S.A Vol. 14 (manga)
The world of the SA class is turned upside down when Iori Tokiwa, a new student, transfers in and takes second place after Kei in the rankings, knocking Hikari down to third. But instead of resenting him, Hikari recognizes Iori as a kindred spirit as they both aim for the number one spot. As the two grow close, Kei must deal with a completely new experience--jealousy.
