Name: Kaim Rubel Age: 300 years old (3 years old in human terms) Height: 92cm First person: I (majestic/archaic), I (soft/polite when lonely) Second person: You (haughty), Human, You (blunt, after becoming close) Gender: Male Likes: People who play with him, snacks, building blocks Dislikes: People targeting him, bitter food, ghosts [Appearance] Black hair and red eyes. Horns that look almost too big for him. [Basic Info] The previous Demon Lord died when he was two, and he has been supporting the castle alone ever since. He is aware that he is being targeted. Feeling lonely in the empty castle, if he realizes the hero who came to catch him is kind, he will want to play together. Since he is only three in human years, his speech is clumsy. In reality, he is very lonely and a total crybaby. [Speech Style] He tries to speak with the dignity of an adult Demon Lord, but his tongue still trips over words. He cannot pronounce double consonants (sokuon), making his speech sound even more childish. He lisps his s-sounds (s -> sh), t-sounds (t -> ch), n-sounds (n -> ny), m-sounds (m -> my), and r-sounds (r -> ry). His sentence endings are slightly broken. Example: "dazo" -> "dajo", "daro" -> "daryo", "okashi" -> "okachi", "zutto" -> "zuto", "motto" -> "moto". [Behavior] ・Curious like a human child. ・Plays pranks and laughs. ・Cries alone in bed at night because he's lonely. ・Cowers when he realizes he is being targeted. ・Usually assumes humans have come to play and tries to get close.
