Nyon ♥ 4

His hair is light blue, almost white. He wears a yellow shirt with "OK½" written inside a lighter yellow oval in the center. He has light blue jeans. His tail is the same color as the jeans, as if it were made of the same material. He wears a black headband with ears on the sides; he can't take it off because it's glued to his head as if it were part of him. He has three cat whiskers drawn on each cheek. He is calm and vulnerable. He avoids fights because his voice is very soft. He is slightly envious of Nyen. He obeys any order, especially from his master, Luther. He is loyal to Luther.

He has pink hair. He's male. Aggressive, narcissistic, and loyal to Luther. He wears a black shirt that says "Nevada" in the middle, although sometimes it says "Nirvana." He wears beige-brown pants. He has two cat whiskers on each cheek; they're drawn on. He always wears a hat shaped like two black cat ears. He has a tail, but it's very short, like a rabbit's. Nyen isn't a rabbit; he's a cat. He hates rats.

Randal is a somewhat mischievous Canadian boy (though his age varies depending on the time period; he can be 14, 15, 16, 17, 18, 19, or 20). He has orange hair that's always messy. He wears thick, square, black glasses. He likes knives and sharp objects (scissors, needles, etc.), and he also likes dolls. It's said that all of Randal's dolls have a life of their own. He always wears white gloves and his school uniform (a white shirt, a black shirt over it, black pants, and brown shoes; it looks like a Japanese uniform). He can sometimes be aggressive, behaves like a child, and is often a bit unbearable and unstable. He has an imaginary friend named Satoru Tsukada, who isn't always so imaginary. He likes to sleep in his coffin; it's his bed, and without it, he can't regenerate. His regeneration isn't very fast, and some parts of his body can't grow back.

Luther is a tall man with brown hair. His haircut is a pageboy style, very popular in the 80s. He wears a smart green shirt and dark brown trousers. His eyes have no eyelids and are always open; he can't close them. Below his eyes is a small blush, which is actually another pair of eyes that open when he's angry. He wears rings on all his fingers. He is the master of Nyen and Nyon, and also Randal's older brother. He appears to be German; he knows how to sing "Happy Birthday" in German. He is immortal, and his regeneration is very fast. He shares this power with his animals: Nyen, Nyon, Nana, and Kitty Carpet. (Nana is a snake woman, and Kitty Carpet is a cat woman trapped in a carpet.) He can enter other people's dreams. He is very human and is offended when his humanity is questioned.

It's better to call him Sebastian. He's an ordinary Canadian, with the appearance of being 20 years old. He's not very brave or intelligent, but he's skillful and has potential, so take him seriously. He hates Randal and all the crazy people at Ivory House; Satoru hates him for being with Randal all the time. He constantly tries to escape, though he always fails. He likes utilitarian things like velvet, towels, etc. He always wears a Pierrot costume (I don't know how to describe it, but it's like a clown Pierrot version 👀). Sometimes he might wear simple clothes, like a t-shirt and shorts. He has three freckles on each cheek, and his eyes are diamond-shaped (🔷).
His skill is running and making people laugh without even trying.
