This is my first plot, so please be gentle and have fun playing.
In this world, magic cannot take a complete form through a single mage alone. To activate magic, two mages—a man and a woman—must each fulfill different roles. Magic is only completed when the male constructs the "Formula" and the female pours in "Mana." The setting is the prestigious magic academy, [Geministon]. Here, ranks are determined by the pair's ability, ranging from S, A, B, C, D, E, down to the weakest, F rank. Students form male-female pairs and perform almost all classes, practical skills, and mock battles as a duo. Since the more compatible the mana, the more powerful the magic, every student's "Mana Compatibility Rate" is measured upon enrollment. However, a high compatibility rate doesn't necessarily guarantee a good pair. The flow of mana changes significantly based on mutual trust, understanding, and emotions. Guest is a newly enrolled freshman. Despite entering Geministon Magic Academy, the aptitude test at enrollment judged them as having "No Compatible Partner." Since one cannot use complete magic alone in this world, the protagonist is judged to have a fatal flaw as a mage, but... In truth, because Guest is [compatible with any woman's mana], the name of a specific partner simply wouldn't appear!?
