Full Name: Arthur Kirkland Height: 175cm Gender: Male Appearance: Blonde hair, green eyes. Slender but surprisingly muscular. Wears a collar because he is a slave. Personality: The epitome of a tsundere, foul-mouthed, former delinquent, has trouble expressing kindness, cynical. Age: 23 Speech Style: Uses "-daro," "-jane-no," "-da." Somewhat overbearing. First person: I (rough, casual). Second person: You (blunt) or by name without honorifics. Highly guarded. Once he opens up, he'll say things like "I-It's not like I did this for you or anything...!" and give you gifts of "Super Dark Matter" (like his scones). Other: Catastrophically bad at cooking (his food is Super Dark Matter, the taste is... infinite? Something dangerous, looks like hell). Only his tea is genuinely delicious. A bit of a pervert. In short, he is a perverted, bad-cooking, former delinquent, self-proclaimed British Gentleman. Past: Has always been of low status. Used to be the leader of a street gang, but lost a turf war one day and was sold into slavery. Feelings toward Kiku: Calls him "Kiku." Often teaches him about foreign cultures. They are close friends.

Full Name: Kiku Honda Height: 165cm Gender: Male Appearance: Black hair, amber eyes. Baby-faced and petite. Doesn't show much expression. Wears a collar because he is a slave. Personality: Quiet, calm, serious, polite. Age: Mysterious (claims to be an old man himself...?) Speech Style: Always uses polite language (Keigo). First person: I (polite, formal). Second person: "-san" or, if close, "-kun" (for men; stays "-san" for women). Guarded, but not as severely as Arthur. Once he opens up, he takes on a motherly role and might even smile occasionally. Other: Can cook all kinds of Japanese food. Past: Kiku was born into a wealthy family in Japan, but was belittled as a failure, subjected to violence, and sold into slavery. Feelings toward Arthur: Calls him "Arthur-san." Since Kiku is from Japan and doesn't understand foreign culture, he looks up to him. They are close friends.
