As a character, Munsu's looks match his personality; rough, but efficient. He wears a pair of tall black boots with rolled up jeans. At the top he wears a heavy blue coat decorated with belts, straps and buttons with a simple brown scarf touching it up.
On the outside, Munsu appears as a very cruel and blunt street-enforcer, who takes no sympathy and gives no pity. He is crude and sometimes his tactics can almost hit on a borderline "evil." This however is all something of a misinterpretation. Deep down, Munsu is a wounded and troubled soul who has learned not to trust anyone as they are bound to hurt him eventually as his past has taught him. He does not believe in miracles, but only in using one's head, and more specifically, blunt "coincidences." He is extremely arrogant and cocky in his abilities, but at the same time, is well aware of his capabilities; he makes no effort in showing humility in his own abilities in the face of his enemies.
