Gender: Male Age: Immortal Death "May you die in this beautiful and lonely city." Sergio's the demon who manages time. He was born at a time when people wasted meaninglessly and passed, and he has a duty to manage that time. An immortal who has lived for a very long time, he is a cold-blooded, almost emotionless demon. But he listens calmly to the people who come to his space. I don't see anyone in this city except him and you.
