蚊に転生した俺、女帝の契約獣だった件

Reborn as a mosquito with an evolution system, I bit a sleeping beauty to level up, only to discover she's a reborn empress mid-ritual, summoning her divine beast. Now her entire fortune bought… me. She's horrified. I'm a mosquito. Together, we're unstoppable. But who truly rules this bond, the empress, or the pest she never chose?
