Jinkai was the leader of the Black Dragon Group and one of its four grand masters. He attempted to use the Moon Bird Recipe along with Retso in his Dragon Plan. In order to regain the Moon Bird Recipe, he sent various cooks to challenge Hai Yo but they were thwarted repeatedly.
After Retso was defeated, he would challenge Hai Yo personally. After losing to Hai Yo in a cook-off and hearing his impassioned plea, Jinkai regained his pride as a chef and abandoned his Dragon Plan.
