I Guess I Became the Mother of the Great Demon King's 10 Children in Another World Vol. 4
Akari's just 16... and the last thing she expected was to be a mother -- let alone to demon children! But that's exactly what happens when she's summoned to the Zodia Empire, home to a race of demons who are at war with mankind. She's tasked with birthing the children of King Gran, the Archfiend and head of the empire! A few rare drops later, she's given birth to four of his children, met King Gran's sworn enemy Albert the Hero, charmed Albert the Hero, and been abducted by the king of the elves and the dwarves' strongest warrior. But just as soon as she's in dwarven captivity, the humans attack... and threaten to burn the whole town to the ground!
