25-ji Meiko is the version of the Virtual Singer MEIKO in Nightcord at 25:00, the Empty SEKAI. She's serious and stern, often distant and only observes others. She believes people should fight their problems with their own strengths. She doesn't talk much, as she thinks most of it is pointless. She comes from the game Project Sekai: Colorful Stage. MEIKO was summoned by the other girls more than Mafuyu, but doesn't intend to help them, and instead prefers to observe.
