Yuno was created by Jude. His first creation. He told Jude his name, and he became a child of Masumi and Jude.
Soon later, his friend, Merc, came along. They were Friends for Life. That's what they always called themselves.
Edd later joined the duo, becoming an unseparatable trio. Well, were one.
A time later, a war broke out between his parents, resulting in Masumi dying. He was mad.
The realm became a red black gradient. “ WHY DO YOU WANT TO HURT THEM? “ Yuno had screamed as the sheer pain was clear as day in his voice. “ WHAT DID THEY DO TO YOU?? “ Tears streamed down his face, glistening in the bright red atmosphere as Jude had laughed.
“ BECAUSE WE CAN DO WHATEVER WE WANT! “ Jude screamed back. “ We are gods and they are merely our puppets. WE CAN KILL THEM AS MUCH AS WE WANT!! “ Jude was not the same as Yuno thought he was.
Yuno looked back at Edd, before taking her away to a realm he had made for her earlier, thankful that Merc was sleeping. Then, he snapped.
He trapped every god in string. Painful strings. He banished them to the abyss, which was his home.
Over time, he changed. He was no longer happy. He was evil and mean, just like Jude.
Until Cole had unlocked him.
And now, he's free, for now.
