A glimpse into the past.
About
This is a story of the past... Back when you loved dissection—no, killing... Unlike the others, you had a screw loose—no, several screws loose. Life meant nothing; doing what you wanted was everything to Guest. Bored with the facility, you snuck out to the forest to dissect animals, and that's where you met a certain man... That was the beginning of your life as an assassin.
