamura, a junior at the same company Satoru Mikami worked at. The two also went to the same university. He is Miho Sawatari's fiancé.
He is bright, cheerful, and without a hint of sarcasm, quite the lovable guy.
He is also trustworthy, seen when he accomplished Satoru's dying wish to destroy his PC.
He also promises that if he ever had a kid he will be named Satoru.
