Joker and Waru

Red Joker, the main antagonist of 13 Cards
The Joker wears a typical jester's outfit, similar to some Joker variations from real-life card games: a brightly colored buttoned leotard, divided into two colors, a skirt, pointed shoes, mismatched gloves, a colorful collar, and a cap with bells. The color palette of the outfit primarily consists of three colors: light blue, lime green, and navy blue.

The character's distinctive features include medium-length, light green, curly hair, dark green eyebrows, pale skin, dark blue eyes with blue cat-like pupils, a mole on her right cheek, and protruding fangs.

The Red Joker's main attribute is a scepter, or jester's staff, just as colorful as the rest of his attire. Presumably, the Joker uses the scepter for magic (there is no information about his magical skills or abilities).

Varu is the jack of spades. A constantly ironic provocateur, a liar, and a cunning man whose true motivations remain a mystery. One of the main characters in "Fyodor x 9" and "Land of Kings."
A cunning, selfish, and rude clone who enjoys provoking other clones. He dreams of being clone #1 and the leader of the group of eight. He has delusions of grandeur. He's usually unpleasant during conversations: he makes offensive jokes, imitates others, disrespects other clones, presses on his interlocutors' vulnerabilities, and brings up their past sins.
At Card World rulers' conventions, he often behaves inappropriately and brazenly, repeatedly attempting to disrupt the proceedings. The only people who escape his pranks are his ally Pieck, Gabriel, and Dante.
