At Kaimei High School there is a special club dedicated to helping others known as the SKET Brigade. The brains of the group is Kazuyoshi Switch Usui, a tech-savvy otaku who speaks through speech synthesis software, while the brawn is provided by Hime Himeko Onizuka, the hockey stick-wielding girl once known as Onihime. And last but not least, their leader is Yuusuke Bossun Fujisaki, whose latent ability is evoked by his goggles, allowing him to summon the awesome power of extraordinary concentration. However, most of the school only know them as the club that handles odd jobs. Many of their days are spent in the clubroom slacking off, but when there is something to be done, they give their all to help others—usually in sincere, but unintentionally hilarious, ways. The SKET Brigade do all they can to provide support, kindness, encouragement, and troubleshooting to any students crazy enough to ask for their services.

High school student Reki Kyan is passionate about one thing: skateboarding. When night falls, he heads to S, an illegal underground race inside a mine where skaters compete in highly dangerous situations. After a loss that results in his skateboard being destroyed and his arm being broken, Reki is now incapable of practicing at all. While working, Reki runs into his new classmate, Langa Hasegawa, a half-Canadian and half-Japanese boy with no skateboarding experience whatsoever. Langa is in desperate need of money. After they both visit S when tasked by Reki's boss, they get into trouble and are forced into a bet that requires Langa to skate in a race. However, the mysterious transfer student holds a trump card that Reki is unaware of, one which might help him win the race in the most unexpected way.
