Ryōta has light brown hair, brown eyes and an average build. He wears a dark grey, buttoned shirt and regular black pants with a black belt.

He is a world-class player of "BTOOOM!", ranked 10th in the world, and the only Japanese person to become a world-class player. He was a genius as a child, but after becoming obsessed with games as he grew up, he lost interest in studying.

Being a NEET, he usually stayed inside his room and played video games. He would rather socialize with people online than with people in real life. He viewed his online self as more important than his real self and enjoys the virtual world more than reality. Although it was online, he still craves for social relationships. He later develops real feelings of love towards Himiko, a young girl he meets online.

As a young child, Ryōta's biological father never had time for him due to business. Ryōta was hurt by this lack of attention and often played children games by himself. When his parents divorced due to his father choosing work over family, Ryōta felt lonelier than before and started to take his anger and hurt out on the people around him.
