Rhash kind of already expected that if he and Reif were to defeat Agui, he would have another slave
If Khaknur was wimpy from the inside and out, Agui on the other hand was wimpy only on the inside
If he thinks he could defeat the enemies that came to him, he would act arrogantly in front of them
However, once he is defeated, to save his life, he would surrender everything that he has
Agui has appeared in Rhash's dreams but sadly, it was Nath that became his master in the original timeline
A similar thing had happened back then. Nath was chasing the injured Reif and they both arrived in this area
If not for Agui's appearance, Reif might not be able to flee at that time due to his severe injuries
It was Agui that gave Reif a chance to flee as he attacks everyone indiscriminately. Well, his ending wasn't that good though as he was demoted into a slave after he was defeated by Nath and the forces he brought with him
