Become the Strongest and Return to Kivotos

Please Ask the Protagonist in the Blue Files to Be a Male Student! ! ! ! !

I want to read a book similar to "Blue: I am Brother Atsuko". The protagonist is required to be a male student. It is required that the player has strong strength and the power he creates and has a system. Of course, if there are no above requirements, the most basic requirement is that the protagonist is a male student.
