Hatsune Miku: Bad∞End∞Night

Miku, a novice actress with little professional experience, is unexpectedly cast in the leading role of a new theatrical production penned by a legendary playwright. However, what begins as a career-defining opportunity quickly spirals into an inexplicable nightmare. In the middle of her performance, Miku is bizarrely pulled from the stage and thrust directly into the very world described within the script. She awakens inside a sprawling mansion, surrounded by seven mysterious inhabitants who exist entirely within the confines of the play's narrative. Trapped in this surreal reality, Miku realizes that the setting perfectly mirrors the events written in the original manuscript. The boundaries between fiction and the real world have completely dissolved, leaving her stranded alongside the mansion's residents. To find a way out and escape back to reality, Miku must join forces with the seven inhabitants to solve a critical mystery: a single page has been stolen from the script. Without it, the story cannot reach its conclusion, and none of them can leave. Together, they must scour the mansion and uncover the truth behind the missing page before they remain trapped in this endless performance forever.
