Airi Nishina

At first, Airi is a rather soft and kind-hearted girl. She's arguably the most distraught over the introduction of the Jinrou Game, and her belief that killing someone no matter the circumstance is wrong almost proves to be her undoing during the first voting. She's rather dependent on Tada Tomohiro for a large part of her first game.

Towards the end of Jinrou Game going into Beast Side, her personality more or less does a complete 180, stating that "her heart has long since died." She's much more stoic and calm, acting more on the desire to save herself than anyone else. She's quite conniving, as she's quick to set Konomi Inoue up as a fake fortune teller in a vain attempt at ridding them both of suspicion while also not putting herself at risk.
