What is the significance of October 3 for the FMA manga?

I think there are around 27 volumes of the FMA manga.

The FMA manga ended with a powerful conclusion. All the loose ends were tied up, and the characters' journeys came to a meaningful conclusion. It left fans with a mix of emotions - happiness for the characters' growth and a bit of sadness to say goodbye.

The FMA manga ended on a high note. The final chapters wrapped up the storylines neatly, and the characters' development reached a logical and emotionally resonant conclusion. It was a well-structured and memorable ending.

In general, FMA follows the manga to a considerable extent. However, for better storytelling in the anime format, some minor tweaks and additions were made, which still maintain the core of the manga.

Because the FMA manga has a unique story and great characters that are unforgettable.

No, as far as I know, there's no special significance.

The significance is that it shows real - life inspiration. It can motivate people to pursue their dreams despite difficult circumstances, just like the characters in the story did in real life.

FMA starts to diverge from the manga around the middle of the story. Some plotlines and character developments differ significantly.

Yes, it does. FMA Brotherhood is considered a very faithful adaptation of the manga.

Arcs in manga basically define the progress of the story. They can focus on character growth, a particular event, or a series of related events. They add depth and complexity to the overall plot. For example, a character's arc might show how they overcome challenges and change over time.
