SA・FA

Thanks to Aoi, the S. A class has been disbanded in order to force Kei to go to London. So that Hikari and his friends can remain together, Kei proposes a challenge to Hikari that if she wins, he will bring back the S. A. However, Hikari learns too late what Kei has done in order to bring back the S. A - he has already left for London for her sake.
