Sasahito
Summary
From Manga.club: Ron Ron, the baby panda, was born with a crying voice exactly like a human. When he turned 6, he suddenly can talk like in human language, thus claiming for his own human rights. When the world granted his wish, Ron Ron was then adopted to Sasahito family. He might be a 6-years-old panda, but his soul is a 15-years-old male in puberty! This little pervert panda who deceives everyone with his cute face, what kind of extraordinary life will he experience in the neighborhood?
In a roundabout way he kind of is the MC's daddy; him seeding a bunch of mutant mandrakes randomly in the forest, one of which she seems to have been reborn into... kinda makes sense in a coincidental kind of way...
Or send her ass to a convent.
