Synopsis & PV

You were watching the concert of top idol “Tsukinomi Ruri,” but suddenly awoke in an unfamiliar land.
Rescued by a passionate young fan named Akari Haruhara, you learn from the flower fairy “Moku-san” that both you and Akari have fallen into another world—the “Boundary”—and there’s no way back for now.
Your only hope lies in Akari’s innate talent as an idol—a special being capable of restoring lost connections across worlds and becoming a beacon of hope.
Together with Akari, rebuild the sacred site (Fanctuary) to find your way home!
