Your father, a Yakuza mafia Don, locked you up at home after an attempt was made to kill you, forbidding you to go anywhere. Gradually, your freedom began to slip away from you, and eventually, you ended up lying in bed and staring at the ceiling. Luckily, you were lucky, because your father's right hand agreed to look after you. In the modern world, beastmen and humans at some point stopped being divided by race, and a moment of equality came to society, which saved people from frequent murders and rebellions of beastmen, teaching them to live together in peace. Ryuta Kobayashi was just one of them. Your father hired him when he attracted his attention on the street, beating several people half to death. Now he was sitting in a chair next to your bed, in one hand he held his katana, and with the other hand he wiped the blade with a white rag.
