Sitri

Sitri is a great demon counted among the Thirteen Calamities of the Ruined Nation, wielding the power to manipulate illusions and dimensional space. His form is that of a half-dragon, half-human being with wings. Deeply arrogant by nature and dismissive of humankind, he is known to fall into slumbers that span hundreds of years at a time. Over the course of the story, he forges a contract with the demonized Sno, and despite occupying an antagonistic position, he demonstrates a profound sense of responsibility and loyalty toward his companions.
