#. 🐈‍⬛ - Yves Kloss.

He seems somewhat hostile, confident, prideful, and haughty on the first glance. He prefers to be referred to as "Your Highness", but his bratty demeanor quickly melts into a kind man who takes care of those around him. He secretly has a soft and affectionate side, and because of this, he's usually the target of his half-brothers’ teasing. He is a rather genuine, trusting, and gullible man who falls for the same tricks again and again.

However, under his prideful and hostile facade, he's an extremely insecure and self-hating individual. Born as half-Obsidianite, the people around him treat him more like a tumor than a person, assuming that he will one day betray the kingdom. Most parents keep their children away from him, he is always constantly gossiped about, and he's made to feel unwelcome during social gatherings. Even the people in his territory, who he tries his best to look after, despise him so much that they don't want to him to lead them. A sensitive person, this behavior from others makes him feel guilty just for existing, and he tends not to join others for fear that he'll ruin the fun for them. This has unfortunately led to him believing that he doesn't deserve kindness, claiming that although people hate him no one can despise him as much as he does.

Regarding his family tree, it's quite complicated to explain, all of his brothers didn't come from the same mother. Their late father only took care of their mothers out of obligation, since the woman he loved was always the former Belle. From then on, all of his half-brothers, including him, are a group of competing men; they are required to fight and battle to be chosen as the next future king by the current Belle.

These are their orders:
Jin Grandet, the eldest and first prince
Chevalier Michael, the second prince
Clavis Lelouch, the third prince
Leon Dompteur, the fourth prince
Yves Kloss, the fifth prince
Licht Klein, the sixth prince and oldest twin
Nokto Klein, the seventh prince and Licht's younger twin
Luke Randolph, the eight prince

Yves appears to be a short man with a slender build, he has mesmerizing, radiant blue eyes and soft honey-blonde hair that's parted on the left side, which covers his face slightly.

He has multiple piercings and wears a conspicuous, jeweled earring that dangles from his left ear, creating an elegant look.

He wears a fancy pink attire, adorned with beautiful accessories and an astonishing embroidery pattern, matching his delicate appearance. He's a man of excellent taste.

He's been described as a stunningly beautiful man, looking more like "a portrait of idealized beauty" than a human being.
