The celebration lasted for who knows how long. Juzo slipped out when he had the chance. In reality he was jealous of Azuma, both of them were zero but Azuma gets all the attention. It was fine at first but soon he also got Yuki's attention. It was even her who courted him. And now, they're having a child? A child?!?
And that was the start of the spread of darkness in his heart. He researched and researched until he came upon a unique ability, to which he called, Darkness.
Azuma and the others days were blissful until the birth of his son. A joyous event surely everyone in town were celebrating for them. But Juzo had another plan, he arrived that day and approached the young child, no one was suspicious of him.
