From the publisher:

While time passes peacefully, troubles begin boiling over. Bob hesitates over the choice he's made while Aya and Takayanagi feel tormented by their unrequited love. Then, Maya returns to campus with renewed resolve and Soichiro is put into confinement to begin the metamorphosis into the Black Dragon. The paths they've taken all lead to the Sohaku Estate and a confrontation with the "True Demon," Tetsuhito Kagiroi. While the fight goes down, Aya uses her Dragon Eyes to travel to the past. The battles change with time, but they are the paths that connect them all to their dreams!
