Elemental Gelade is one of my favourite manga
ever, the main character is Coud Van Giruet a
rookie air pirate. when Coud one day goes
snooping around in the pirates ship he comes
across a girl Ren who is an Edyll Raid a living
weapon that reacts with a human to become a
fighting machine. Coud must try to protect Ren,
and help her reach the place she speaks about.
