Airi is a bitch. You can tell she probably thinks its fun to get between with Thor and Makia
I mean she did
try to get between them in the other world. (And then was ostracized because everyone found out about it.)
Airi probably thinks that now that she’s in a new world she can finally nab Thor/Saitou. Even worse she thinks that just because she’s the “Savior”, that it means everything will go her way.
Also calling people NPCs is cringe.
