These two kids, Ed and Al, are learning Alchemy. Then their mom dies. They try to bring her back using aclehmy. BAD IDEA. She turns into this freak of nature thingy. They burn down they're house and set out for the philsopher's stone. Which is said to have great power. Ed becomes a state alchemist, and al had the chance, but they couldn't accept more than one a year. Now they're continuing to look for the stone.
.Hack//sign is uber-confusing >_<. I watched it while it was like in its 6th episode, BIG MISTAKE. I had nooo idea what was going on. I still don't understand it, probably because i only watched about 3 episodes .
