Two hundred years have passed since the hero Bartz and his companions saved the inhabitants of Planet R—a world where crystals control the natural elements—from the threat of Exdeath. However, agents of the wizard Ra Devil steal the crystals of Earth, Fire, and Water. With three of the four crystals in his possession, Ra Devil seeks to claim the Wind Crystal, the final piece he needs to summon the destructive god Deathgyunos. Novice summoner Linaly—a direct descendant of Bartz—lives with her grandfather Hassam. After receiving an ominous message about the Wind Crystal, Hassam travels to the Wind Temple. Concerned for his safety, Linaly suggests that they make the journey together. On their trip, they encounter Prettz, a rowdy yet amiable swordsman, who is captivated by the young girl and accompanies the duo for his own mysterious reasons. During a battle, an antlion monster injures Hassam, leaving him bedridden. As a result, the responsibility of securing the Wind Crystal falls on Linaly, with Prettz assuming the role of her guardian as they continue their perilous adventure.

Following a successful graduation performance, Yuuta Hoshitani and the rest of the second years begin preparations for the upcoming Ayanagi Festival. This year's festival is the first time the students will be without their Kao Council mentors, giving them the creative freedom to do what they want. Hoping to perform alongside each other for once, the second years decide to put on a joint production together. The festival’s opening ceremony will also serve another purpose—to reveal next year's Kao Council candidates. The Kao Council announces that Team Hiiragi was selected for the opening ceremony performance, preventing them from participating in the collaboration. This shocks and enrages Hoshitani and the others, driving a rift between them and the Kao Council. In an effort to realize their dreams, the students begin to hatch a plan to ensure that all of the second years can perform together on stage.

The balance of the world is deeply shaken when malevolent gods known as the Four Perils break their seals and disappear together with eight million minor deities. In the absence of gods, lands become barren and famine looms in the country of the Eight Immortals. In order to restore the fragile harmony, kashi—gifted dancers and singers—must hunt the missing gods in other realms, use their performance skills to charm the deities, and seal them using the power of their rosaries. Although a master dancer, Ichiyou is ridiculed by his peers for his lack of singing talent. Nonetheless, the young kashi is tasked by the Eight Immortals to bring back the Four Perils before the world plunges into complete chaos. Helped by his familiars Tenkou and Kaka, Ichiyou embarks on the perilous mission given to him, with his search leading him to modern-day Japan. If he hopes to save the world, Ichiyou must also uncover the truth behind the Four Perils' disappearance—but this event seems to be disturbingly intertwined with his own past.
