Need an anime or manga?

[Onepiece_luffy01]

I want anime or a manga with the main character as a student where all the people around him thinks of him as a stranger even though he's not a transfer student but actually he is a very different person than everyone thinks.
If can I would like the main character has something he's/she's good at(something like sports or something)I already read horimiya and its good but not that popular.
