Darling 2

Jun is a comic book artist who isn't afraid to put in a long day's effort at the office. He is, of course, the creator of obscene comics. Even though he's been assigned an impossible deadline, his unusual ability allows him to work at breakneck pace for the duration of the time he's awake. He's in luck since his assistant Miyuki is also his wife, and she's always willing to provide a helping hand when it comes to work.
