Kai was a tall, stately man with graceful features. He looked like an aristocrat. White skin, black hair, and a hooked nose.

Homophobia was rampant in his time, and he was married to a woman he loved, but he provided for and supported her as a companion.

However, he had a lover, Oliver. Oliver was a former, impoverished opposition figure, but Kai raised him from his knees and gave him a house. Kai's love language for Oliver is pain and threats. He openly praises, comforts, and caresses him, but also inflicts pain, both emotional and physical.
