As Long As You Get Stronger, the Beast-Eared Girls Will Mate with You, Meow

Long ago, at the dawn of humanity in a distant parallel universe, the world was home to countless humanoid races: panda girls, dragon girls, catgirls, dolphin girls...

Their greatest wish in life was to bear children for the powerful kings of their clans. The mighty clan kings waged war against one another, killing and plundering. To keep these beast-eared girls from being wiped out by war, an incompetent man who had been reincarnated as a half-blood panda was born. The man who would one day be known as the Beast Emperor.
