When humanity was oppressed by mysterious foes known as the Celestial Hosts, five exceptional mages joined forces to defeat them. In fear that these formidable enemies would return, the five most powerful mages, known as the Magia Vander, built a magical dome and a tower to contain them. Since then, the five strongest mages of every generation are tasked with monitoring the dome from the top of the Wizard's Tower. Inspired by this story, childhood friends Will Serfort and Elfaria Albis Serfort promised each other that they would climb to the top of the Wizard's Tower. However, now a sixth-year student at Regarden Magic Academy, Will's future looks bleak. Although Elfaria managed to join the ranks of the Magia Vander five years prior thanks to her unparalleled magical power, Will has no magical abilities whatsoever, attracting the ire of teachers and students alike. However, blessed with an exceptional physique, Will is able to slay monsters in the labyrinth and prevail against skilled magicians with the only aid of his sword and a few magical items. Determined to climb the Wizard's Tower at all cost, Will is determined to not let anyone or anything prevent him from keeping the promise he made to Elfaria.

Hailing from America, Jabberwock—a street basketball team with skills comparable to those of the NBA—has come to Japan to play an exhibition match against Strky, a team of former third-year students who once played in the Interhigh and Winter Cup. However, due to the vast difference in skill, Jabberwock easily wins. Their captain, Nash Gold Jr., mocks the basketball style of all players in Japan by comparing them to monkeys. Infuriated by the nasty comment, Kagetora Aida challenges them to a revenge match. Because of pride and the belief that the results will be no different, Nash accepts the challenge. Kagetora then assembles Vorpal Swords, a team composed of the Generation of Miracles, including Kuroko Tetsuya and Kagami Taiga, for they are the only ones who stand a chance against a foe that seems unbeatable from every angle.

High school student Rakurou Hizutome has a peculiar hobby of playing poorly made games—ones that are unbalanced or are filled with so many bugs that make them borderline unplayable. The few who share his hobby might recognize him by his in-game name, Sunraku. For his next game, Rakurou is recommended Shangri-La Frontier, a popular and well-received virtual reality game as a breather from the terrible games he has been playing recently. Once he boots up the game, Rakurou decides to sell off most of his starting gear to gain extra money, leaving himself with only a pair of boxers, a bird mask, and some weapons. He is instantly hooked as he meticulously levels up his avatar. However, after encountering some intimidating monsters, he realizes that he may have underestimated the challenge that a mainstream game can offer. As Rakurou progresses, he must draw on all the skills he has perfected from his previous gaming experience. Before long, Sunraku's eccentric playstyle takes Shangri-La Frontier by storm.
