Ousama no Propose

Saika Kuozaki is a witch of unparalleled power and breathtaking beauty, serving as humanity’s sole defense against enigmatic entities that threaten to annihilate the world every three hundred hours. Her unmatched strength makes her indispensable, but even she is not immune to fate. When Saika suffers a fatal wound, she entrusts both her extraordinary magical abilities and her very body to Mushiki Kuga, an ordinary high school boy who happens to be nearby. Inheriting such immense power does not grant Mushiki immediate mastery over it. Though he now possesses Saika’s formidable capabilities, controlling them proves to be an entirely different challenge. To stand any chance of protecting the world from impending destruction, Mushiki must step into her shoes and enroll in a prestigious academy dedicated to training mages. His enrollment comes with a perilous condition: he must live his new life entirely as Saika. Concealing his true identity while navigating the complexities of a magical institution will test his limits. Surrounded by skilled sorcerers and looming threats, Mushiki must master his borrowed powers in secret before time runs out and the next cataclysm arrives.
