23화: 런던 출국 전 S.A 클래스 복원을 위해 케이가 히카리와 대결

23

Thanks to Aoi, the S.A class has been disbanded in order to force Kei to go to London. So that Kei 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. (Source: Wikipedia)
