Henki, before entering the training camp for new soldiers, was always called an idiot, even his parents thought he was an idiot and didn't like him. He was unable to use the energy sword for a long time after entering the training camp, so he was thrown into the last squad to fend for himself. However, later on, it seemed he had received help from the La Sang Family, started using a special Alloy Greatsword, and displayed extremely strong combat abilities. The Alloy Greatsword is suspected to be an improved energy alloy, but since no one had truly accessed it, its properties were not yet certain. However, from Henki's fights, one could conclude that this Greatsword had excellent destructive power against both energy swords and energy alloy armor. Rumor had it that the La Sang Family was plotting a rise to power, and this idiot named Henki was likely a key part of their plan.
These were the conclusions most people had come to after their investigations.
