Well, I don't really want to get you to watch an Anime when I've only seen the first episode...and it probably won't seem that good the way I'm about to explain it, lol.
All I know is that there's this girl named Amu who is known to be "cool and spicy" by her friends because of her behavior, and she isn't really like that on the inside. She wishes that she could be her true self, and the next morning she wakes up and finds eggs in her bed (funny scene, lol). So far, I've seen one of these hatch, and they seem to be her personalities.
I don't want to say anymore or I might spoil the whole first episode, lol. The best thing I can suggest is to watch the first episode, and see if you like it enough to keep going. It seems kind of cute and funny, so I naturally like it. :3
I don't change my avi that much either. Maybe 4 or 5 times over 2 years. What did you have before the pink name? I'm trying to remember...
