Mineko: Multiversal Insanity

Mineko: Multiversal Insanity is an upcoming science-fiction action psychological horror crossover film produced by Universal Pictures, Gingo, Glass Ball Productions, Onion Animation, ExQuality, Production I.G., Polygon Pictures, Studio Trigger, Toei Animation and distributed by Peacock. It takes place within the same universe established by the dark reboot TV series, Mineko, Supermoon, Chrysocolla: Vengeance, Onion: Fusion, Limit, and the 2020 anime reboot, Digimon Adventure: and serves as the series finales of both shows. In the film, Rumiko has been controlled by an unknown force, thus causing her to open multidimensional portals that lead to other universes while an agent from the multiverse is tasked to kill her before the universes converge, all while her friend, Kit Mineko, and other allies to try to stop him before he completes his mission while dealing with other multiversal enemies.

Plot
After the defeat of the overlord's son as depicted in The Fall of Kit Mineko, Kit Mineko and her friend now sister Rumiko, formerly designated RF-930, were about to enjoy their lives until Rumiko suffers from convulsions and voices by an unknown force making her descend into madness and causing her to open portals to the multiverse. Meanwhile, an agent from the multiverse has been tasked with killing her before the universes converge into one. While he deals with the situation, three girls, Zina Supermoon, Chrysocolla Reed, and Limit and the two human boys, Onion Mastori, Taichi "Tai" Kamiya and his Digimon, each from their respective universes, must deal with their respective enemies, the Aurks and the Shadow Army, who, with their human allies, have now allied to kill the citizens of the converging dimensions while Kit has to care for Rumiko during her insanity. Now, Kit, Chrysocolla, Zina, Onion, Limit, and Tai must group to form a team that can save Rumiko before her powers could be unlimited and used for evil and prevent the agent, the Shadow Army, and the Aurks from completing their objectives.
