Ryunosuke is the most expressive member of the team. Due to his side-hobby as a Kabuki dancer, Ryunosuke has a flare for the dramatic. This often manifests whenever he undergoes a personal failure; often inflicting self-punishments on himself. He is also the most dedicated of Takeru's vassals. Ryunosuke has a tendency to judge those around him and will lash out at practically any dissent. Despite his quirks however, Ryunosuke is a welcome addition to the Shinkengers.
The Shinkengers can utilize the generational power of Mojikara, which allows the wielder to form any object immediately available to the imagination by drawing it's Kanji into the air using the ShodoPhone or any painting device. Ryunosuke carries within him the Water Mojikara.
