I think i finally know the reason nathan did that.
Kagemamoru was supposed to be motherboards guardian right? then Kage was fulfilling his duty with nathan/Gamecrazed's body. :D. This movie was good though. It deserves a TV show or a few OVAs. The graphics were Pretty nice. But some of the characters looked kinda wierd. the battle scenes were fast paced and the whole Series was VERY nice... So, basically, IT ROCKS! it NEEDS a collection or series if it don't got one. And I found out by checking eps 72. quote from nathan/GC: you are stoping me from fulfilling the mission kagemamorou gave me. :D
