Ruijerd Superdia

A warrior of the demon race known as the "Supard" with the alias "Dead End." Known as the watchdog of Dead End.

He is taciturn and stubborn, holding the pride that "a warrior should protect children and cherish his comrades," and treats those who oppose this belief as vile and evil. He is merciless towards those who harm children, but at the same time, he is kind and caring towards them.

With over 500 years of combat experience, his combat ability is on par with an imperial swordsman. He can see the magical energy around him through the gem on his forehead, making him adept at fighting in chaotic battles or places with many obstacles. He also uses a demon race combat technique that manipulates the opponent's movements with his gaze.

He was once the captain of the demon god Laplace's personal guard, but during the middle of the Laplace campaign, he was forced by the Supard warriors to use a cursed spear created by the demon god Laplace. As a result, both he and his warriors' minds were corrupted by the cursed spear, losing the ability to distinguish between friend and foe, leading him to kill his own son. When his son broke the cursed spear, he regained his sanity and vowed revenge against the demon god Laplace. After years of hiding, he interfered in the battle between the three heroes who killed demon gods and demon god Laplace, striking back.

Afterward, while searching for his kin, he tried to restore the tarnished honor of the Supard race by helping children and killing villains he encountered. However, his actions only incited more fear among those around him, and he began to be treated like a monster, known as "Dead End" (meeting him means death).

During the Fittoa domain transfer incident, he helped Rudeus and Eris, who had been transferred to the demon continent, and promised to escort them to the Fittoa domain. In return, Rudeus agreed to help restore the honor of the Supard race. Initially, there were conflicts due to differences in values with Rudeus, but when threatened by Nokopara, Rudeus's determination to protect Eris at all costs earned his recognition. He then revealed his true identity as a Supard and took the blame alone to protect Rudeus and the others, building a mutual trust.

Three years later, upon reaching the Fittoa domain, he expressed his gratitude to Rudeus and parted ways, continuing his search for fellow Supard in the Central Continent.
