Marcus' past actions have earned him the moniker of 'betrayer' or 'traitor'. Having since changed his ways, he is now fiercely loyal to the Clan and spends much of his time proving this to his betters and his peers. Some people, however, may not believe him outright.

The scars that crawl all over Marcus Kiriyu’s body serve as a permanent reminder of the events on Dentavii, where he fell too far. Since then he has vowed never to fall to the trappings of power beyond his reach. If he is to become stronger, it must be by his own hand.

Marcus keeps his composure in almost every situation, believing that the rules of etiquette exist for a reason. He will always address his superiors by their rank, and will become offended if he isn't offered the same courtesy by both superior and peer. This can of course result in people thinking Marcus has a stick up his ass.

People tend to reverently follow Marcus Kiriyu’s lead and look up to him in difficult situations. Whether through inspirational behavior, fear and manipulation, or belief and hope for a better future, they think that Marcus Kiriyu genuinely believes what he does. This is all a clever facade, however, as Marcus Kiriyu is not always as upstanding and respectable as his followers believe. He is no idol, but an opportunist who knows how to manipulate a crowd into bettering his own machinations.

Through careful study and dedication to isolated martial-combat, Marcus Kiriyu has turned the act of dueling into an art form. A keen eye and attention to detail allows him the ability to learn their opponent's idiosyncrasies while fighting. Marcus Kiriyu then uses his own skills to capitalize on the opponent's weakness. Because of this calculated approach to isolated duels, Marcus Kiriyu has a harder time taking on multiple opponents at once at higher skill levels.

Marcus Kiriyu has mastered his own form of melee combat, Hin'Tan, which combines elements from Broken Gate with Barrier and Telekinesis. It works by protecting his extremities with a Force-powered barrier, protecting them from harm. This technique requires significant concentration on the part of the user, linked directly to their skill in the Force power Barrier.

The art of Hin'Tan focuses on blocking, or swatting aside, physical attacks, allowing a practitioner to get to close to their opponent and pummel them with punches charged with telekinetic energy, dealing devastating damage. Hin'Tan is highly dependent on the user's own agility and ruthlessness in combat, as well as having no support for any weapons. It's use is therefor dangerous as the practitioner is effectively exposed unless he can keep the focus required to raise the barriers and concentrate his telekinesis.
