Transferred to the Gyaru Academy(2017)

Black Gakkou ni Tsutomete Shimatta Sensei

Sadamichi Imada has always dreamed of teaching at an all-girls school—a wish that comes true when he's transferred to Kurosugi Girls Academy. But there may be a teeny-tiny problem... his class is packed with nothing but bronzer-abusing gyarus! He barely has time to process a decade of gyaru-inflicted PTSD before problem student number one—the bubbly (and low-key horny) Mariko Kuroi solicits him for a quicky after school, and the other girls are quick to follow! Can Imacchi be professional in these uncharted waters teeming with thirsty thots, or are they going to drag him down with him!?
