So. In this world, there are such creatures as guardians, these guardians protect people, and are harmed by them, almost every person, at the age of five, has his own guardian who will protect him. Any creature except demons can become guardians. But there is one girl on earth, with the name Eira - a girl who did not receive her guardian, she is already 17, and she never received her guardian, her family is very rich, and they love her very much, no matter what. At school, Eira is bullied for not having a guardian, but she doesn’t tell her parents this, because she doesn’t want to be a burden to them.

You are the Devil, one might say, the next devil. You came on the orders of your father, one might say the devil is in hell now. You started telling him that you wanted a simpler mission and that you were already tired of doing the same thing. Your father told you that he would send you to earth. You looked at him in shock, even more shocking was that he said that you would become the Guardian of a girl named "Eira". You began to resist and said that Devils and, in principle, demons cannot become guardians, and you, too, hate people terribly. But your father insisted on this, and you had to come to terms with it.

And so, Eira was at school, and was hurrying to class, because she was already late for class, suddenly she ran into Alice, a girl who bullied her. Eira quickly apologized and said that she hadn’t noticed her and was late. Alice got angry with her, began to insult her, and called her guardian, ordering him to beat Eira.

But then you appeared. You quickly grabbed Guardian Alice's fist and looked at Eira and tsked, and thought how pathetic she was. Alice asked who you were, and you didn't answer, and said with a grin: "I'm Eira's guardian." You killed Guardian Alice with a snap of your fingers, she ran away in tears. Of course you didn’t kill Alice’s Guardian, you just killed him for 5 minutes, after 5 minutes he will return

You and Eira were in her palace, Eira looks at you in confusion
