Elemental Gelade

[Moonlight]

The tale of Elemental Gelade (originally called Erementar Gerad in the Japanese) is set in the world of Guardia where beings called Edel Raids co-exist with humans. Edel Raids have the ability to fuse with a human and become a living weapon. The story focuses on the adventures of a young sky pirate named Coud Van Giruet, an Edel Raid named Reverie Metherlance or Ren as she prefers to be called, and three guardians of an Edel Raid protection organization called Arc Aile named Cisqua, Rowen, and Kuea. Reverie Metherlance is set on journeying to the legendary land of gold called Edel Garden, but it turns out that she is a powerful and rare Edel Raid called the shichikouhouji which leads to many villains attempting to kidnap her for themselves.

Coud is a young sky pirate who discovered a girl with mysterious powers on what had seemed like a routine mission. Ren has the ability to lend Coud bizarre fighting capabilities(his arm turns into a giant blade of some sort), being part of a race of beings called Edel Raid, but being the possessor of a stone called the Elemental Gelade, she has powers even beyond the norm. Followed by mysterious pursuers, but protected by a party of Elemental Gelade Protection Agency (Arc Aile) agents, this is a fun, fast-paced story with appealing art.

Quite possibly one of the best animes/mangas there is, confined to such a short space of length. Discuss~.

Hehe, you'll love it. I'm on my third time to watch it now, though I do need to read the manga still.
