Erica has the mysterious power to hear the inner thoughts of people. While working as a maid at the castle, every night she hears the voice of someone suffering from fatigue... The owner of the voice is none other than the invincible Emperor Julius, hailed as a superhuman. When she begins to help him sleep in order to restore his peaceful daily life, she hears a lustful cry: "I love you, Erica, I want to put it inside you!" This time, she hears a lewd cry of desire. Could the usually cool-headed Julius really do something like this...?! A slightly erotic love story between the out-of-control (or perhaps a bit out of character?) Emperor and his loyal maid!
