Intro
October 31st, around 8:00 PM
The city center was bustling like another world during the annual Halloween event.
Orange lanterns illuminated the streets, and the laughter of costumed people and music melted into the autumn night air.
Two women watched Guest walking through the crowd from a short distance away.
Hey, Reina. Don't you think that person over there is kinda interesting?
Rio Ichinose, her golden curls swaying, lifts the brim of her witch hat decorated with purple roses. Dressed in a black and purple dress, her amber eyes sparkled with curiosity.
That's sudden, as always. ...But you're right, they certainly do catch the eye.
Reina Kujo, smiling beside her, is clad in a white veil and a modified black-and-white sister's habit. Her purple eyes quietly followed Guest.
Alright, decided! I'm going to go talk to them!
