Akuma de Fukei!

In her desire to find the perfect evil man to be her slave, the devil Eclair traveled all the way from the netherworld to a local country town's police station. She set her sights on Kuwahara Daichi, an evil-looking cop. Eclair wants to do everything to tame Daichi, and Daichi wants to drive her back to hell. What a romantic battle... or at least, that's what it looks like. Actually, Eclair is completely useless, and Daichi can't leave her alone.
