No i’m not refering to a new bland male protagonist going to a new school. I’m not even talking about a cool male protagonist going to a new school.
Yu Nakamura I’m talking about somone so far from their normal life they may as well be on another planet.
Another name for this could be the normal guy in a bunch of misfits. Recruit from Arakawa under the Bridge is a perfect example of this. He is normal, very normal and yet because of one tiny thing he is forced to live with the biggest group of misfits of all time. The comedy is usually formed from the strange things the group does and the small changes that start appearing in the “fish out of water” which can eventually lead to the fish adapting to the new surroundings.
Katsuragi from The World Only God Knows also fits into this trope. He treats the real world as something to examine but not interact with which is his undoing when he is force to interact with real women. He spends so much time playing computer games he may as well be from another world.
The fish out of water character itself doesn’t necessarily have to have a certain personality as long as the person in question is very different from those around him or her it works. The character doesn’t even have to be the main character it can be a minor character or even a background character that has at least one spoken line.
