Kuroko had been repressing her feeling for Mikoto, trying to move on from the painful unrequited love. Meanwhile, Mikoto also has been hiding unsaid sentiments for Kuroko. However, when the untrue tale of Railgun's brutal murder of an old man dominated the cyberspace of Academy City, Kuroko and Mikoto teamed up again to prove Mikoto's innocence. What will happen between the two?

There was a time, when Mikoto was kind, when her heart possessed humanity, and when her first response to problems wasn't to tear, to rip and to destroy. But that time is gone, when Kuroko applies her 'love drug'. Can she stop, before she's destroyed everything she had? Is Kuroko's good-will, enough to bring her back?
