Yuan and Hotaru81 n
Yuan is blind and wears a blind fold to conceal his Red Eyes trait (his mother, Ian, put it on him because at that time, when he was a kid, have red eyes was frowned upon and you could be killed for this). He has white hair which he inherited from his father. He is a tall and muscolar man. He wears a red sleeveless suit, white pants and red shoes. On his left hand, he has a red tattoo where he primarily uses for his Genshigo.



Yuan personality

Yuan has a rather relaxed attitude and tends to joke around though he is incredibly powerful. He has a habit of sticking out his tongue. Yuan seems to care for Hotaru like a son although he has a harsh way of showing it


He is the second son of Julian and Ian.

He hated the Crimson King.

Yuan Taishirou

Yuan is a prisoner of his family

He became a Taishirou to protect his Family (he can not fight against Fubuki or Hishigi and he didn't want to become a Taishirou member. For this reason he can be considered "a prisoner of his family") but the true purpose is to learn the truth behind his mother's death

He and his father Julian seek to avenge IanInfact Julian has secretely discovered a way to avoid detention and get into the upper level of Red Tower (onmyouden Castle). He is making a shortcut for the day they avenge Ian's death (this because the Red Tower is watched very carefully by the Taishirou). There are traps all over

(however during the fight in volume 31, Fubuki spies on him with using his cat's eyes, so in a sense he was also forced to fight. But he managed to deceive Fubuki watchful eye using Genshigo on his cat). He lost but if he wanted (if he used his full strenght) he could have win easily

Pressure control

Yuan attacked Hotaru by disguising it as an insult. He told Hotaru that he would only use his legs to fight him and if Hotaru was able to force him to use his hand in any way he would spin around three times and bark like a dog. When Hotaru was finally able to do it Yuan hit him with three spinning back fist then superheated the air around him, causing a rise in air pressure in small, enclosed areas which had explosive implications.

6) Taijutsu (Hand to Hand Combat or Martial Arts)

Hand to Hand combat

Wind Blades (2)

The most striking aspect of Yuan's abilities is his prowess in close-quarter-combat. Yuan fights gracefully and relentlessly in a fluid manner, using the motions of the battle to link movements together, smoothly executing combos of kicks and punches

He can also generate shock waves and wind blades with kicks

Yuan typically relies on his hand-to-hand prowess in battle, but when he truly goes all out he combineshis martial arts with his swordsmanship to great effect (when he truly goes all out, he employs a hybrid style, that mixes his mastery of the sword with graceful hand-to-hand combat, making the most use of his exceptional agility and strength)

Yuan's Taijutsu resembles Naruto's Taijutsu (Rock LeeMight Guy) and One Piece's

    Matter is void--All is vanity

    Matter Is Void--All Is Vanity: Yuan attacks his opponent with a flurry of consecutive kicks that inflicts slicing damage, rather than blunt trauma. This kicks has the same effect of a sword, they slices through and severing everything in their way

Genshigo (1)

The power of illusion. Yuan infiltrates his opponents mind and shows them illusions. By making a target believe that he has killed them he is able to destroy their minds and subsequently devour their souls. The draw back is that you need to look at the back of his hand for a period of time and if you have a strong will to live it can be broken.  

8) Fire Style

- Shakuran Entai

A blast of flames is fired at the foe.

- Fire Bunshin

Using high speed, the user quickly creates a fire clone that looks just like them and has the clone take their place. Consequently, the enemy's attack will strike the fire clone and not the person themselves, confounding the foe momentarily, making them vulnerable to a counter attack. Can also be used to successfully retreat from a battle.

- Flame Wall

Yuan summons powerful flames to block enemy attacks. He forms it as a wall in front of him or surrounds his body with flames like an armor.

- Maouen

A larger and more powerful version of Skakuran Entei.

- Kahoenbu

Traps the victim inside a barrier where the oxygen is quickly sucked out, putting out the flames within. However, the spark from the flames still remains. If the victim breaks the barrier, oxygen quickly rushes in to ignite the spark into a fiery explosion, a backdraft. Thus, the victim must choose between suffocation or taking the point blank explosion.

- Demon's Breath

Yuan demon's breath

Demon's Breath

Shoots many small blasts of black flames at the enemy. Black flames are superior to normal flames.

- Hell Crusher

A large sphere of black flames is emitted outward from the user's body. This is an omnidirectional attack.
