Akki Kubasta

This is the ybrid of the "bullfight" (in this pic here:  The Duke and Akki).

The one in the corner top right is his father, who happens to be the also the father of the Duke.  So the bull and the matador are half brothers, to make things more complicated.

Akki is a sub-human that became a ybrid. Also, he is one of the few Ybrids that actively fight against the nazys, and he is the number two most wanted Ybrid of the Empire. In fact, the only Ybrids that cause troubles to the Nazys are those that once were humans: real Ybrids never rebel or claim their rights.

Plus, he is especially hated by Stilfser, because he suspects that he had an affair with his wife Sara  (when he was still a human hopefully!!! )
