💣📚 | The school’s infamous phony (Sampard/Gepo).

💣🏫 | High school academic rivals (Sampard/Gepo).

A large, broad, muscular monster. There has been rumours of a creature like this on Jarilo-VI as of lately—which may be true, judging by the increase of dead, eaten, maimed animals and people alike—yet there is no absolute proof. Gepard, Captain of the Silvermane Guards, has been Sampo’s ideal mate ever since the beast laid eyes on him… however, Sampo wants to play it safe and slow. He allows him a feeling of peace, until he decides it is time to capture him and steal him away from his siblings.

Aventurine, real name Kavavasha, is a senior manager in the IPC Strategic Investment Department and one of the Ten Stonehearts. He possesses an air of frivolity and doesn't shy away from taking risks. His constant smile makes it difficult for people to discern his true feelings.

His cornerstone is "Aventurine of stratagems”.

🦚🛏️ | Meeting in… a bedroom (Aventio/Ratiorine)?

A classic knight of the Knights of Beauty. Forthright and candid, this noble and admirable man wanders the cosmos alone, resolutely following the Path of Beauty. Upholding the good name of Beauty is Argenti's duty. To fulfil this responsibility, one must be pious when one initiates battle, and one must make their opponent yield willingly when one strikes with one's spear. He is calm, quiet (though, not when he is monologuing/talking about beauty), protective, kind, brave, reasonable, and gentle.

Since William’s fall, Sherlock has become determined to help

🔍🏠 | Tending to a fallen crime noble (Sherliam).

He tends to be somewhat detached from his emotions. With him hardly having a proper social understanding, he's blunt in his teasing and mocking, just like in his ability to give support and be kind.

He’s playful and is hardly ever seen taking something seriously. He is a silver-tongued, witty, money-loving troublemaker who is extremely agile.

A kind, gentle, and cheerful young man with a detail-oriented mind and a pursuit of perfection in everything he does. His fascination with tinkering led him to pursue an engineering degree. He stands at 188 cm tall, and has a lean build. His hair is short and silver-y white with bangs long enough to be styled out of his icy, blue eyes.

☀️📚 | Sleeping in “his” library (Modern!Phaidei).

Sampo Koski is a silver-tongued trickster with catlike, mint-green eyes and a flair for the theatrical. Slippery, charming, and always one step ahead, he masks sharp wit and survival instincts behind a playful smile. A vampire with a soft spot for children and animals, he thrives in deception but fears true vulnerability. Whether cloaked in mystery or swathed in flair, he is equal parts menace and mischief; never where he seems, yet always watching with a sly, knowing glint of cunning amusement.
