Dandalg is a prominent character in the anime I Parry Everything, recognized as one of the Six Saints, the most powerful protectors of the Kingdom of Clays. He holds the title of Shield Saint, a name bestowed upon him by the king himself, who declared that Dandalg himself is the kingdom's shield. This title is somewhat ironic, as Dandalg does not actually use a physical shield in combat; his entire being serves as a bulwark against threats. Physically, he is an adult man with striking features, including blue eyes and red hair that falls to his shoulders, and he is often seen wearing armor.

As a member of the Sovereign Six, Dandalg plays a crucial defensive role in the kingdom's survival. Beyond his duties as a living shield, he also serves as an instructor at the royal capital's warrior training facility. His background is deeply tied to his role as a mentor and father figure. He took Ines, a young girl with the Holy Shield ability, under his wing from an orphanage, raising her as his own daughter. He trained her rigorously, and she eventually became a maid and protector to the noblewoman Lynneburg, or Lynne. In this way, Dandalg's legacy of defense is passed down through his teachings.

Dandalg's personality is defined by his ability to perceive and nurture raw potential in others. Years before the main events of the story, he trained the protagonist, Noor, in the arts of defense. During this time, he saw vast latent power within Noor, a hidden potential so captivating that Dandalg even considered training him to become a literal invincible shield. Unlike those who dismissed Noor's lack of conventional skill, Dandalg recognized a different kind of strength. However, he also carried a practical concern for Noor's safety, worrying that placing him directly on the front lines might cost the young man his life. This combination of insight and care defines his approach to teaching and leadership.

His motivations are rooted in protection, both of the kingdom he serves and the individuals he trains. As the Shield Saint, his existence is dedicated to defending Clays from external threats like the Deridas Empire. As an instructor, he is driven to see his students grow, though he is not blind to their limitations. His relationship with Ines is particularly strong, functioning as both a master to his student and a father to his daughter. He also shares a connection with his fellow sovereign, Sig, as they both taught Noor and later shared regret over losing contact with him after his training concluded. In fact, Dandalg once asked Sig if he was alright with not having spoken to Noor, highlighting their shared sense of responsibility for the wandering hero.

In terms of abilities, Dandalg is one of the strongest warriors in the kingdom, earning his place among the Six Saints. His defensive prowess is so absolute that he himself is considered a shield, requiring no physical armament to block attacks. His training methods are evidently effective, as his adopted daughter Ines became a capable fighter in her own right. He also demonstrated remarkable foresight in recognizing Noor's true potential, suggesting a keen analytical ability that goes beyond surface-level observations. While he does not possess flashy offensive powers, his role as the ultimate defender makes him an indispensable bulwark for his nation. His development in the story revolves around his past as a mentor, his present as a guardian of the realm, and his lasting influence on the younger generation of warriors he shaped.
