Zaryusu Shasha

A traveler from the "Green Claw" tribe. He brought back knowledge of fish farming from the outside world and, with the covert help of his brother, made it successful. As a warrior, he is known as one of the strongest in the surrounding tribes and is recognized as the owner of one of the Four Great Treasures of the Lizardmen, "Frost Pain."

To counter the invasion of Nazarick, he proposed an alliance with the surrounding tribes and, sharing responsibilities with his brother, successfully negotiated it. During the battle with Nazarick, despite the overwhelming difference in abilities, he managed to defeat Igva with the cooperation of his comrades, and his coordination with his brother allowed him to land a blade on Cocytus, earning Cocytus' respect as a warrior.

Though he died in the battle with Cocytus, he was resurrected as an experiment for revival magic. Witnessing the ease with which he was revived and the commanding presence of Ainz over the forces of Nazarick, he came to recognize Ainz as a god-like being and bowed before him.

After the invasion of Nazarick, he went with Zaryusu and others to the Great Tomb of Nazarick to teach warrior skills to Hamsuke and other lizardmen.
