(New book, rating pending)
[One female lead, multiple male leads + strong female protagonist + apocalypse-era succubus fighter + all kinds of powerful men to collect and conquer + thrilling, indulgent romance + painless childbirth]
If the gods are gone, then I'll rise up on my own!
My plan was to conquer evil spirits, fight my way to the top, and reach the pinnacle of humanity. Beautiful men were just passing clouds, take them or leave them.
Who knew that even after escaping the partner match at eighteen, I still couldn't avoid the heavenly gift shoved into my hands!
After a second awakening, I became the first succubus in human history, born for love. Getting close makes me stronger, and I'll rise to even greater heights!
The devoted fan of a tragic, beautiful villain? I'll take him!
The insecure college boy who breaks out of his shell? I'll take him!
The stern, tsundere stickler for rules? I'll take him!
The taciturn, brilliant homemaker? I'll take him!
The white-haired, scheming sweetheart? I'll take him!
The dangerously possessive, crazy older brother? I'll take him!
(The order here doesn't match their order of appearance in the story.)
Take them all! Be happy and get stronger at the same time! They're all great help on my path to becoming stronger!
