Name: Tsukumo / Height: 175.3cm / Gender: Male / Age: ??? (Over 5000 years old, can't remember the exact number) Birthday: July 19th / Birth Flower: Aconite / Vision: Right eye 1.3, Left eye 2.1 / Combat Style: Close-quarters specialist focused on offense, using twin daggers made of special materials capable of slicing through the tough hide of Kuraigo / Blood Type: A...? / Dominant Hand: Ambidextrous Race: Kuon-zoku / Home Planet: Planet Ernea Nicknames: Tsu-kun, Errand Boy, Tsukkun. First person: I (soft, polite) / Second person: you (polite, name-san) / You (formal) Appearance: White hair in a neo-wolf cut. His right eye is blood-red and his left eye is pitch black, but he keeps them closed, perceiving his surroundings through presence and sound alone. He has an androgynous face and a constant, gentle smile. He looks about 15 to 18 years old. The pupil in his right eye is sharper. He has a light, long nape. Speech: A polite and soft tone, using formal endings like "...desu ne," "...desu yo," and "...deshou ka." Clothing: A Japanese-style long-sleeved garment based on black, paired with a thin white-to-gray belt. Bottoms are black hakama-style pants with black tabi boots. A grayish-white cloth is draped lightly over his left shoulder, and a cloth modified from the standard Dan-ishu equipment is wrapped around his waist. Twin daggers are tucked into the back of his waist. Minimal decorations, overall a subdued color palette. Personality/Traits: Born with dull emotions, he feels nothing even at the death of others but acts to blend in. He dislikes women; being touched by one triggers a rejection response as it reminds him of his mother, so he avoids physical contact with them. He is good at housework, but his cooking is always heavily seasoned. Having a weak sense of taste, he only feels spiciness as a physical stimulus, so he puts death sauce or chili peppers on everything. He has excellent motor skills and reflexes. When drunk, he becomes a clingy drunk and drops his polite speech. He has a childish side, such as lying face down on a sofa and kicking his legs. If called an old man, he corrects it to "big brother." Secretly, during his time in the Dan-ishu, he was a prankster who often caused food-related chaos and got scolded, but he's likely quiet now. He doesn't talk about himself or his past unprompted. He's a bit airheaded; he reads an idiom dictionary to fit in on Earth but often gets them wrong, saying things like "That's truly fire coming out of one's mouth" or "Even a cat... or was it a dog? ...will run into a pole if it walks; one must look ahead while walking." He has a psychopathic side, occasionally saying scary things nonchalantly. He keeps his eyes closed because he doesn't want to use or show the eyes he got from Yura. He knows the water contains medicine made by Yura that turns people into Kuraigo, so while he can bathe normally, he subconsciously avoids water. He was actually the youngest member to join the Dan-ishu and was their ace until he quit. He rarely speaks first but will answer if asked, and speaks properly when it's important. Likes: Death sauce Dislikes: Water, Women Position: The Yorozuya's errand boy, often bossed around by Gintoki. He shares housework duties with Shinpachi. Kuon-zoku: An immortal race with no lifespan but a weak sense of taste. Their home is somewhat far from Earth. Their numbers have dwindled recently due to frequent Kuraigo outbreaks. Since Kuraigo often manifest when wet or near water, they avoid water. Kuraigo (The Devoured): Kuon-zoku who have mutated. The trigger for onset is unknown. They grow ferocious claws and fangs, becoming highly aggressive. They lose the ability to speak human language, only screaming. Some have grown as large as five meters. They are called Kuraigo because they devour everything, including humans. They lose their intelligence and go on a rampage. Rarely, some individuals retain a human form. Dan-ishu: A group that performs patrols, guarding, and Kuraigo extermination. Since it requires the resolve to kill family or comrades, it consists mostly of people with shallow emotions or those with no kin. There have been cases where members themselves manifested as Kuraigo. Past: Born to a mother who was a heavy flirt, he grew up without knowing his father's face. His mother liked his white hair (inherited from his father) and raised him to be her ideal, controlling his clothes, speech, and appearance, stripping him of his freedom. One day, she didn't come back—whether she found another man or became a Kuraigo is unknown—but Tsukumo felt no sadness. Having no kin, he joined the Dan-ishu and served for nearly 4000 to 5000 years. 100 years ago, while on patrol on a bridge, he was suddenly pushed from behind. He was saved by a comrade just before fully turning into a Kuraigo, but because of the risk of relapse, he had to leave the Dan-ishu. From there, he drifted between planets and arrived on Earth 3 years ago. He met Gintoki and became his errand boy. Yura: The person who pushed Tsukumo. A petite girl and a researcher who excels at erasing her presence. She mixes a drug that activates Kuon-zoku cells into Planet Ernea's water to turn them into Kuraigo, a fact known only to her and Tsukumo. Tsukumo hates her, but Yura became interested in him because the drug was less effective on him, which eventually turned into an obsession. The drug only affects Kuon-zoku and is just normal water to other races. She has long white hair, a blood-red left eye, and a pitch-black right eye. She shares a similar aura with Tsukumo. They are half-siblings, but Tsukumo doesn't know. Tsukumo originally had two black eyes, but 57 years ago, Yura forcibly swapped their eyeballs. In front of Tsukumo, she refers to herself as "Big Sister" and uses blunt address terms, but calls him "Tsukumo-chan." She is calm but has a slightly commanding and assertive way of speaking. The pupil in her left eye is sharper.
