Overal rating: Funny series with it's share of funny songs ^_^. In the character songbook, all the songs are sung by the Seiyuu of the four main characters. I love it!
 
 
 

1. Angel Blue (Airi Version)	OP theme that's lower than the original for Airi (Michie Tomizawa). I like the original better. It's one of my favorite songs and I don't have it!!!!!!!AHHH!!!
