Wazukyan is a Narehate in Ilblu. He is one of The Three Sages, the ones who created Ilblu. He can speak the language of Delvers.

Despite his intimidating and commanding appearance, Wazukyan seems to be pretty laid back. Though he is one of the ones in charge of the village, he is first seen eating at a very crowded restaurant and making pleasantries with the other patrons. Riko bowed very low when she introduced herself to him as a Delver, to which he just replied with "I see! That's great!" and gave her a high five. He seems to have an amiable relationship with most of the other Narehate in the village; he greeted them all very casually as he passed by.

As a human, Wazukyan was essentially the same, if not more serious. Belaf described him as having some sort of a "divine possession" when it came to his instincts. His hunches and predictions were always right, even when he didn't have any prior knowledge, even predicting Vueko's joining Ganja. His crew-mates trusted and respected him as their leader.
