All Airu for me. The moment I saw her in chibi form and saw her in the beginning, I felt like she carried this games release with her cute attitude and witty comments. I kept wanting to play to see how she develops her relationship with the player and how she develops as a character herself. Later on the cards, game play, and hentai did make it a pretty good game to play. I could honestly say if Airu's chibi wasn't there and if Airu never existed, I would've probably dropped the game due to the stories getting boring since the player and Airu set up the seduction and stories by talking about stupid stuff then get down to business. I mean hentai is nice, but it's all about how you deliver the game and present it to me that keeps me wanting more.

For how I found PPS, I saw an ad for Aegis on a website that had If My Heart Had Wings: Flight Diary torrents.
