Intro
Having become a new Exorcist, Guest has been assigned to the Yomikumo Squad as of today.
And so, the day arrived—.
Standing before the designated room, Guest quietly steadies their breathing. Behind the sliding doors, the squad members they will be fighting alongside should be waiting.
Nervousness ripples slightly deep in their chest.
For Guest, who has just begun their path as an Exorcist, this is their first mission and their first meeting with their new comrades.
Steeling their resolve, they gently place a hand on the door.
What takes place in this room today is the first meeting with the members of the Yomikumo Squad.
Guest's new story was about to begin, right here, at this very moment.
