Alright, I have garnered enough interest to try this out.

Humans:
Name: Jordan Montoya 
Age: 16
Appearance: [url=http://safebooru.org//images/1003/3fc3e19d395550a126e81fe47caea08c9b826e71.png?1008726]"So, whatcha wanna buy?"[/url]
Personality: Jordan was raised with only one thing in mind: those with the most money win. He's taken that lifetime family motto to heart and will do almost anything to make a quick buck. [i]Almost[/i] anything. He's no Judas, he's not gonna sell someone out for thirty pieces of silver, and he's too afraid to actually kill for money. What he can do, however, is talk a good deal about what he's currently selling at that time. We're talking Honest John styles of talking here. Fast-talking, shilling, he'll even break into a musical number to get you to buy his product. And the funny thing is that the product [i]won't[/i] be glorified snake oil. If he says he has a product that can do something cool and wonderful, he means it. With his contract, Jordan became opportunistic, looking at both sides and trying to strike a deal for all of them. As such, he's more in the middle.
Clubs: Entrepreneurs Club
Brief Backstory: His family came from a strong line of Spanish Conquistadors who had reported sightings of a strange creature with a gem on its head in South America. However, attempts to capture it proved infallible, as the creature would blind them if they ever gotten close to it and most importantly, the gem on its head. However, one of them, who would later become Jordan's ancestor, figured out exactly how to calm the creature and convince it that he won't hurt it. The creature smiled and bonded with the ancestor, giving him the gemstone as in trade for convincing the other Conquistadors to leave. Upon doing so, Jordan's ancestor received tremendous luck, as the Conquistadors ran off and left their valuables behind. This is the cause for Jordan's wealthy upbringing many years later. When Jordan was old enough, he was taken to a strange room by his father and was revealed the story of the encounter with the Carbuncle. He is given the gemstone, preserved for the generations, as a calling card to summon a Carbuncle to contract with, as per family tradition. He contracted with one and was told to treasure and respect the Carbuncle like its his last hope. With that, he went on his way to Covenant Academy.
Contract(s): Carbuncle 

Contracted Beings:
Name: It has no name, but Jordan calls him Carbie.
Type: Carbuncle
Personality: Carbie was summoned and contracted as a baby, so his personality and mind is pretty child-like, only cooing and crying to communicate with anyone else. Its too young and innocent to detect any ulterior motives yet, a key ability for the Carbuncles to have when dealing with humans with greed in their hearts, which is probably why he and Jordan have their contract... For now at least.
Powers: Carbie can blind people for a few seconds. He is able to sense the desires in people's hearts, though only to judge whether they want the gemstone on his head for wealth or not. As he is still in an infantile stage, however, he won't be able to put two and two together and will just give the gemstone regardless.
Fusion: Jordan's top-hat turns into a large jewel crown on his head, while his jacket turns into a long, pink gemstone cape, broken to small tiny pieces so as to flutter about in the wind and not be a hassle for him. The gemstone on the Carbuncle's forehead now becomes the gemstone on Jordan's chest, and it acts as the main source for his powers. However, because the forehead gem isn't clear as crystal in what it can do, his power is being able to blind people, the same power that Carbie has, though lasting for at least half a minute.
Summon: [url=http://img3.wikia.nocookie.net/__cb20130315165226/finalfantasy/images/f/fc/Carbuncle_FFVIII_Art.png]"Coooo..."[/url] Carbie can produce gemstones from its forehead, which fall out in time only to be replaced by another gemstone. Each gemstone has a magical affinity, always elemental. One gemstone could spew out fire, while another could simply shock you with lightning. Because of his age, these gemstones are more likely than not weak compared to say, an elemental-based Contract would have, but there's the added benefit that anyone with magic can use these gemstones.
