Ruru, being the youngest of the group, is a rather spoiled girl. Her hairstyle and pigtail holders represent a frog&#039;s skin and eyes. Ruru died of being too cold, so she is afraid of cold stuff. Her spoiled behavior has earned her the ire of Gou and Gai whenever she does something that contradicts their activities (in Gou&#039;s case, she insisted Goro read her a story when he hadn&#039;t eaten breakfast and in Gai&#039;s, she changed the channel while he was watching an anime), to which she replies that she only obeys Goro which causes them to break into fits which prompts at least Shin to restrain them. Ruru is in the junior rank. Her name means Pearl. Her color image is yellow-green.    (Source: Wikipedia)

Goro's down on his luck. He keeps losing jobs and has little money. One day he meets a fortune-teller outside of a pet store who predicts that his luck will change. That night three girls appear in his appartment claiming to be his guardian angels. Soon a total of twelve girls appear to help him, each one a reincarnation of a deceased pet once owned by Goro.
