Japanese Title: るくるく
Humans are a despicable lot, committing sin after sin, filling the endless boundaries of the underworld with tortured souls. Now, it would seem, Hell isn't so endless after all, and it has become dangerously close to filling, and then overflowing into the human realm. Princess Lucuha sees this imminent disaster and has a plan: save Hell by making humans decent again. Of course, the Angels can't simply allow Demons to roam freely on Earth, and they do their best to stop Lucu and her dastardly plans.
Suzuki Rokumon wakes up one morning to find the little demon girl, who can use her hair as appendages, preparing breakfast. In the living room he finds another strange demon, who claims to be his new Dad. Rokumon asks where his real Dad is and the demon tells him it is in the next room. Needless to say he's having a pretty bad morning. Thus begins Rokumon's strange new life, with Lucu and her demons, who according to her "want to save the world, and mankind."
