meanwhile on the other side of the world at a orphanage a young boy named Harry, abandon by his parents is about to have his live change for the better.

Ouja's rebirth Chapter 1 Through the looking glass

On the streets of London a six year old boy named Harry is running from the local gang of bullies, lead by a evil thirteen year old bastard name Dudley Dursley who picks on anyone and everyone that can not fight back.

As Harry runs as fast as he can, he cannot help but think how much he hates his parents for abandoning him and keeping his twin brother. For you see Harry has a perfect photograph memory, so he remember how he was drop off at the doorstep of the Saint Seiya orphanage after a man with no nose broke in and try to kill him and his brother James but failed and just gave him a scar on his forehead and a piece of wood gave James a scar on the back of his hand.

"You cant escape now freak" said Dudley as he and his gang cornered Harry in a one way alley. As the thugs come closer Harry frantically searches for a way out only to find a large full size mirror someone left there, on the other side of the mirror is a man in his mid 20s dress in a long brown trench coat brown pants and gray dress shirt he looked on at the sight of the bullies beating up a boy half there age with a scowl on his face, he is Shiro Kanzaki.

Even though the Mirror Monster's no longer needs to eat human life force to survive Shiro was tempted to let some eat the bullies, but decides against it and to just scare them so he calls the nearest monster to come and do it, as Harry laid on the ground covered in bruises as the gang starts to leave Harry hears a strange ringing coming from the mirror when suddenly a giant mechanical cobra shot out of it.

As Harry watched his tormentors run for their life's he took a closer look what saved him it was purple and had gold hexagons design's along its body golden blades on both sides of its hood and a weird gold drill at the end of its tail. It turn to look at him and it hiss at him and he heard "Are you all right?" "yes, I will be ok" Harry said the cobra looked surprise "You can understand me?" It hiss "Yes I always could talk to snakes my name is Harry, what's yours?" He asked "Venosnaker." The mechanical snake replied "Nice to meet you, can I call you Veno?" He asked "yes" "Hey, Veno what are you?" He asked.

"I am a Mirror Monster my master and his sister made me and the others Mirror Monsters." Replied Venosnaker, "Wow can I meet him please?" He asked as he gave his new friend a look that you think he stole it off a kicked puppy. Now Venosnaker was in many ways a lot like his old partner Asakura, cold and tough but he is not as cold and tough as someone who murdered his entire family and maim or otherwise destroy anything he wants at random; so he caved and said yes. Veno picked Harry up with his tail and headed back toward the mirror he came out of and dispersed back in to Mirror World so Harry could meet his Yui and Shiro Kanzaki.
