The Symbiotic Relationship Between a Panther and a Rabbit

My name is Vivi Lapian. I am a rabbit from the prestigious Lapian beastfolk family. In the world of beastfolk, everyone is able to turn human when they reach adulthood. But for some reason, I'm the only one who hasn't been able to transform even though I've already reached the age of 18. Ashamed of my mere existence, my parents abandoned me in the Black Panther territory. Then, as if it were meant to be, I encountered a black panther who gazed at me with a pair of gleaming red eyes— "You're scared of getting eaten? Then cry more." "It's because your legs are short, you fat bunny." "I picked you up. That's why you belong to me." This... this isn't normal~!!! As if black panthers weren't enough, lions and wolves have started to show up too! In a gathering of savage beasts, of all places, will a baby rabbit like me be able to survive? The adventure of frail(?) baby Vivi— Project <Surviving the Savage Beast's Den> starts now!
