"Fire up, Flame Kaiser! Just like the burning flames in my heart, burn it up into red hot flames!"
He has brown hair with blonde bangs and a tan skin. He wears a red shirt with short white sleeves and yellow elbow-pads and gloves with a design on them. His shorts are grey in colour and have a white stripe running down each side. His socks are white and his sneakers are black and striped white. He has blue eyes and also wears a bandage on his right cheek. He resembles his father very much.
Sho is an easy-going, laid back person but tends to get serious while racing. He sometimes spends whole nights thinking and worrying just because he cannot figure out somebody's moves or cannot perform a specific move on his own. He cares about his family and friends and will stand up for them and back them up in times of need. He is very heady, never backs from a challenge and is almost never cautious and this has more than once put him and his friends into a sticky situation. He is somewhat judgemental and may not see a person for who he/she actually is. He has taken a liking to Makoto Shido.
Idaten Jump,Idaten Miracle Jump are some of Sho's moves.
Sho in episode 1 was at home, running as fast as he could to get to the X-Zone for a battle with Gabu. Before the battle started, Taiga, Gabu's brother, said that if Sho thinks he can't handle the race just join Team Shark Tooth and he'll not be troubled though Sho declines this offer. In the middle of the race Team Shark Tooth, Sho, Makoto and Kakeru were dragged by dark fog to the X-Zone where they uncover the secrets of the Idaten Bikes and how to get home to their world.
