@Noob_Gamer The photo of Kirisaki is the same from the high school.
The implication here is that the photo girl leaked it after Kirisaki became an idol to ruin her reputation again.
@WalDerWolf
Sorry for confusing you, i mean it's what she did in chap 34, seems to me that she is trying to keep herself in safe condition by telling trainer that Tamako is lying about those 2 gals cheating.
