Mercury, Nina

ニーナ・マーキュリー

She serves as Rail Claymore's secretary and is a member of the intergalactic police force. Kind and polite to everyone, she eventually becomes friends with Millie later in the series. She appears air-headed and clumsy, constantly spilling the coffee she makes for Rail on him, and can destroy or short-circuit electronic devices merely by touching them. It has also been stated that Nina is the only Galactic Guardian capable of speaking the strange language of the people on the planet that worships chickens.
