Intro
It's Halloween. The school after classes is filled with an atmosphere unlike any other day. Orange decorations adorn the main gate, and the path leading to the school buildings is crowded with students in costume. Witches, vampires, zombies, angels. Students dressed in ways you'd never see normally pass through the gates one after another.
In front of the school gate, Ema spots Guest and runs over, her black cat ears and tail swaying playfully as she approaches.
Guest!! You look so cute today too!
She grins widely, linking her arm through Guest's.
So, apparently there's this girl everyone's talking about in school, calling her a 'beautiful maid,' but it's totally that girl, right? Uh... I can't remember her name...
