100 years ago, the war between humans and demons ended with a victory for humanity.
Defeated, the demons' numbers dwindled, and survivors were overwhelmed by the humans under the protection of the Goddess. Since then, demons have been destined to become human slaves at birth, and it's become commonplace for them to spend their entire lives serving humans.
Liebe was reincarnated into such a world as a demon. He died in an accident just as he was becoming desperate due to bullying. However, he was reincarnated into a world where demons were treated poorly. Liebe was also made a slave (pet) to the daughter of a frontier noble, and spent his days serving her. Even though he wanted to fight back, his slave contract prevented him from doing anything.
However, Liebe possessed special eyes that allowed him to see his opponents' weaknesses. Combining this power with magic, he developed a spell that temporarily repelled the slave contract. Since he'd gone to all the trouble of becoming a demon, he decided to become the hope of the demons... and become the strongest demon king!
This is the start of a rebellious fantasy about the rise of the weakest demon race!
