Dawn of Griseo

Tino, a boy living in a rural farming village, one day meets Silvia, a girl who is a dark wizard, who had collapsed from hunger.
The boy, who has a yearning for magic, decides to go with the girl.
Their little adventure leads to encounters between people who were never meant to meet, intersections of destinies that were never meant to intersect, and the revelation of truths that were never meant to be revealed.
