A girl who forcibly invited Jing and Kir to solve the mystery of a treasure that would grant them immortality. Vermouth has a cheerful disposition and is rarely seen without her umbrella, likely due to her disdain for rain.
In reality, Vermouth is a robot powered by a perpetual motion machine invented by King Cointreau. She was on a quest to find a legendary minstrel to become the rightful successor to the King and his Eternal Water.
Vermouth chose Jing as King Cointreau's successor because of his casual and natural gestures. At the end of their journey, despite being a robot, she shed tears when Cointreau passed away after meeting Jing.
