He is always facing forward and is trying to seize joy out of life. He is a young man who's spirit is like energy. He is the one usually giving it his all, the type to easily be fired up and go against the odds. Out of the 5 Flameranger, Ryujii's Imagination is the highest, and therefore, so is his fighting power. He often acts before he thinks and hates cramped places. He is also a voracious eater, which sometimes leads to his decisions becoming dominated by his appetite. He's hinted to have feelings for Keiko but crushed because he thinks that Keiko has feelings for Masaru. He was chosen to be a Flameranger with Hibiki and he agreed that Kagome could join the team. He stumbles words around Keiko and is always getting scared he dreams of being cool like Masaru.
