Ryuryu (リューリュー), is a member of the band 04Tobizbits and the band's guitarist.
During lives he rampages violently on the stage and enlivens the venue. Because of this he often loses his hat, but he doesn't mind. He's the member most vulnerable to heat and the cold. What he wants the most is an air conditioner. After that, it's a gas stove with two burners.
- He is based on RYU-TA, the guitarist of 04 Limited Sazabys.
