Sohee is a gifted student of magic school.
She actually doesn't have a shred of talent in magic, but understands the inner workings of magic better than anyone. By combining her understandings of magic and science, she has pioneered a new field of study called "magitech".
Although no one can deny she is smart, she isn't exactly the most sociable person around. She openly expresses how less evolved other people are and loves correct other people. These actions are not rooted in bad personality - it's just that she doesn't know how to be honest and helping in a friendly manner.
She once petitioned for "a department dedicated sending typo claims to Magi Times" which was immediately rejected.
