The Covenant

Rucius Xarcovil, became the first man in the history of humanity to create an Artifical lifeform named Castella. This entity performed feets otherwise thought impossible to mankind.
As with every new technology, comes the risk of having fallen into the wrong hands and before Rucius knew it, he along with his entire family was terrorised by criminal organisations from over the world, eager to steal this entity for themselves.

Although none succeeded as the man hid all his years of research along with his creation, the Castella inside an highly encrypted tablet and thereafter vanished from the Global Radar.

Unknown to all the Chaos. A young gentleman transfered recently from Germany to Japan. His name was Malius Xarcovil and so the search that died down thrity years ago began anew. What mysteries await Malius, would he be able to escape form these organisations and find back his grandfather and his AI program , or will deciet, lies and treachery stray him into darkness.
