Jaryuu

Jaryuu (邪龍, Jaryū), born as Iketsu Tokugawa (徳川池津), is the eldest and firstborn son of Matsudaira Tokugawa making him the older brother of Ieyasu and Chika Tokugawa.

Appearance
Jaryuu is a handsome young man with long black hair, which covers most of his forehead, and all of his back and light brown eyes that seem to have no life in them. His most defining feature is the a large, x-shaped scar across his face. In Volume 26, Jaryuu cut his hair far shorter around the same length as his younger brother.

He is seen wearing a black shitagi, as well as a white Haori, with black sleeves, which give the impression of having gray stripes on each sleeve. Underneath his clothing it is revealed that he has a plethora of scars and marks due to his training around the world.

His face and physique greatly resemble his younger brother, Ieyasu. However, Jaryuu lacks the gentleness that Ieyasu displays and instead comes off as cold with sharpened strength which deviates from the norm according to Sara and Faucheuse.

Personality
Jaryuu is a man of few words with little interest in anything aside from fighting against strong opponents to test the limits of his strength with his little brother stating that he is a stoic person with no interest in anything else expect to become stronger. Because of this, he was interested in fighting against a powerful opponent such as Fuyumi and was disappointed after easily winning against her.

Powers & Abilities
Master Swordsman: Jaryuu is an incredible master swordsman. Ieyasu later noted that there wasn't much difference in sword skills between him and his older brother, which is supplemented by his strength and magic. He could overpower Fuyumi in sword skills alone and landed strikes on her using Winter Maiden of the North. Enhanced Stamina:
 * Sandanzuki (, lit. "Three-Stage Thrust"): A famed technique of Okita Souji, where he launches three strikes at the same time making it a simultaneous strike.
 * Karai : Jaryuu delivers a strong diagonal slash using his right hand, and is followed up with a punch from his left, which supplemented by his strength could send Fuyumi backward breaking through reinforced concrete walls.
 * Sanzensekai (, lit. "Three Thousand Worlds"):

Enhanced Strength:

Enhanced Durability:

Magic: Master Strategist:
 * Hellflame:
 * Spectral Flames:
 * Wind Magic:

Tengu Geppa
Tengu Geppa: Jaryuu's SS- rank Technique, that takes the form of a long Nodachi with a unique snow-white blade, that's over a meter long. Other than being an traditional sword, it has the ability to absorb energy (stamina, ki, magic) from attacks, physical or magical, into the blade, then release the stored up power as powerful slashes and attacks, with the blade turning jet-black when nearing it's limit.
 * Shin Geppa (・): Jaryuu's Awakening.
 * Shin Geppa: Hitomaku Noh (・：): Jaryuu's ultimate technique.
 * Shin Geppa: Tiangou Black Dance (・：): A more powerful version of Geppa: Moon and Dragon.
 * Shin Geppa: Kurokaze Gusoku (・：): A technique, which surrounds Jaryuu with incredibly high pressured magical power leaking from Tengu Geppa. The technique puts a load on Jaryuu's body, training it to become more durable, while also protecting him. By releasing his Armor, Jaryuu gains a massive improvement in speed. He can also put this black wind armor on another person, making them appear invisible by bending light using wind magic.
 * Geppa: Moon and the Dragon: Jaryuu's second most powerful technique similar to "Kheimon Drakainathea", where Jaryuu pours his magic inside Tengu Geppa then releases both it and Geppa's stored power, creating a powerful, serpent-like black windstorm that is able to suck in everything around him including the atmosphere surpassing 50 meters in height. At full strength, it could overpower Fuyumi's and Ren's strongest moves, turning the school building, the practice area, and paving into rubble. Geppa: MD, however, has a flaw as its power drops with each usage, in evidence when Jaryuu noted a decrease in power by the third usage during his short fight against Miyatsuko and Momozono.
 * Ougi Geppa: Shin'uchi (・：): This is the true form of Geppa: Moon and the Dragon and Shin Geppa: Tiangou Black Dance, which he couldn't realize using his own power, where he continues to compress the enormous magical black tornado using the magic he took from the surrounding area into the form of a jet black blade with a light edge slightly larger than his Tengu Geppa. Shin'uchi terrified even Elias Carter who stated that the thin blade has the power to twist the space of the world and cut the natural magic flow of the surrounding area.
 * Ougi Geppa: Ikki no Kaze (・：): One of his most powerful techniques, which can be used after Ougi Geppa: Shin'uchi is activated, where he slashes everything within 500 km of the trajectory where Tengu Geppa is swung in a straight line. It was powerful enough to kill Elias Carter.
 * Mukuu Kekkai: Jaryuu creates a powerful updraft with wind magic to deprive his opponent of oxygen and absorb their magic power. It also serves to momentarily distract the opponent and has a considerable range.
 * San: A more lethal version of the original, where he creates a vacuum, which can boil and vaporize his opponents' fluids, their bodies' decaying a lot like trees.
 * Geppa: Chigurozan
 * Geppa: Kuro Jinsenpuu
 * Getsugan: A technique where Jaryuu reads and listens to the wind, following the traces of magic power scattered in the wind in order to locate his targets.
 * Mugetsu Yozora no Sesshoku
