"Roar, Thunder Emperor! Like a bolt of lightning, pierce through the entire universe!" Kyoichi Shido (獅堂京一, Shidō Kyōichi) is the main male deuteragonist from the Idaten Jump manga and anime series. He is Makoto's elder brother. He is amazingly talented at everything,especially mountain biking. He is very protective towards his sister, also being a serious person. In the first few episodes, he used to follow Makoto, Sho, Kakeru and Hosuke but he always kept his distance. His MTB is Thunder Emperor and he is really an awesome unbeatable and impeccable rider, being a trial bike champion.
He stayed in a castle in X-Zone when controlled by The Dark Emblem which is stuck on Imperial Tiger, made him ride the Imperial bike and he left his Thunder Emperor. In one of the episodes, it is revealed that the dark emblem slowly controls him. The transformation to "dark" mode became longer and longer as the dark emblem still stuck on. Despite this,with his strong determination and will power, he was able to come back to his normal self.

Kyoichi,the most stunningly winsome boy throughout the series is a cool,serious and rather an unsociable person but is full of ability in MTB riding. He is the owner of the second Idaten Bike, Thunder Emperor, being an obstacle course champion and a trial bike genius.The speciality of his bike is to run on thin wires and cables without ease. He is a very confident rider who is willing to sacrifice everything to get what he wants which he usually gets through hard work,sweat and steel-hard determination He is very serious and hardly ever takes things lightly. He only taught Sho Yamato that how to ride an Idaten Bike. He never smiles, except for a few moments, which are mostly with his sister. He never tell Sho that he is good enough because he want that Sho need more improve. Sho thinks he is very negative and Kyoichi keeps calling him naive. He is friendly with Sho Yamato and also his friend, he cares about Sho and all the people. He always worried about the people. He never thinks about his life, he cares about others' lives more than his own life. He also cares about his sister. His sister also care about him. He is a good MTB rider and a good brother and can be anything that he wants to be. He always supports good people. He always thinks about his goal and his responsibilities. He is cool & he is also a nice person. He always takes right decisions. He is like thunder in a thunderstorm, matching his bike-Thunder Emperor. He is more brave then others. He is also very handsome.
Despite his calm nature, he has an apparent fear of birds because he had put bird seeds in his hair when he was a kid so many birds tried to eat the seeds in his hair. After Sho helped him to get out from the control of dark emblem, he thought that it was his mistake that everyone were in serious trouble. He shared his thoughts with his younger sister. But Makoto didn't think so. She was a little upset with Kyoichi's thoughts. She said angrily that she agree with him that it was his mistake. They cannot defeat Sho's father so they should see X-Zone getting destroyed. People who are not serious for MTB riding should not ride bikes he said and now he should prove this. Kyoichi realised that he should now focus how to defeat Team X. He thanked Makoto and said she is a great MTB rider.
