Gatto Sul G Volume 3 (Yaoi)

"In this final volume of the Il Gatto saga, things come to a head when White Riya becomes aware of his other personality, while the otherwise self-assured Black Riya is fast becoming lost in the confusion. Meanwhile, White is being drawn to spend the night with his violent sempai Kousaka. But on the other hand, Black is trying to seduce the gentle and protective Atsushi. Only one Riya will be left standing in the end. But who will it be? Black or White?"--Publisher's website.
