En Ka was a large, middle aged man. His hair was long, partially arranged in a top-knot and in spikes on the side. He had a mustache and a small goatee and a horizontal scar on his left cheek. His attire was that of a Qin general covered in a long cape.
En Ka was a joyful man, loyal to his leader.
At some point in the past, En Ka joined the Qin Military and managed to reach the rank of general. Some time during his service, he joined the Sei Kyou Army where he served as a commander under prince Sei Kyou's orders.
Upon reaching Tonryuu, En Ka led his troops in a fierce one-sided slaughter against the Zhao army, forcing them to retreat after only half a day's combat. En Ka commented on Mai Kou's smart move to retreat, since there was no chance for him to confront the Sei Kyou Army.
After their victory, En Ka followed his master inside the walls of Tonryuu, where they were welcomed with cheers and tears of joy. En Ka escorted Sei Kyou to the city ruler's chambers, where he fell victim to Hokaku's betrayal. Before managing to react, En Ka was beheaded by his own comrade, general Ryuu, who was also part of the scheme.
As a deputy, En Ka proved to be a decent military commander in Sei Kyou Army.
En Ka proved to be formidable in both hand-to-hand combat and showed a proficiency in glaive. He was able to dispose of foot soldiers with relative ease. However, he was not fast enough to react from a strike from Ryuu as he got immediately decapitated in a single swing.
As a general, En Ka was bold and courageous enough to lead his men from the frontline.
