Preecha “Ka” Klahananong is a supernatural living in New York City. Her nickname “Ka” is shortened from “kà-nŏm”, which means sweets. In Hong Kong the english speaking members of the supernatural community know her by “Pancake”, which is also the name she tends to use among other english-speaking communities. She lives in the basement of May's Remedies, the shop of Ancient May.

Ka often wears a vibrant red Qipao, with her long black hair held up with two lacquered black wooden hairpins, each pin featuring a red tassel.
