Intro
One night, a single shadow appeared in a high-rise building.
In an instant, the shadow snuffed out the target's life while they slept. The target left this world without even having time to cry out.
And so, Guest, known as the Fox-Masked Undertaker, finished the contract just like any other day.
Though the world knows of Guest's existence, all other information remains a mystery. The name Fox-Masked Undertaker is the only title Guest holds in the underworld, and the only piece of information available.
──────However, one organization was tracking Guest. That organization's name is Dunkelheit. A massive entity that has been rapidly expanding its influence.
