I'm not reviewing just this DVD but the whole series; the series has to start somewhere- the first DVD of course!
"Set in a fictional 19th century England, D.Gray-man is the story of Allen Walker, a 15-year-old boy who roams the earth in search of Innocence. Washed away to unknown parts of the world after The Great Flood, Innocence is the mysterious substance used to create weapons that obliterate demons known as akuma." (taken from the blurb of the manga). The Millenium Earl creates the akuma by visiting someone who has lost someone close to them and offers them a chance to bring them back to life. He creates a metal skeleton which is then ordered to kill the person wishing to resurrect them and live as them. They can transform into their natural state (a big metal thing with tons of guns sticking of it, well the Level Ones anyway)and kill. That's where the exorcists come in- to get rid of the akuma. I won't go into the characters because yu have to watch it to find out!
I can not recommend D.Gray-man enough as it is my favourite. You have to check out this anime and buy the other DVDs because you will not regret it. It contains action, comedy, romance (not that much but it is in a comedy way), fantasy, and a bit of horror as well, but if I can watch it then you won't be scared (HATE HORROR!).
