Book four has the showdown between Jesus and Lucifer, and the lead singer from each band wants Aine! It makes for a fun show, and Jesus' head crooner has a few problems with his life and attitude in general. Still, to me, Aine isn't worth all the hulabaloo. But it's fun to watch what's coming next and I'm still interested in following this story for another round. And I like the way author/manga-ka Mayu Shinjo draws her pretty boys.
