When do you have freedom?
This is the philosophical question explored in Isekai Herald.
It starts out by questioning whether we can have the freedom to choose when we are being exploited.
In continues with the question of whether we are being exploited if we are forced to work to be able to eat.
It questions whether the changes hormones play are a part of us, and is it freedom to be with or without them.
Later in the series it questions freedom of responsibilities, and movement.
Finally it questions if control of the laws of reality and being the most powerful in the universe is how far we have to go to achieve freedom.
