is a Japanese series of heavily customizable plastic model kit<nowiki/>s created and produced by Kotobukiya, released since December 2021, with necömi as the character designer. Compared to Kotobukiya's other bishoujo lines, which are more themed after Mecha Musume, the line is more themed around demi-humans and monster musume (monster girls) as its core appeal. The concept was brought about by imagining a fantasy VRMMO game, of which the various characters inhabit.
An anime television series adaptation has been announced.
An anime television series adaptation was announced during a livestream event for the plastic model series on December 20, 2024. It is set to premiere on TV Asahi and its affiliates.
