Kaysān Haakii

"I can tell you are a good person. Not to worry, you won't fear what others think of your actions once you lose your inhibition."

Kaysān Haakii is is the head of the Sēvaka clan and Kenran's adoptive brother. He also married his adopted sister, Reika Sonkeii.

Personality
Kaysān openly refers to himself as a "deviant trickster", using his craftiness and intelligence to devise highly unorthodox strategies for the benefit of Heiyān. Kaysān is a double-edged sword: he always remembers to repay his debts (whether morally just or unjust) yet never forgets those who have wronged him, making him an outsider with a sinister edge to other characters. Despite his willingness to place his clansmen into danger, Kaysān is genuinely loyal to his clan and country.

Since they are childhood friends and adoptive brothers, Kenran and Kaysān share a strong bond and both rely on the other in times of need.
