Taking place at Winford Academy located in an old town called Helen's Hill, the story is all about knights and the sport of jousting. At this school, students learn how to become knights, ride horses and joust properly. The main character is a young man named Takahiro Mizuno who was training to become a knight and jouster but after suffering an injury he dropped out of the knight program and joined the begleiter (assistant) program instead. Due to his animal handling skills and former experience as a jouster, this makes him a hot commodity. Multiple beautiful girls in the school want him to become their personal begleiter, though Takahiro always refuses their offers. One day a bizarre accident causes his friend, Mio Kisaski, to be challenged to a jousting duel despite her not actually being a knight. Takahiro agrees to become her temporary begleiter, but that ends up only being the beginning of their partnership as she enrolls in the annual tournament.

The All-Star Tournament is a three-day event that allows e-sports participants from various professional clubs to display their skills, while also giving casual Glory players the chance to interact with pros in the flesh. Retired top-tier Glory player Ye Xiu agrees to watch the tournament together with Tang Rou and Chen Guo after the latter manages to get ahold of three tickets. It is a strange sensation for Ye Xiu, as unlike previous occasions, this time he attends the tournament as a spectator, not a participant. However, despite his attempts to keep a low profile, events in the All-Star Tournament may force the former Glory legend back into the limelight.

In professional sumo, there are no weight classes. It's a savage sport where the strongest survive, and anyone willing to test their mettle can step into the ring. There is, however, a minimum size requirement to be a pro sumo wrestler, and young Hinomaru Ushio, incredibly talented and hardworking though he may be, does not meet that requirement. This small boy has big dreams of reaching the highest class of sumo, Hinoshita Kaisan. The only way he could possibly go pro is if he becomes the High School Yokozuna, a title given to the strongest wrestler in high school tournaments. Ushio is under a lot of pressure, as well as a time limit. If he can't show off his skills in the high school tournaments, he may lose his chance to go pro permanently, and the odds are stacked against him. Instead of enrolling in Ishigami High, the best school for sumo in Japan, he enrolls in Odachi High and must build a sumo club from the ground up with the one devout member Shinya Ozeki. Odachi High is the true underdog of the sumo world, but Ushio has to push forward with all his strength if he is going to make it professionally.

Takashi Kamiyama is your typical mild-mannered high school student—polite, aloof, and pacifistic, with a slightly above-average IQ. But would your average high school student really enroll himself at the infamous Cromartie High School, known as a breeding ground for the toughest delinquents out there? Apparently so, as that is exactly what Takashi does, though for reasons he'd rather leave unmentioned. However, one thing is for sure: the hard-boiled rabbit in a den full of hungry lions is never going to have another dull day. And how could he, now that he's surrounded by mohawked punks, obnoxious robots, and... gorillas? And was that Freddie Mercury riding a horse down the corridor? Follow Takashi as he earnestly dedicates his new high school life to better his school's reputation while his classmates are hellbent on wreaking havoc.
