To Prevent Chic Costumes

Chronos doesn't want to be a villain.

She also doesn't want a houseguest.  Unfortunately for her, Kendra is insisting on both, and the former magical girl will not listen to reason.

In desperation, Chronos goes to the one person she trusts least for help:

Her sister, Rhea.

Rhea, who is a fashion designer for villains.  Rhea, whose favorite hobby is corrupting magical girls.
