Butterflies on the Rainbow Series

Butterflies on the Rainbow Series (蝶 虹上 系列 Chō  Niji-jo Keiretsu) is a pentalogy by LEN which focuses on magic and other fantasy-themed things. The specialty of the series is that most of the characters are the 'reincarnation' forms of themselves (an example is Ayaka Higuchi who is previously known as Ayako Higuchi in the Yotokaido Series) and their are only a few new characters.

LEN added two other stories that focused more on Masashi and his way of life.
