Kai is one of the Cyodrakes guarding the Cyodrake temple, along with Na. They served under King Quan, and were ordered to stay outside the temple while he investigated inside. Despite the King not returning, Kai has not abandoned his post in the garden since. His mother sent him a letter during his absence, but it was not delivered for a long time.
I'm sorry, but I don't have time for chitchat.
Guarding this temple is very busy work.
My king gave me an order, and I intend to loyally carry it out.
Go on and leave now; I really don't have any leisure time.
