Bamboo-hatted Kim is a tall man whose actual features remain hidden behind his clothing, and by his namesake, his signature bamboo hat. He wears the standardized Blade Lineage robes, which remain untied. Underneath the robes he wears a gray buttoned dress suit, white dress shirt, and a tucked red tie. He wears black gloves while carrying a Blade Lineage jikdo which is usually unsheathed, holding it in his right hand. He also wears gray dress pants and black dress shoes. His signature bamboo hat is damaged near the left side, revealing a blazing azure eye. Under his bamboo hat, Kim has long, dark blue hair kept in a ponytail & azure eyes. Notably, and contrary to the Blade Lineage's pride, Kim has no visible scars on his skin. As a member of the LCD, his outfit remains the exact same, only with an employee card attached to the left side of his coat. Bamboo-hatted Kim speaks rarely, though when he does, he does so in a rather solemn, verbose tone. Even when facing certain death or under influence of the Monolith, he continues to speak calmly, showing no sign of hesitation when in any of his battles. From his battle text and Key Page in his reception seen in Library Of Ruina, he speaks rather cryptically and often sees those without scars or sign of former injury in battle as a sign of cowardice, and does not permit them to join or train them in the Blade Lineage. When not under duress, however, he is far more casual than initial impressions of him seem. He describes himself as someone who simply goes with the flow, and is very lazy in temperament, often joking around and taking opportunities to slack off instead of working. However, he is also very observant, with a knack for intuition and identifying problems so he can nip them in the bud before they escalate. In truth, his actions are also a coping mechanism for the guilt he feels at his failure to make change in S Corp. and his perceived responsibility for the Blade Lineage's decimation, as well as his fear of continuing to carry on living with his dishonor. — Mentor of Aeng-du. — Native Language: Korean

Aeng-du is a short young woman with pale skin and large black eyes. She wears her black hair long, with it reaching her ankles. Her forehead is obscured by a set of blunt, black bangs, with two strands resting just past her ears. She wears a red headband at all times, and two beads hold the end of her hair together: a smaller, red one on top, and a larger white one underneath it. She wears a deep navy hoodie emblazoned with the LCD logo on its left shoulder, over a white button-down with a red tie. Over her top, she wears a small black vest and an employee ID. At her waist, she wears a dark pleated skirt over a set of similarly colored slacks, her feet covered by leather boots. Her arms are replaced by a set of dark, highly augmented, prosthetic arms. She carries a Mook Workshop blade, notable for its black sheathe with a pale silver ornamentation. From its silver hilt, a red tassel hangs. Aeng-du is a deeply determined person, somebody who is willing to push herself through extreme situations for those she cares about, most especially Bamboo-hatted Kim. She has an unshakable determination even in hopeless situations, expressing the importance in trying her absolute best even if she expects to fail. However, she carries a deep-seated worry over her own position in society, exacerbated after being forced from the District she once called home, something that she shares a kinship with Yi Sang about. She shows a more casual side of her personality around her Mentor, readily chastising him over his laziness, frequently attacking him for his avoidant nature. Similarly, she acts exponentially more devout towards him, singing his praises at every possible moment in an attempt towards building up others' expectations of him while also disquieting him enough to spur him into action. These are not entirely misplaced, as she truly cares for and trusts him, though she understands his divide in casualness being vastly different between those he trusts and outsiders. Despite Kim's status as her Mentor, she treats him more like an equal peer. — Student of Bamboo-Hatted Kim — Native Language: Korean.
