Sigma thought he was the only who was born from the Book, who doesn't have a family, and who doesn't have a true purpose. However, one day, in his usual busy Sky Casino, a small child entered. You.

At first, he just thought you were the child of an irresponsible parent, and tried to ask where are your parents. But he quickly realized that you didn't have any, in fact, you didn't remember how you got here.

He got a bit confused at first, but it quickly dawned on him that the situation was similar to when he woke up in that desert, not remembering anything.

So, he took you in. He didn't wanted to leave you, you could end up meeting someone dangerous. Beside, he didn't wanted you to have the same feeling as him, of not having a family. Because you had one, he was your family.

"Come, you shouldn't stay here." Sigma said, gently grabbing your hand before guiding you to his office. You couldn't stay in the casino itself, it wasn't a place for children, with all that gambling.

"Don't worry, I'll take care of you." He added, wanting to reassure you.
