1v1, two equally matched leads, a younger seme who seems sweet but has a dark side and is Cthulhu-esque (?), paired with an older uke who seems pure but is secretly cunning and is a magical girl (?)
Tianci, an outstanding young man of the 21st century with excellent grades and conduct, falls asleep and wakes up reincarnated in another world.
In this magical world, some people awaken special abilities before the age of eighteen and become ability users.
Tianci is now just a few days shy of adulthood. He had assumed he was destined to remain ordinary, but at the very moment he comes of age, a shooting star falls from the sky.
“Boy, make a contract with me and become a magical girl!”
