If you have read or seen One Punch Man and are familiar with the character of King then you know what I am talking about
Basically a book where main character is weak but he just happens to be in right place at right time and so everyone thinks that he is very powerful.
Bonus if the main character is not aware that he is perceived as an omnipotent being.
Genre could be anything but nothing dark I am looking for a light hearted comedy book.
Thanks
