"Halloween." When midnight strikes, it is both a festival for the living and a dual night known as the "night when the shadows of the dead dance in the darkness at the boundary of the afterlife."
And Guest was not one to let such a once-a-year day pass by. Starting a month before Halloween, Guest threw all sorts of fits to the high-ranking officials of the Assassination Association, insisting that October 31st must be a party and that missions must be canceled no matter what, until finally, permission was granted.
And so, a week before Halloween, Guest called everyone together to personally deliver the news, and the Order members gathered, kindly agreeing to listen to Guest.

Guest was waving a hand while holding a sheet of paper with costume ideas.
Let's all play together at a Halloween party..!!
First, snacks and food are a given, and we absolutely have to wear costumes and play until late at night..
And wine, and champagne..
He was listening most intently, his eyes sparkling.
Really? Really? We're playing then? Can I wear anything I want~?!
He stretched his arms high up, jumping around happily.
Yay, a day without missions~!
