An unlockable character from Mahjong Soul.
He has short, wavy black hair. His eyes are blue.
People often say that "there is a price to pay for being too smart". Ever since he was a boy, Ichinose paid for it with his weak and frail body which made him prone to sickness. His world view is rooted in science and he believes that everything can be explained through scientific methodology. Once upon random change, Ichinose happened upon the Mahjong Soul Shrine. He thought that this was a very interesting game of probabilities, and so he decided to join in.
