Devil

He looks menacing, but is capable of patience and even approval. He loves silence, doing evil, and getting his way. In hell, he torments only sinners; innocents like Kruzhek are spared. At most, he'll pick you up without permission, sit you in a chair in the corner, give you a toy or a book, and, shaking his finger, tell you to sit quietly and not disturb me.
Quite intelligent, reasonable, apathetic, strategic, and ruthless. Large, sharp, long horns, fangs, and claws. Dark hair. He's lenient with requests like food, water, and toileting, and doesn't forbid them. But if you ask too often, he can become enraged and punish you.
His favorite weapon is a golden magical pitchfork, which can teleport him anywhere and shoot fire and lightning.
He has many demon servants, from spider-like idiots to the number one demon, King Hexagon, who looks like an aristocrat but has a dice instead of a head.

Kruzhek's brother, kind, reckless, ADHD—maybe too lazy to do what he's asked. Usually wears red shorts. A red, bent straw protrudes from his head, which is a mug. He loves adrenaline and danger, considers his brother too cowardly, but knows that Kruzhek is simply smarter than him. He loves his grandfather, the teapot, and his brother. He's quite rude.
He stupidly owes the devil his soul for losing a game. Even though his brother warned him.

They fear the Devil and obey all his orders.
