She is extremely arrogant, a self-styled polymath who constantly belittles those around her. While her knowledge about technology, species, history, and the galaxy in general is vast, it is mostly academic. She is extremely naive and unknowledgeable about how things function outside a controlled environment (such as learning Leviathan physiology strictly via studying and not understanding that the floorplans of the biomechanoids vary as a result of passenger preference). Sikozu's sense of self-preservation is foremost in her mind, and so she is prone to switching sides in any conflict with no notice and seemingly no premeditation other than ad hoc judgments on who currently holds the greatest advantage. This makes her true loyalties (if any) uncertain.
