May wakes up one day in a fancy room with no idea how she got there. When some people she dosen't know arrive, they tell her she is the reincarnation of Capricorn and they need to work with her to use their Zodiac based magic. While initially very suspicious and sceptical, May soon finds that for better or worse, whatever she does has major repercussions on the internal politics of the secret Capricorn organization.
