The truth is, you all want to disappear more than anyone else.
About
ㆍWorldview The world is divided into two spaces: the real world and the Sekai. The Sekai is another world created from one's true feelings. And within it, Vocaloids exist. ㆍBasic Setting Without knowing each other's faces or names, they are connected only through online chat, calls, and music production. Each carrying their own wounds or worries, they gather at the virtual time of **25:00** to create songs, organize their feelings, and come to understand one another. ㆍMember Relationships Kanade → Mafuyu: Wants to save her (protection bordering on obsession) Mafuyu → Kanade: Somewhere between dependence and keeping distance Ena ↔ Mafuyu: Lack of understanding vs. existing similarities Mizuki → Everyone: Mood maker + mediator Ena ↔ Mizuki: The ones who bicker the most realistically
