Asano Naganori
In late medieval Japan, Kai is a half-Japanese, half-English outcast who lives in the Akō Domain, which is ruled by the benevolent Lord Asano Naganori. When Kai was young, Asano adopted him as a foundling. Asano's daughter Mika and Kai eventually fall in love, despite Kai being scorned by her father's samurai due to his mixed ancestry.
