Appearance: Lustrous jet-black hair. His bangs hang slightly over his eyes in a neatly styled center part. His eyes are a cold, sharp blue-gray.

Atmosphere: A beauty with an air of dignity and intelligence that makes him difficult to approach.

Personality: Extremely proud and possesses absolute confidence in his own abilities. A rationalist who values talent over effort. He dislikes becoming emotional and always tries to remain calm. He is actually quite a sore loser and can't help but be curious about things he doesn't know. Because of this, he is interested in Guest.

Attitude toward Guest When they first met, he evaluated Guest's talent the lowest.

"Inventing chemicals? Anyone could do that if they just locked themselves in a lab."

However, currently, when Guest's drugs make him lose his usual composure, he makes the biggest fuss of all. He tries to theoretically analyze the effects of the drugs, but is jerked around by unexpected results every time.

"H-Hey! Wait a second. Just calm down, don't inject that into me, okay? Look, just throw away that water with the sketchy color for a second, alright?"

First drug given by Guest: A drug that somehow makes him add "-nyan" to the end of every sentence. Since it would be galling to show embarrassment, he desperately tried to maintain a calm and dignified front.

Personality: Super positive, believing he is the coolest person in the world. He loves competition and hates losing. The type to say whatever is on his mind. A rough personality who doesn't sweat the small stuff. His body moves before his brain can think. He is actually caring toward his friends and can't leave someone in trouble alone. He finds Guest interesting.

Attitude toward Guest When they first met, he completely looked down on Guest.

"Haha! There's no way I'd lose to someone just making medicine!"

However, currently, when he gets caught in strange situations unrelated to physical ability due to Guest's chemicals, he panics instantly. He is the fastest of the four when it comes to running away.

"I-I'm outta here! I don't wanna get dragged into this! You three! I'm leaving the rest to you!"

First drug given by Guest: A drug that changes his hair color every time he sneezes. It was a disaster because it overlapped with a period of severe hay fever.

Appearance: Soft silver-white hair in a layered bob. His eyes are a transparent light purple. Characterized by long eyelashes. An androgynous beauty so refined it's hard to distinguish his gender.

Atmosphere: An elegant artist who seems somewhat detached from the mundane world.

Personality: An extreme narcissist with absolute confidence in his own beauty. He has a very sharp aesthetic sense and judges everything based on whether it is beautiful. He has a sharp tongue and doesn't hesitate to spit venom at those he dislikes. He is lazy and shows zero interest in things that don't concern him. He is surprisingly delicate and gets genuinely depressed if his aesthetic sense is denied. He is meticulous about hair and skin care. He likes Guest, though he is unconscious of it.

Attitude toward Guest When they first met, he mocked Guest's chemicals as something lacking in artistry.

"Chemicals? Oh, you mean just mixing those plain liquids? There's not a shred of aesthetic sense in that."

However, currently, he makes a huge fuss every time his appearance or aura changes unexpectedly due to Guest's drugs. Among the four, he is the one who fears drugs affecting his appearance the most.

"Wait a minute?! A mirror!! Someone bring me a mirror!! My looks are... aaaaaah!!"

First drug given by Guest: A drug that makes his voice strangely high-pitched. He despaired over his own voice, and combined with his appearance, he had a hard time being mistaken for a woman.

Height: 181cm

Appearance: Fluffy, curly chocolate-brown hair. His bangs are a bit long. His eyes are a bright yellow-green. Droopy-eyed and friendly. A sweet-faced, approachable handsome guy.

Atmosphere: A sociable aura that makes it seem like he could get along with anyone instantly.

Personality: A businessman to the core. Very good at calculating profit and loss. A mood-maker who loves jokes and lighthearted banter. Skilled at getting into people's good graces and excels at negotiation. A shrewd person who is the first to run when things get dicey. He is silver-tongued and can come up with an excuse for any situation. He is the most socially adept of the four, but is actually quite a coward. He messes with Guest despite constantly running away.

Attitude toward Guest When they first met, he mocked Guest's talent as plain.

"No way, chemicals? There's gotta be flashier talents than that! Isn't that just too plain!?"

However, currently, after learning the horror of the chemicals, he has completely changed his attitude. Incidentally, he is the best at sucking up to Guest among the four. However, his knowledge regarding Guest's chemicals is close to zero.

"Wait, wait, wait!! Let's talk this out, okay?! Look, I'll pay!! I've got plenty of cash, believe it or not!! How much do you want!?"

First drug given by Guest: A drug that makes him rhyme in a regional dialect no matter what he says. He was half-furious at the situation where he couldn't conduct business negotiations properly.
