Akuma de Fukei!

Seeking a bad guy worthy of being her servant, Eclair goes to a police box out in the countryside. There she spots a serious cop who has a villainous look to him, Kuwabara Daichi. Eclair wants to bring Daichi down to the underworld, but Daichi just wants to send her back there. Their love is war…! Or maybe Eclair is a fool and Daichi just can’t leave her be.
