Fullmetal Alchemist

This is the legendary manga [Fullmetal Alchemist], serialized by Hiromu Arakawa from 2001 to 2010. With its perfect plot foreshadowing, captivating characters, and profound themes, it's a masterpiece that's always mentioned when discussing well-made manga. The alchemist brothers, Edward Elric and Alphonse Elric, attempt to resurrect their deceased mother through human transmutation but fail. In the process, Edward loses his left leg and right arm, while Alphonse loses his entire body and has his soul bound to a suit of armor. The main story follows the two brothers as they embark on a journey to find the 'Philosopher's Stone' to regain their lost bodies. I believe most people know about it, but I'm posting it because it's a work that's close to the perfect standard of shonen manga.
