spiral has a very detailed story line.and its really interesting. ayumu narumi he's a very curious young boy and smart at that. when ayumu's brother left saying that he is going to persue the mystery of the blade children ayumu got mixed up with all the situation going on about the blade children. ayumu's brother told the blade children that ayumu can change the horrible fate that the children hold. i dont have a lot to say about spiral eccept that it is truly a wonderful anime. and i hope the reader does too.
