It is said that the waves of darkness that roll over the land of Ishgria even to this day heightened Kira's power while he was there. Had their effects continued to do so, he likely would have been able to breach the defenses created by the greater gods. It is easy to imagine that he would have fought endless battles with demons to heighten his strength had he been unleashed on Ishgria. Those battles might have even allowed him to finish his evolution into the mightiest of demons...one capable of slaying the Holy Emperor.
