Wataru's the academic ace among his classmates, but due to some bad luck and carelessness, he's failed the entrance exams and now has to enroll in a high school located on an island! On the boat trip to Promise Island, Wataru falls off, but he's rescued by a girl who turns out to be his sister. Actually, she's one of 12 sisters - 12 cute sisters that he's meeting for the first time, all innocently vying for his attention.

"Sister Princess - my sweet twelve angels" is a cheerful image CD soundtrack inspired by the PS2 game-turned popular anime series with endearingly beautiful and poppy tracks, featuring character-based songs performed by each of the original Japanese voice actresses.
