There are certain themes that run through anime and manga that are so universal that they have a way of evoking the same emotions in everyone. Anime, for example, is a perfect example of the power of story. It’s about a bunch of people, and they are all trying to escape something that is all too familiar.
The most common theme of anime is the same: being a character who gets what you want. A character who’s not what you want is like a character who’s not what you want. The theme then goes away.
In the case of anime, this theme is “the unknown”. This is what makes the characters and plot so compelling. The thing about Anime is that its all about the unknown, and the characters in it are always trying to get it, but the knowledge they have about what they want doesn’t always help.
