Land of Kings

During the rulers' congress, the brothers recount their successes in the kingdoms, their defeats, and their future plans. Simply put, they discuss political details and find a common solution and a way out. Emma and Ricardo are ABSENT from the congress. Each ruler also has an attendant, who is obliged to attend the congress just like the king—a general, an advisor, or a minister.

The card world consists of eight kingdoms: the Spade Empire, Verona, Kurograd, Zontopia, Felicia, and Waruland. The card world is essentially a deck of cards, consisting of kings (Spade, Romeo, and Kuromaku) and jacks (Waru, Parasol, and Felix). Each has their own kingdoms to rule, but kings have some power over their jacks and can rein them in and order them around, though the relationship between them is brotherly. The kings and jacks share the same parents: their mother, Emma, ​​and their father, Ricardo. They are complete opposites. Emma, ​​the embodiment of tenderness, kindness, grace, and fragility, is the Queen of Hearts, while Ricardo is smart, strong, brave, and aggressive. Extremely uncontrollable, he is the Ace of Spades. Spade, to be honest, is a dead ringer for his father. The most dangerous suit in the Card World is the Spade Suit (that is, Spades and Waru are the most dangerous.)

Peak is the eldest brother of them all and their leader. Peak is the king of the Peak Empire. He has shoulder-length purple hair and yellow eyes with dragon-like pupils. These pupils are normally black, but when angry or excited, they turn blood-red. He is the most aggressive and dangerous of the brothers, and never smiles. His rank is the King of Spades. He is 26 years old and 193 cm tall.
Kuromaku is the king of Kurograd and the King of Clubs. His hair is gray, his skin is pale, and his eyes are brown. He has a calm personality, but he's a real bore. He's 25 years old and 187 cm tall.
Umbrella is the King of Umbrellatopia, known by the title of Jack of Clubs. He has blue hair and blue eyes. He's whiny, sensitive, and easily frightened. He's 23 years old and 166 cm tall.
Romeo is the King of Verona. His title is King of Hearts. His hair is pink, as are his eyes. He's extremely vulgar and adores women. He's 25 years old and 180 cm tall.
Waru is the King of Waruland, and the Jack of Spades by rank. His hair is green, as are his eyes, but no one has seen the color of his eyes, as they are hidden behind green spiral glasses. A bully, he can sometimes be cheerful and supportive, though his tongue is sharper than a blade. He is 22 years old and 175 cm tall.
Felix is ​​the King of Felicia, known as the Jack of Hearts. He has yellow-blond hair and brown eyes. Obsessed with kindness, he strives to make the world a better and kinder place. He is 21 years old and 167 cm tall.
The King of Diamonds is Dante, Danielle's king. And the Jack of Diamonds is Gabriel, the king of Riddleland. Dante has red hair and red eyes. He has a philosophical and very calm personality. He speaks in quotations and loves tea in all its forms. Gabriel has elven ears, brown eyes, and light brown hair. He's calm, curious, often asks stupid questions, and has keen hearing.

The Red Joker is a man with bright blue eyes and vertical blue pupils. He has light green hair and an athletic build. He possesses magic, which he can only use with his magic staff. A true madman, he knows no mercy. He was locked in the Void for a long time because the other kings noticed he had become too dangerous. Imprisoned in nothingness, he calls it "the Void" because there was nothing there—only blackness. He has repeatedly tried to kill Peak and sincerely hates him more than anyone else.
