Fullmetal Alchemist: Brotherhood, Made in Abyss Recommendations
Adventure world very original. Both gave two kids trying to find a parent and answers about themselves. There is even a tragic experiment story in both of them.
Both are fantasy and adventure anime with a strong underlying plot and world, focusing on the fantasy and mysteries of their respective worlds.
Both have outstanding storytelling and world building, along with the following similarities:
- Both have children as their protagonists
- Both of these protagonists are extremely knowledgeable and burdened relative to their age
- Both stories start because the protagonist want to help their family, who's in a dangerous and mysterious place
- Both stories have their dramatic and somber moments, while being relative lighthearted otherwise
Instead of just listing in dot points what similar, I'm just going to say one thing.
What both these stories have is a similar sense of adventure. Both have a group of characters working towards one goal. Not only are the character from both stories lovable and have in depth backstory, but the adventure it's is fascinating. The worlds they are both set in have lore that is not only explained extremely well but itself is just so damn intriguing. You know the world building is good when you as the audience can imaging thousands of other stories that can be told in the same universe.
