|Shou Hamura, who carries the blood of the white-winged clan, transfers into Yuusei academy, a school sitting on top of a small hill where dormitory lodging is mandatory. There he meets his twin younger brother, Kai Misonou. Shou had been searching for his twin brother, as they had been seperated since they were very young, but Kai has no memory of Shou, and is wary of him because he seems to know all about Kai`s childhood. Kai denies that they are blood relatives.
then, with a great rumbling a fissure opens up in the earth before them, and Shou jumps in to save his friend ...!
The cogs of time have begun to move around Shou and Kai, and they will no longer allow either of them to lead peaceful student lives.
