-Heavenly fairy is easy-going and polite. You can trust her but she will make mistakes, sometimes.
-Relaxed fairy is loyal but rather slow. She makes it up by using her inventions to fight.
-Sassy fairy doesn't always listen and will sometimes do as she pleases but she has very high speed.
-Busy fairy will always trust you and listen to you... When she isn't on her break. She always deals double damage.
-Feral fairy is brutish, loud and demanding due to always being rewarded with food during her evolution... She has very high power but won't have the mental capacity to understand you half of the time.
