On her way to locate him, she encounters Deimos—who declares that she will become his bride and return to the underworld with him.

Fleeing in disgust, Minako discovers the house her friend was pursuing and meets the endearing siblings Touko and Kaname Ooba.

However, the situation is not as it seems, and Minako quickly becomes entangled in a nefarious affair—all while being followed by the charming Deimos.
