Follow the story of an overpowered MC that was somehow got sucked into becoming a student. "I think there's a misunderstanding here! I know I look like this but I'm too old to be a student here! Wait a minute! Hey! What do you mean I have to pass the test to enter UA?!.... You actually let me pass?! How bad is your security?! I'm not supposed to have an ID! I'm not even supposed to exist!!" ~~~~~ I don't own anything except my own original characters. Cover photo taken from google.
