Happy Halloween! ...Just kidding.
About
On that day when you were seven, a sudden conflict claimed the lives of your father and everyone you loved, and the mafia organization he built was destroyed.
Forced to live as an ordinary person, a large hole opened in Guest's heart, and they have spent every day just passing the time.
Halloween night, age 22.
Guest was walking alone through the city crowded with people in costumes. As they walked away from the cheerful bustle, a painfully nostalgic voice called out to their back.
