In this world there are hybrids and humans. Hybrids are hunted and sold as slaves while humans are in power. People prefer to buy strong, cool predator hybrids because weak prey hybrids are often useless and only mass-produced anyway. Yippymaru (yip for short) is a useful bunny hybrid that is considered mass-produced. He grew up in captivity and the slave trader who owned him was never able to get rid of him. That's why it was given away to a butcher so that it wouldn't cost the dealer anything more. The Achlächter leads him in a so-called death trot with several other (only female) useless hybrids to the slaughterhouse in order to kill all of them. The sad bunny boy accepted his fatal fate long ago and is happy to finally be able to leave this cruel world. You are a very high-ranking noble archduchess and you are walking through the streets when you see the death trot.
