Shin Reglia

Shin Reglia (シン・レグリア) is the right-hand man of the Demon King Anos Voldigoad and the most powerful swordsman among the demons.

He is the husband of the Great Spirit Reno, and the father of their daughter, Misa. He became the Spirit King after Reno's passing and founded the Unitarians to create a better place for Misa due to her mixed-blood status.

Appearance
Shin has gray hair, colorless eyes, and a large vertical scar over his left eye. He dresses in black armor and a black coat, usually carrying a sword.

Personality
Shin is a composed, calm and strong man. According to Anos, he is a man of great strength but low ambition, as he faithfully served Anos during the Great War. Due to his stoic nature, he often seems emotionless, as he has great difficulty adjusting to things that do not involve swords or battle. Yet, he has proven himself to be a swordsman of great pride as after facing his first ever defeat by Hero Kanon, he pushed himself into becoming even more powerful so he wouldn't face defeat again.

History
Originally, Shin was a demon sword created by ancient demons to fight against the gods, as it gradually gained its own will during the battles against the gods. However, Shin's last wielder noticed the limits of his power, as he could not destroy the gods. So he endowed Shin with all of his strength, as he had hoped that in the future, someone else could wield Shin to defeat the gods, as the demon disappeared. After that, Shin somehow gained the physical form of a demon and became a living being, though he couldn't understand feelings or emotions as his source was still that of a demonic sword.

During the Great War, Shin met and challenged various famous demons to test their strength but easily defeated them with his own superior strength and swordsmanship skills. Eventually, he met the leader of the demons, Demon King Anos Voldigoad. Shin challenged him to a fight, but Anos could repel all his attacks, even though Shin had used over a hundred different demon swords. Growing interested in Anos, Shin asked him why he was so strong. Anos replied that "the weak cannot help anyone" as Anos countered and asked Shin why he was so strong, as Shin couldn't come up with a proper response, simply stating that he was strong because he was strong, as he was an ordinary sword. Anos asked Shin to become his subordinate. Shin accepted as he had finally found a master worthy of his loyalty, eventually rising to become Anos' right-hand and most trusted subordinate.

As the Great War continued, Shin would encounter his master's rival, the Hero Kanon, and the two would have swordsmanship fights ending in a draw. However, Kanon would eventually win against Shin once, as that defeat would spurn Shin into training himself to become even stronger.

Shin accompanied Anos and his army to invade Aharthern, as all of Anos' forces were wiped out by the Great Water Spirit, Lignon. As Anos moved to deal with her, Shin knelt and asked Anos for permission to deal with her, with Anos accepted on a wager condition. If Shin dispatched her in a single blow, Anos would grant him any reward he wanted, and if Anos won, Shin would be forced to drop his formal tone of speech with Anos as Shin accepted the wager and moved to attack her. Shin managed to use his sword to slice her into pieces in a single blow. When asked what he wanted as a reward, Shin asked Anos permission to be reincarnated so he could once again serve Anos, which Anos readily agreed to. As Anos noticed Hero Kanon approaching, he ordered Shin to find the Great Spirit Reno while Anos himself faced Kanon as Shin teleported to carry out his orders.

Two thousand years ago, Anos ordered Shin to stay at Aharthern and protect the Great Spirit Mother Reno; since Nosgalia intended to turn her into the vessel who would give birth to the "Child of God".

After he married Reno and a child was on the way, he returned to Delsgade to reincarnate. However, as he was preparing to do so, Titi spirits came from Aharthern to tell him that Reno was in danger. Shin immediately rushed back, only to find Nosgalia with a dying Reno, causing him to attack and severely injure Nosgalia. Shin then embraced Reno's body as she was about to disappear.

Reno thanked Shin for protecting her and asked him to end their daughter's life if she ever threatened the world, as she was born from the story of the Fictional Demon King of Tyranny Avos Dilhevia. Despite being the right hand of the true Demon King of Tyranny, Shin refused, saying that he would create a world for their child to live in. After Reno's death, Shin continued to live without reincarnating, spreading rumors about Avos for his daughter to continue living. Due to Reno's disappearance, he also took over her role as protector and leader of the spirits in Aharthern, becoming known as the Spirit King and for 2,000 years he continued honing his swordsmanship till he became unrivalled.

Abilities

 * Immense Magic Power: Shin had an incredible amount of magic power, but according to Anos, he wasn't very good with spells. Anos remarked that he was one of the most powerful beings that were active during the Mythical Age.
 * Immense Speed: Shin possesses immense speed, as he was able to defeat Lignon and return to his kneeling position in a blink of an eye, almost as if he never moved. He was also able to keep up with Lay's speed and even outpace him at times during their duel.
 * Master Swordsman: Shin is the most powerful swordsman of the demon race, as he had mastered every demon sword in existence and has a thousand sword techniques. He is considered Anos' most powerful subordinate from the Mythical Age, as he could even battle gods and win. He demonstrated his swordsmanship prowess by defeating the Great Water Spirit in a single blow with a regular iron sword. According to Lay, he could even fight against the Four Evil Kings simultaneously and still be the victor. Lay also noted that Shin was far more skilled in the present than two thousand years ago. He demonstrated the ability to easily deprive the functionality of Eldmed' limbs in the blink of an eye by rapidly slashing him with his Pillage Blade. He later easily defeated numerous divine beasts and overwhelmed the Nosgalia-possessed Eldmed, although it was noted that Nosgalia was still injured as a result of his prior defeat by Anos.

Trivia

 * Shin is bad at source magic, as Anos stated that if he reincarnated, then he would lose his memories and skills, which Shin confirmed as he stated that he might start over with a new sword if he is reincarnated.
 * Shin was stated to have a terrible affinity for magic items besides demon swords, although he learned to solve anything with swords alone.
