Leia

"The heart and soul are closely linked. Your heart reveals what is most precious to you."

Leia (Or Leia Zaizen Aphelion, or just Leia Zaizen), is the leader and founder of the DC. She is also a member of the infamous Aphelion Clan, and wields it's prized heirloom: The venomous katana, Kodachi.

Personality
Out of all the members of the DC, Leia is the most serene and has rarely been seen to act comically. She is the quieter, more reserved DC member, rarely having outbursts of emotions (occasional exceptions being sweat drops, and the like). She even appears calm while speaking ominously around her experiments. She has an "adult charm" about her, as stated by Rayna. Being described as the "mother" by her creator, she in kind has shown maternal care for others.

Her silence seems to stem from her sense of decorum and personal pride on many occasions, she flatly refuses to engage in any behavior that would be considered embarrassing.

As the leader of the DC, Leia is committed to protecting New York and its inhabitants, willing to give her life for the civilians and experiments if necessary. Just as she once did, Leia supports all other dreams that she can. She in fact becomes angry when others lack this same faith in her experiments and peers, believing it is better to let them try and then fail than to assume their failure is inevitable and thus prevent them from trying.

Despite her many noble qualities, Leia is not without her faults. She is blunt and short-tempered, prone to striking Ezauer for his immaturity or Mason for his perversion; she is widely feared because of this tendency.

One of Leia's defining traits is her utter lack of fear regarding a situation. She has only shown fear in very few cases and always involving an extremely dangerous threat directly falling on her.

In contrast to her distant and reserved demeanor, Leia is actually caring and compassionate.

She will never understand why people regard history as meaningless. To her, there is nothing worse than destroying objects of historical significance. She approaches life and the world at large in a calm manner. She studies the world for its history. She shows little interest in the ancient weapons that others seek, claiming she needs nothing but her trusty katana.

During battle, Leia tends to maintain a relaxed demeanor that only seems to change whenever the circumstances proved to be beyond her capacity to cope (i.e. a hopeless situation). More often than not, she would exhibit unshakable calmness and reserved behavior against an inferior adversary.

As a result of her violent past, she is very merciless in combat and does not shy away from using deadly force. She will break the necks or spines of her enemies without hesitation, even when they cry for forgiveness. Despite her tendency to remain calm and collected, she can be quite intimidating and forceful when she wishes.

Powers and Abilities
Martial Arts: A trained samurai, she is well versed in various styles relating to swords.

Master Swordsmanship Specialist: Leia's swordsmanship is rough, but far from unrefined. She's an extraordinary swordswoman renown enough to earn the epithet "God of the Sword". Her level of skill has been complemented by several esteemed swordmasters, one of whom noted that her style is something not taught but developed by Leia herself.

Weapon Expertise: While Leia vastly prefers to make use of her swordsmanship in combat, she is well-versed in the use of many types of weapons, from naginatas and kunai to senbon and explosives, likely due to her training as a samurai and time spent on the battlefield. She is able to incorporate the use of almost anything she finds in a fight and frequently catches her opponents off-guard by using her surroundings against them.

Super Strength: Her physical accomplishments, whatever the cause, include: splitting the ground with only a finger and breaking six of Mason's ribs, both his arms, and rupturing several of his internal organs. She can use targeted thrusts at joints and vital spots in order to incapacitate physical functions and return counterattacks after anticipated her opponent's movements.

Immense Speed and Reflexes: Leia possesses an extreme amount of speed and reflexes, far surpassing that of average humans.

Tremendous Endurance: One of Leia's defining traits is her extreme level of physical endurance. Leia fights without consideration for her life, most of the time, and while this gives her the ability to fight without limits, it is also a testament to how little Leia values her own life. Coupled with her incredibly high pain tolerance, this makes her an incredibly fearsome fighter.

Enhanced Senses: Leia is able to sense the trajectory of bullets, even in the dark. She can predict the movements of enemy attacks. She is also able to sense that people are watching her, as she realizes she is being watched by two monsters despite being engaged in combat at the time, as well as being able to sense killing intent very clearly. It is also shown that her sense is sharp enough to enable her to deflect a barrage of shots from a Gatling gun flawlessly without letting a single shot hit her.

Soul Resonance: Leia is able to synchronize her soul with her katana, Kodachi, combining them temporarily. This seems to be caused by their strong bond with each other. During the resonance, Kodachi's poison enters Leia, causing purple markings to appear on her face. These markings have been compared to the markings of a demon. Leia then turns into a berserk-like state, becoming stronger, faster, more durable, etc., but her mind isn't completely... there. Her voice becomes somewhat distorted, as if her and Kodachi were speaking at the same time. After the time is up, she'll go back to normal and needs to rest afterwards as it tires both her and Kodachi out.

Poison Immunity: Leia, and everyone in her clan, is immune to the poison that Kodachi produces, which makes them able to wield the blade without any repercussions.

Techniques
Akuma-no-ago: This is an omnidirectional attack that emits a large sphere of black flames outward from Leia.

Delightful Inferno: Leia coats her sword with a green aura before jumping right in with a fury of hard-hitting slashes. This move ends with Leia sheathing her sword and a ravenous explosion of power sends enemies flying.

Hassō-no-kamae: It is an offensive stance, named for one's ability to respond to a situation in any direction. In hassō-no-kamae, the left foot is forward, and the sword is held pointing upright with the hilt in front of the right shoulder. The blade should slope slightly to the rear. When cutting, the sword is raised above the head.

Hayabusa: Leia takes a stance before she begins to swing her katana about, creating a barrage of slashes. She moves forward in a slowed pace, however, each swing is backed by power and the fiery essence of her energy. To finish this move, she ends it with a switch swift uppercut, followed by one final slash of her katana.

Hokuto Seven Stars: Leia rushes the opponent and deals a series of vicious sword strike combinations.

Kaze No Oe: Leia sends a massive air shockwave along the ground to attack the opponent while at the same instant using her speed. She appears one moment right behind the attack so that if the attack does not kill the opponent, she can finish the job in a instant.

Zekka Hoōsen Yomishik: Leia unsheathes Kodachi, tosses the sheath up in the air, and places both hands on its handle. From there, the sword is immersed in a fiery green aura as it extends and elongates in size. She then takes the sword and strikes down one time, creating a long beam that splits through the middle and travels outward towards the enemies.

Shakuran Entei: At the instant of the slash, Leia releases highly condensed flame at the tip of her blade, magnifying the slash attack before flying forward. This slash takes the form of a vacuum of blazing flame, which can burn through anything it touches. This is a powerful technique with great force, capable of causing large-scale damage and destruction.

Hōzuri: A simple but precise slash technique which is meant only to lightly graze and cause superficial wounds.

Shitonegaeshi: A pinning technique which subdues an opponent and immobilizes them on the ground using coercion alone, with Leia suspending the tip of her sword just millimeters from their face after she has struck them down.

Tsukiyubi: A technique where the user simply extends the index and middle fingers of one hand in unison while they are in contact with an opponent. This gesture possesses enough physical force to effortlessly send someone of even Rae's stature flying several meters away.

Agitowari: A single sword attack which cuts an opponent in half from the jaw down the length of the body until the target is bisected.

Ichirō Zaizen
Leia's relationship with her older brother, Ichirō, is a shaky one. When Leia inherited the family heirloom, Kodachi, Ichirō resented Leia because Kodachi was supposed to go to him. However, since Ichirō lacked the skills to be a samurai, it went to Leia instead.
