Pe Riyuro

Clan King. Born an unrivaled hero among the Quagoa, he quickly rose to the summit of all eight clans and united them. Recognizing the shortcomings of the Quagoa, which had previously been held together solely through violence, he established a somewhat organized political system, successfully eradicating the Quagoa's barbaric practice of denying survival to the defeated. Understanding many of the inherent weaknesses of the Quagoa, such as their lack of exceptional architectural abilities compared to the dwarves, he focuses on subjugating other races to learn their culture and technology to strengthen the Quagoa. His excellence as a king ranks fourth among twelve (being both capable and experienced).

Although nominally submitting to the Frost Dragons, they were granted some degree of autonomy and attempted to invade the dwarves, but withdrew due to the intervention of Ainz and his group. Later, he confronts Shalltear and Aura when they invade his stronghold, "Feo Berkana," with a large army. Understanding that Ainz's group was stronger than the Frost Dragons, he was not averse to joining them. However, his attempt to gather information through negotiations with Shalltear and Aura fails, as the two had no intention of negotiating from the outset, leading to immediate combat. Realizing the overwhelming power of the Sorcerer Kingdom, he reluctantly complies with Shalltear and Aura's demands to cull his clan, entering the Sorcerer Kingdom's rule in fear.

Even under this rule, he seems to be recognized as the ruler of the Quagoa, as he is granted permission to have an audience with Ainz. While waiting in the antechamber for his audience with Ainz, he meets and quickly bonds with Jircniv, who is in a similar situation, and they become close friends.
