The setting of the characters are based on the authors' fantasy. Those kind of people won't really exist in reality. Especially their dramatic facial expression and costumes.
Why are the stories interesting?
The reason that stories are interesting is as same as why the characters are attractive. Because the story will never happen in reality. Characters can do things we aren't able to do, like having super powers or doing dramatic actions.
Why did you learn such a life lesson? Is it related to any character?
In the third year of my junior high school, the pressure of having tests almost crushed me. Then I found when I was reading comic books, it was the only moment that I could forget all the unhappiness. My favorite comic book, Gintama, is a comedy always makes me laugh. The main character is also the one that I identify with the most. He is very lazy and is mean to others, but when someone is in need he will definitely help him or her. No matter what kind of mess he gets into, he will find a way to solve it. This comic book gives me a lot of courage to face my difficulties.
Why are their personalities changed? Is that related to any character or any story?
They became confidence to themselves because after releasing their pressure and becoming friends with those who have the same interest, can gain recognition from others.
