well as i don't understand Japanese and there was no subs my understanding of it is limited, I enjoyed it anyways because I'm a big fan of the anime and manga.
they introduced a new character which i found interesting, ill be interested to know if they going to do a spin off from the manga with a completely new story line or if they are going to stay true with the manga, with a few changes obviously.
the one part i loved is when the water/liquid alchemist? used his own blood as a weapon.
well ed is a state alchemist so it may be a sub story which takes place between one of the many adventures he had during the anime, although the rogue alchemist which he is fighting is new so untill we get a fan subbed version i dont think were gunna find out if it is related to the anime or completely different.
