The concept of this idea is a bit complicated practically almost all the characters are nerfed

Satella when invoking subaru irreversibly causes people to be unable to do magic by conventional means

points need to be clarified

1: People can't use magic and the authorities have been weakened

2:Divine blessings have not been affected

3: The only way to use magic is through spirits

Also some characters whose physical strength decreases because I have the theory which explains the reason why there are people who have superhuman strength.

It consists of prana strengthening and reinforcing the muscles of the inhabitants of the world of re:zero, giving them strength and resistance greater than average.

I'm not saying that everyone is strong, but if they train a normal routine to be in good physical condition, they would have the strength to train for years.

Elves, onis and certain demi-humans will maintain their physical strength

If you were to summon someone and give them the ability to prevent certain events but not the strength to deal with them, you have two options: make them strong or make others lose their strength.

Do not believe it?

If you have read this far thank you for taking your time

Comment what you like that you would add to the idea

Without more I say goodbye
