Whether you’re new to the world of Yumeutsutsu or a seasoned fan looking to complete your collection, this short story spin-off offers a compelling blend of Visual Novel narrative and Music Action gameplay.

Nestled in the outskirts of Imperial City Tokyo, within a quaint town that still cherishes old traditions, sits the unassuming office of indie studio Eureka Soft. In their meeting room, the atmosphere is thick with tension, as discussions unfold that could determine not just the future of Eureka Soft, but the fate of the entire world. Tempers run hot and frustrations mount, punctuated by cryptic utterances: words like "alien," "chunibyo," "Kansai dialect," and "obsessed" hang in the air.

Enter Ai Ohtori, who takes the stage—and to the beach—with aspirations of becoming a top-tier idol. Her dreams are intrinsically tied to the destiny of Eureka Soft, and indeed, the world itself.
