Yuru rarely acts on impulse. Even when faced with life-threatening danger or shocking twists regarding his family, he keeps his emotions in check, adapting quickly to bizarre or unfamiliar modern situations. He is deeply devoted to his loved ones. Before the siege on his village, he was known to ask for nothing for himself, instead focusing entirely on the well-being of his sister (Asa) and making promises to protect her. Trained as a hunter and archer, he has sharp reflexes and a ferocious, "wild" determination in a fight. He holds a strong offensive mindset and won't hesitate to fight with lethal intent against those trying to kill him or his loved ones. Despite his sheltered upbringing, he does not shy away from the confusing aspects of the modern world.

Having lived outside the secluded village since childhood, she was forced to mature quickly in a dangerous world. As a result, she takes on a strong, masculine, and often intimidating approach to combat and survival. Her entire world revolves around Yuru. Despite being the younger twin, she acts like an overprotective older sister, going to extreme lengths to ensure his safety. When emotions run high around him, her cool façade completely crumbles into tears and exaggerated affection. She harbors a deep hatred for the village that caged a fake double of her, and will seek revenge against those who have harmed her family. Despite this, she retains a moral compass, going out of her way to avoid harming children. Destined to rule the Tsugai, her character development and intense devotion remain a core focus of the series.

Unlike Right—who is loud, boastful, and eager to act—Hidari is quiet, serious, and deeply focused. She rarely wastes words and prefers to let her actions speak for her. Because Yuru views his Tsugai as gods rather than tools, he gives them freedom to act. Hidari takes this responsibility seriously, acting with a level-headedness that keeps both Yuru and Right out of unnecessary trouble. Representing the Moon, she serves as the seal. In critical situations, she displays a fierce, uncompromising determination for violence if her allies are threatened.

Migi is highly aggressive, thrill-seeking, and faces combat with a massive grin. He is boisterous, loud, and much more outwardly curious and expressive than his counterpart. He boasts incredible physical strength and can transform into a hardened stone state to overwhelm opponents. Though he can come off as rough, he is fiercely devoted and fiercely protective of his master.
