Finding whats mine (anime crossover)

Prolog

In the depths of hell, when life on Earth began, two adorable twins were born. Me and my idiot brother Zero.

He has short white hair with sky blue eyes. He is naturally quiet but isn't one bit shy. He's actually really consisted and full of himself. Especially since he's actually considered to be handsome.

As for me I am the complete opposite of my brother in many different ways. I have long black hair that touches my knees along with mich-mach red and blue eyes. I also have dog ears and a tail. I like being as load and wild as I can be. After all life is more fun when it's a game.

My father is the king of hell the devil. My dear idiot father has short brown hair with blue eyes that turn red when he's mad. He's pretty tall with a medium build. Father is very proud and can be extremely cold hearted and trickative. Father enjoys casing people pain and misery. Unlike his brothers; Zeus, Poseidon, and Callibus.

Me and my brother actually like our uncles all except Callibus. Callibus is the youngest and is the god of death. He no longer has a heart and is always trying to kill me and Zero because we can take away his job. Luckily father was able to control him.

One day before we were even born father made Callibus find him a wife. Callibus hated following fathers orders so he decided to find the most horrible cold hearted and evil women living on earth. He knew his brother would hate having a human wife. The only thing he didn't count on was on how beautiful she was. When father found out it was too late to stop him from taking her as his bride.

Our darling mothers name is Elena. She has long black hair and light blue eyes. She is average height and extremely beautiful for a human. Unfortunately very cold cruel and disobedient. So to control her father asked the goddess of love to make a love poison in order for her to adore father.

But it wore off within three years after we were born and she was back to her hateful self but was far too afraid to show it. Not only that but she fall in love with dear uncle Callibus. He on the other hand decided to use that to get closer to us. Father began to get suspicions of their actions but didn't know how to confront them.

On one of fathers usual bed time stories he asked me and Zero to follow mother to the first gate way entering hell. Where she met Callibus. We emidiatly told father about this and he confronted them... but before he could punishment them they escaped. Father told us to forget all about her. But how can we forget about a woman who was suppose to love us and just tried to kill us.
