[Master of all people + system + single female protagonist] (also known as accidentally entering the upper world: the roommate is a beautiful elf girl)
A simple doze off in class,
The high school math teacher waved his staff and controlled the blackboard eraser to fly in the sky
The lady who prepares food in the cafeteria only has a flying spoon left to shake the food at will.
Then he accidentally became roommates with a beautiful elf genius?
…
The source of all changes is only a disaster/opportunity.
What?
Is your magic one level higher than mine?
Look at my [Max Casting Strength], can you catch this small fireball with 500% power?
