The Nameless Demoness

A rabbit turned into a demon and had no understanding of the human world. He had to learn all human behaviors and knowledge, especially palace fighting. If it weren't for cheats, he would have probably died several times. People's hearts! Even demons are difficult to see through and master. The protagonist, the rabbit demon, has no goals of her own in life and does things based on her preferences. However, she remembers the aura of her benefactor and has never forgotten it for thousands of years... Looking forward to the follow-up.
