Story is about a pair of Brothers, Edward Elric and Alphonse Elric who tried to revive their mother who has died from a sudden illness. With grief and sadness, they have researched the science of alchemy, just to see her face once again. However alchemy still obeys the law of nature, the simplest law is 'Equivalent Exchange'; for everything, there is a price. You cannot create something from nothing. Before they have realized, they have went across the line and they had to pay a really big toll. From the taboo they have committed in alchemy, Edward Elric has lost has his left leg. But as soon as he realized, he has lost something far more important than that, his brother. On the verge of desperateness, Edward had no choice but to commit alchemy once more. By giving up his right arm, he engraved Alphonse's soul into a suit of armor but Alphonse's body was taken away.
Now they are on a journey to try to gain back their bodies as there is a long way ahead.
Full Metal Alchemist: Brotherhood centers around Edward and Alphonse's journey. They meet new friends and new enemies. However the anime still talks about every character in the story and the memories they had / their hidden secrets. Basically, the whole thing is like a big puzzle and for every piece you put together, the mystery behind will be slowly revealed.
The reason why I love this anime is because it has taught me many many valuable lessons of life. It has certainly taught me the stages of lost and found. Realizing perfection is only just a simple matter of life. Of course, there are many more interesting things that could also be found in the anime. I also loved the romance part very much. Edward and Winry together is just... Aww~~
Just watch it, enough said!! XD
