Jack Rakan (Jacobus Racan on his pactio card as the "k" in his family name is replaced with a "c" as is standard on all pactio cards), also known as "Rakan of the Thousand Swords," is the large, dark-skinned member of Nagi's group. He appears to be a powerful fighter, demonstrating incredibly destructive attacks with relative ease. His Pactio item is a blade that can transform into (in his words) "any shape imaginable" and can also take the form of a giant sword falling from the sky for an immensely powerful strike. He also demonstrated the ability to emit a high-powered laser from his body at a whim. Rakan initially encounters Negi (in his older disguise) in the Magical World witnessing his battles in the tournaments to raise money to free some of his students. Seeing him without a special ultimate technique, he offers Negi to teach him one for a huge fee. However, after the two of them are attacked by a shadow-manipulator who wants revenge on Nagi, Rakan is forced to save Negi's life for free as well as decides to become his teacher without the fee. Rakan then teaches Negi a technique called Magia Erebea, a forbidden technique created by Evangeline A.K. McDowell. (Source: Wikipedia)
A kind-hearted high school boy with a garden that looks like a jungle, and when the flowers bloom a little too much, he gives them to his classmates and teachers for free. He lives by himself, and supports himself using his inheritance from his late adoptive grandfather. He previously lived with his mother and grandfather, who have both passed away. He is fond of normal household chores (cooking, cleaning, etc.) He has the power of the Sanome to grow plants and he looks like the prince of the alternate world. A bishounen in both worlds. Trusts people easily. (Source: Wikipedia)
The second son in the Ragun family, fifth grade. He'd rather exercise than study, and is the type who reacts before he thinks. He's mischievous and quick to fight, and shows no mercy. He's even childish with the ladies. Jin's a spoiled boy who takes advantage of the fact that his brother is always willing to help. To put it bluntly, he has a weird brother complex. Jin does have an adorable side where he will stretch himself to the breaking point for Yen (and there's also the danger of him going berserk for his brother). In battles with Maga, he's in charge of the attack. (Source: Tokyopop)
