Zhandouban Geji!

In the near future, the emergence of enigmatic Nightmare Domes throws humanity into disarray. These structures pose an existential threat, seemingly impervious to conventional methods. Hope rests on a unique solution: the vocal power of "Swans," individuals with extraordinary singing abilities.

The United Nations responds by establishing IDUN, a specialized unit composed of six young idol singers from diverse backgrounds. Each member – Seika, Tamamo, Rose, Isabella, Katya, and Mo Xi – possesses distinct skills and must learn to harmonize their talents under pressure. Their missions involve confronting the unsettling phenomena emanating from the Domes, navigating complex interpersonal dynamics, and ultimately striving for collective strength. The series explores themes of unity, individual potential, and the power of art in the face of global uncertainty, presenting a blend of action and character-driven narrative.
