Wistalia, Zen

ゼン・ウィスタリア

The second prince of the Kingdom of Clarines. He is in love with Shirayuki and has told his brother, Izana, that he wishes to make her his wife.
Zen is an excellent swordsman and has a penchant for exiting through windows instead of doors and jumping down from high places.
As a young child, Zen built up an immunity against various poisons by exposing himself to them in specific controlled doses, causing convulsions, fever, and difficulty walking, to name a few. These results were carefully documented by his doctors.
