I love this song, it is one of my favorite songs. The song is called Brat'ja and is played in English, Japanese, and (mostly heard) Russian. In English it is heard by the voice actor of Edward Elric, Vic Mignogna, and in Japanese it is played by Romi Paku. I have the Englosh version here and how it depicts the story line of Fullmetal Alchemist.
Disclaimer- I do not own Fullmetal Alchemist or the song Brat'ja
(Ed's verse)
How can I repay you brother mine?
How can I expect you to forgive?
Clinging to the past I shed our blood,
and shattered your chance to live.
Though I knew the laws I paid no heed.
How can I return your wasted breath?
What I did not know has cost you dear,
for there is no cure for death.
Edward and Alphonse only wanted to see their mother's face one last time. Even for a split moment. When they attempted Human Transmutation it ended terribly. Edward lost his leg. When he looked around, there was no sign of Alphonse.
"Al? Al? Where are you?" When there was no answer, Ed didn't know what to do. He thought he had lost the only one he loved most. He knew it was his fault.
(Ed's chorus)
Beautiful mother, soft and sweet.
Once you were gone we were not complete.
Back through the years we reached for you.
Alas, twas not ment to be.
And how can I make amends,
for all that I took from you?
I lead you with hopeless dreams.
My brother I was a fool.
Edward crashed the only full suit of armor to the floor. He removed the helmet and looked inside. It was perfect to house a soul. Edward drew a circle he had just made up out of the blue. It was drawn from of his own blood. He drew the circle on his legs, on his chest, and on his forehead.
"I'll give you my leg, arms, or heart. So give him back... He's the only little brother I have!" Edward cried into the darkness. Then he activated the transmutation circle. He only hoped it would work. He only hoped Al would forgive him and not rub it in his face when he awoke to find the Transmutation backfired. Edward now realized how foolish he had been.
(Al's verse)
Don't cry for the past now brother mine,
Neither you nor I are free from blame.
Nothing can erase the things we did,
For the path we took was the same.
No matter how many times Alphonse said he forgave Edward for what happened, he knew his brother didn't believe him. He had made the decision to do the transmutation as well, so he was as much to blame as Ed. Alphonse only lost more then Ed….
(Al's chorus)
Beautiful mother, soft and sweet
Once you were gone we were not complete.
Back through the years we reached for you.
Alas, twas not ment to be.
My dreams made me blind and mute,
I longed to return to that time,
I followed without a word.
My brother the fault is mine.
Al knew he could have stopped the Transmutation when he had the chance. He knew that if he spoke his mind and told Edward he thought it was a bad idea, Edward may have rethought his actions. But Al was silent. He never spoke what he thought should have been done. And he kept those words hidden from Ed because he knew it would upset his older brother.
(Both)
So where do we go from here?
And how to forget and forgive?
What's gone is forever lost.
Now all we can do is live.
Ed and Al were now fifteen and fourteen and they were looking for a way to restore their bodies. They only hoped that they would find a way….
