"Wandaba Style" is a 12-episode anime series that blends science fiction, comedy, and music into a unique narrative. The story centers around Tsukasa Kiriki, a high school student and the leader of the idol group Milky Way. Tsukasa and her groupmates—Yayoi Hanaki, Kanna Kirishima, and Shion Amase—are passionate about their music but struggle to gain recognition in a competitive industry. Their fortunes change when they encounter a mysterious scientist named Dr. Hikaru Hoshina, who proposes an unconventional plan to boost their popularity: performing a concert on the Moon.

Dr. Hoshina, a self-proclaimed genius inventor, has developed a rocket capable of reaching the Moon, but he lacks a crew to test it. He sees potential in Milky Way and offers them the opportunity to perform a historic lunar concert, which would undoubtedly catapult them to fame. Despite the absurdity of the idea, the group agrees, driven by their determination to succeed. The series follows their journey as they undergo rigorous training to prepare for the mission, facing both physical and emotional challenges along the way.

The narrative explores the dynamics within Milky Way as they navigate their personal struggles and aspirations. Tsukasa, the determined leader, often clashes with the more laid-back Yayoi, while Kanna and Shion provide comic relief and emotional support. Dr. Hoshina, though eccentric, becomes a mentor figure, guiding them through the complexities of space travel and encouraging them to push their limits. The series also introduces rival idol groups and external obstacles, adding tension and stakes to their mission.

As the story progresses, the focus shifts between the group's preparations for the lunar concert and their interactions with each other, highlighting themes of teamwork, perseverance, and the pursuit of dreams. The blend of humor, heartfelt moments, and the absurd premise of performing on the Moon creates a distinctive tone that sets "Wandaba Style" apart from traditional idol anime. The series concludes with Milky Way's climactic lunar performance, marking a turning point in their careers and solidifying their bond as a group.
