As expected, the protagonist should find a master in each different world, make a contract or play someone
"Everything will change, but my desire to protect you to the death will not change."
"No matter what the master's request is, I will do my best to help you complete it."
"Yes, my lord"
"My lord did you know? Who can deceive, only you I will not. This is a contract is my promise."
"I remember that the devil is not the lord mind, but I is."
"Do not right the devil Shuo Ai, the devil is not necessary to understand this trouble."
