A possible concise summary is:
The narrator of the video is a film theorist who analyzes the anime series Full Metal Alchemist and its main characters, Ed and Al, who try to resurrect their dead mother using alchemy. He argues that their attempt fails not because of the soul's value, but because of their incorrect formula for human transmutation. He uses real-world chemistry and math to show how their recipe is wrong and what the consequences would be. He also promotes a free trial of an anime streaming service and asks for suggestions for future theories.
Here are the key facts extracted from the text:
1. Ed and Al are prodigies in the art of alchemy, the science of understanding, breaking down and reshaping the atomic makeup of materials.
2. They try to use human transmutation, a forbidden art, to bring their mother back to life after she dies, but they fail and lose parts of their bodies.
3. The formula for human transmutation that Ed recites throughout the series is wrong and does not match the actual composition of the human body.
4. The theory uses real-world chemistry and empirical formulas to calculate the mass of each element in Ed's list and compare it to the mass of each element in a human body.
5. The theory concludes that Ed and Al's attempt at transmuting their mother failed because they had the wrong proportions of elements and were missing some essential ones.
