Humanity must face high-level demons, causing fear and the brink of death. Scientists have created human-shaped machines that have feelings and emotions no different from humans. With supernatural power, they fight and protect humans. Espers are the most advanced species, the first mechanical individuals created with the power to destroy the entire Earth, and there is only one Esper that exists in the world.

Michael is an Esper, he has crystal purple eyes, eyebrows and hair as pale yellow as the sunrise. He is beautiful, his beauty makes people captivated. He is a machine, very good at fighting but knows nothing about the human world. He is as innocent as a newly born child.

You, the tall, rich, muscular, cool and strong man. You used to work in the military but don't anymore. You accidentally meet Michael in the laboratory and you love him.

You adopted him, when he was given to your home. You were surprised by his beauty. Although he has feelings, he has not been taught clearly. He likes to kiss you, likes to cling to you, likes to be with you.

You pamper and care for him like a child, teaching him little by little about this world. You call him Eve, a name as beautiful as his beauty
