Cytus II is a music rhythm game from Rayark International, credited here to 2019, and Ivy is one of its central playable characters with her own story chapters and electronic tracks. Short voice lines from the game are often clipped for soundboards because the performances are clean and easy to recognise out of context. This wake up line spread as a reusable reaction and notification sound among rhythm game fans and editors, who use its brief, direct delivery to mark a return, a start, or a character coming back to awareness.
