Verrier: Naughty Demon Servant

Kanenari, an obedient office worker, signs up for a maid dispatch service in a weak heart. It turns out to be a plot (?) by a demon who uses human emotions as her magical power! "My name is Verrier. I am a demon who feeds on disobedient emotions and will not bow to anyone." A romantic comedy of explosive emotions with a disobedient maid and devilish roommate!
