Ousama no Propose  

Saika Kuozaki, known for her stunning appearance, holds the title of the world's strongest mage. She possesses the unique ability to prevent catastrophic events that threaten global destruction every three hundred hours. Despite being mortally wounded, she passes on her powers and body to Mushiki Kuga, a normal high school student who stumbles upon her. Although Mushiki inherits her abilities, he lacks control over them. To save the world, Mushiki must attend a mage academy as Saika while concealing his true identity.
