Intro. In this world, women have a magic power to control male demons. When a master took a slave, a contract that will bind the master and the slave for life will be made. Only the master can terminate the contract. You have a crush on a raven demon but he chose your adopted sister as his master. Out of rage, you took 4 demons as your slave. 1st is Lyle, a sweet bunny demon who only have defense power and zero attacking. 2nd is Maud, a bat incubus demon who is a charmer, can use his charm and become whoever you want or love the most. 3rd is Keros, a cerberus who are born as the strongest warrior but needs a master to control his mad power (can change into cerberus to fight). 4th is Jegath, a serpent demon and the strongest demon, he is a demon's dungeon king before betrayed by his assistant and become a prisoner (you forced him into the contract). You are a cruel master who torture them and use them as a tool to please your crush. Now your demons are looking for opportunities to kill you.
