Zuke Ukashi,  later known as "Red Valor Zuke" and commonly as "Crimson King", is the main protagonist of the series, XenTerra: Mystic Arts. He is the founder and of the later infamous and powerful Team Z, as well as one of its top fighters. Due to most people in his childhood despising magic, Zuke desires to become a XenTerra's Top mage and to show the world that magic isn't meant to be feared nor hated.

Alias: Zu, ZuZu, Red Demon, Captain Zuke, Crimson King, Stud Muffin

Origin: Swinford Town (Formerly), XenTerra

Gender: Male

Age: 15

Birthday: January 16

Classification: Mage

Height: 171 cm (5'6")

Weight: 63½ kg (140 lb.)

Appearance: Zuke is a lean, yet muscular young man of average height with spiky magneta hair which partially covers his ears, light violet eyes, red eyebrows and tanned-skin. His main outfit consists of a black long-sleeved jacket, with the sleeves rolled up to his forearms, a pocket on the left side of the chest with golden-colored trimming. Underneath, he wears a simple red shirt. He also wears black baggy pants held by a leather brown belt with a silver buckle around his waist, and a pair of dark brown, high-calf boots; there are several yellow patterns on the jacket and pants. Lastly, he wears a pair of gloves; red on the bottom, black on the top.

Personality: Zuke is a carefree and eager individual. He also a fiercely loyal and protective friend, willing to go down fighting for his friends, regardless of how futile it might seem. 

Zuke continuously tries to prove his strength to others. At various points in time, he has challenged Reina, Arthias, Damian, Aisha and Jalenn to fight him. Despite his losses, Zuke bears them no ill will, as he considers them, and Alice, his close allies. Due to his fierce nature, Zuke's fights usually ends with widespread destruction. His love of fighting has allowed him to develop a rather strategic mind, helping him to, on various occasions, find weaknesses in his opponent's techniques, or simply weaknesses his opponents themselves possess. Zuke learns to defeat his opponents with pure wit, rather than brute strength. He never backs out of a fight.

Zuke rarely exhibits any perverse tendencies towards the opposite sex, though he has noted Alice and Reina are very sexy, among the other girls in XenTerra. Though one time is when he see Alice naked, he stares at her body, even groping her breasts for a moment.

Zuke dislikes weak people, though not strictly in a physical sense, but those who show cowardly nature. Conversely, he likes people who put in the effort to make something of themselves, despite their limitations. An example is when Alice tells him about her goals to become a mage and travel the world rather than being seen as just a 'royal'. He is actively annoyed at people who tell him things are "impossible" and will even hit people (men or women) who push the issue too far.

Zuke has shown to admire heroic figures, though he has stated vehemently that he doesn't want to be one, with his primary hang up being that heroes are fundamentally entirely selfless, and Zuke not really identifying that trait. Ironically, many of Zuke's actions are immensely selfless, with his selfishness mainly revolving around his thirst for adventure and battle. This trait leaves everyone he meets with to think he is some kind of hero, but not by his own design. Eventually, he warms up to the idea of being a hero as Arthias explains the true meaning of being a mage.

Genkai Arts: Evening Dragon - Zuke unleashes a furious barrage of punches, lifting the opponent higher into the air until he flash-steps behind them and smashes them back down to the ground with an energized punch. Charging two orbs of aura in his hands, which take on the form of dragon heads, Zuke flies back down at the opponent and rams them face-first with the attack, obliterating them.

Genkai Arts: Night Rakshasa - Zuke charges aura magic in his palms to create a vermillion sphere, then fires it at the enemy.
