Mantis Imagin

Mantis Imagin (マンティスイマジン): The Mantis Imagin is a female masochist Imagin with the ability to spray a poisonous purple gas and wield twin rapiers as her weapons. Her goal is to allow a Miku Uehara from the near future to see her grandmother for the last time, as in her timeline she kept putting off celebrating her birthday with her grandmother up until her grandmother died before it could happen. Before the Mantis Imagin can complete her contract and go back in time, New Den-O defeats her.
