FUCKING AIRY, that absolute Bitch, and I do not say that lightly.
lets list all out everything she does
1.) Impersonates a Guardian Angel to trick and deceive Agnes and Co
2.) Destroys The Crystals to destabilase the World setting it on a path towards destruction
3.) Kills The party and a lot of other people to achieve all this in brutal and sadistic ways
4.) The first 3 again, repeated billions or even trillions of times
5.) Callous disregard for the wellbeing of all others except for herself
6.) Gladly, GLEEFULLY, does all this why? Because She felt like it, not just in service to her boss Ouroboros, who is just as callous, cruel, and selfish as her
it is because of this game that I now instinctively distrust cute little helper characters, the game itself even tries to warn you about her itself on the title screen with changing the subtitle from "Where the Fairy Flies" to "Airy Lies" I don't think any media I ever interact with after that game will have a better or more hateable twist villain. Yes the game does have pacing issues starting in chapter 5, but man that Finale makes it mostly worth it.
But seriously Screw Airy: That Lying, Backstabbing, Motherless, Creature deserves to rot in the deepest pit of hell for all eternity and then some.
