World of Ten Billion

Will Heaven triumph or will the fairies conquer all? A siren prince, Heaven has it all—talent, beauty, and powerful abilities. But one day, the fairies attack and he's forced into hiding, dressing as a woman and selling snake oil to get by. The surviving sirens dream of revenge and the return of their royalty... but Heaven's got other plans.

Haven, endowed with innate talent, beauty, and special abilities, was the pride of the Siren royal family, garnering great expectations.

One day, due to a sudden turn of events, Haven had to endure a significant event involving the destruction of her family and race at the hands of a fairy. Avoiding the fairies who might still be searching for her, Haven disguises herself by cross-dressing, concealing her identity as an ordinary human herbalist. While everyone dreams of the resurrection and revenge of the royal family, Haven’s thoughts seem to diverge a bit.
