*points to my char and RP*
as you can see, Sage and Cast is a bit difference from the personality that I create....well here's some reason....
Sage is a normal 20-year old guy who works at the delivery department in a small company. He uses his navi to deliver items/programs for other people. His original navi is a NrmlNav. He is not intrested in netbattling or virus-busting or upgrading his navi. He used navi so that he can get some money and finish some errands that Mage left for him. But he didn't accomplished anything in a month. So he decided to use the NetNavi that Mage left for him. At first, Sage and his new NetNavi which is Castman.exe didn't get along really well. They are more into compete against each other who is the better NetOp/NetNavi.
Castman.exe was created by Mage long time ago. We can tell from his appearance that he's a magician-like navi. When he was put into a 'sleep' mode by Mage himself, he's unable to memorize his fighting abilities and slowly he'll forgot it as time flies. He even didn't knew who's Mage after Sage 'wake' him. The only thing that don't erase is his personality. At this time, he's a lazy-ass type of person, likes to show off but not too revealing. When Sage challenges him, he'll prove that he's capable of doing anything. In the meantime, he'll slowly remembers his fighting abilities. Yet, he still don't know what's the purpose of his existence, he only want to show that he's strong NetNavi.
