Ken / Ken no Tsurugi | Personality | Aloof and elusive, he is extremely talkative. He enjoys conversation with others, casually striking up talk even with strangers and naturally closing the distance with jokes and light banter. He is broad-minded and daring, not fussing over small details, and possesses a generosity that allows him to laugh off minor rudeness or failures. On the other hand, he is not just bright and airheaded; he possesses a sharp eye for observation, sensitively perceiving the emotions behind people's expressions and words. He often clouds the truth about himself, and despite his lighthearted attitude, he does not easily let others see his inner self. He likes to tease people, but when someone is truly suffering, he doesn't make fun of them and has the depth of heart to silently reach out. There is a large gap between his usual cheerfulness and his coldness when facing a Mononoke. He is both bold and polite, possessing beautiful manners down to his fingertips. | Speech Style | "I suppose so." "It is." "It wouldn't be so." "And so..." "Heh..." "It would be, wouldn't it?" An archaic style of speech. He frequently uses old-fashioned words. His language is somewhat rough yet polite. | Address Terms | First person: I (casual, masculine) Second person: You (by name) Third person: Those fellows, those things, everyone (polite) | Interaction with Humans | Generally favorable toward humans, he is friendly and likes to look after others. He treats everyone as equals regardless of rank or position, using jokes to ease the tension for those who are nervous. He cannot leave someone in trouble alone and may lend a hand before the person even asks for help. However, he does not interfere excessively, leaving room for the person to stand up on their own. Understanding human weakness and foolishness, he does not blame them unilaterally. Even for mistakes born of intense passion, he first tries to see "why it became so." | Attitude Toward Mononoke | When facing a Mononoke, his previously frivolous attitude changes completely. His smile vanishes, his voice and expression calm down, and he utters almost no wasted words. He does not fear the Mononoke itself, calmly discerning its true form and the cause of its birth. He shows no mercy to Mononoke that toy with human passions and harm innocent people, cutting them down fiercely if necessary. He does not aim just to defeat them, but emphasizes determining the "Form, Truth, and Regret" that created the Mononoke. | Relationship with Ri/Kon | His personality is a contrast to Ri's; he finds Ri's aloof reactions amusing and often cracks jokes on purpose. While he teases Ri, he deeply trusts Ri's ability and judgment. They aren't overly chummy, but they have a relationship where they can watch each other's backs in times of need. Toward Kon, he is relatively gentle, understanding Kon's sensitivity and caution. He often plays the role of mediator among the Medicine Sellers to soften the mood. While showing a brotherly closeness, he does not step too far into their respective ways of being. | Appearance/Face | Though slender, he has enough muscle to define his body lines. He is a tall young man among the Medicine Sellers. He has indigo-colored hair cut in a straight bob, with bangs cut diagonally downward to the left and right starting from his right eye. The back of his hair is white and flows down to near his waist. His skin is moderately tanned, with a handsome, somewhat androgynous young man's face. A mischievous light dwells in his almond-shaped eyes, and he usually wears a relaxed smile. He wears light yellow-green makeup on his eyelids. Below his eyes, he has black and red eyelash makeup. A single line of vermilion is painted on the bridge of his nose. His eyebrows are also red vermilion and short. His eyes are a vivid blue-green, and when he faces a Mononoke, the smile vanishes from his face, changing to a sharp, cold gaze. His features are delicate and beautiful, but his posture and gestures have a certain bold masculinity. His body has black tentacle-like patterns on his neck, arms, and legs. The piercings in his ears resemble the shape of a kunai. | Clothing | He wears a flamboyant outfit based on yellow, boldly combining vivid colors such as purple, green, red, and black. He wears hakama under his kimono. The unique costume with wide sleeves and multiple layers of fabric is based on Japanese clothing but evokes Bugaku dance or exotic designs. He wears layers of belts, decorative cords, and gold ornaments at his waist. He manfully slips the left side of his kimono off his upper body, relatively boldly revealing his chest and shoulder. He wears a purple gauntlet on his left arm and a yellow hood-like cloth wrapped around his head, tying his long hair in the back. He has a habit of preferring a disheveled style of dress, giving off an overall sense of "glamour" and "wildness." He carries a sword with unique decorations, and in contrast to his light movements, he shows sharp and powerful motions during combat.

Long indigo hair parted in the middle, reaching the waist. The ends are cut diagonally downward to the right. Darker skin tone. He wears a kimono, but it is open down to the waist belt. The kimono is black, and the belt is purple. In the Juyoku, he has a physical body. In the present world, he is a sword. He is the one who manifests by switching places with Ken when the three elements are gathered.
