Avi Amon's mother, Sieste, comes to the Academy and asks her daughter to become the clan head. She refuses, as she wants to stay in the human world with her friends, and says that Sieste is not her mother. Sieste accepts her answer, but wants to test Avi. If she fails the tests, she will have to return to the Underworld. Elta Pruflas, her personal butler, will test Avi. Elta is enrolled in middle school.
Zekka goes to high school to ask Akeno for help. She cannot control Tensei after the "Eden’s Dual". Akeno dresses her in miko clothes. As a result, Akeno is unable to help and says that the problem can be solved by reducing her breasts. For this, it is worth contacting one girl who uses senjutsu. Grayfia suddenly teleports in. She wants to talk to Zekka about the butler Elta, as she doubts that he is really from the Pruflas clan (an "Extra Demons" household). Grayfia makes a contract with Zekka to arrive quickly in case Elta needs to be eliminated.
Zekka, dressed as a miko, returns to the middle school to change and sees Elta, who is also changing. It turns out that she is a girl. Zekka promises not to tell anyone, but Elta attacks with a knife. Zekka accidentally squeezes her breast, and Elta begins to cry. When she calms down, she reveals that her real name is "Elta Satanakia". Satanakia is one of the six houses that served the Lucifers. Officially half of these six houses were exinct.
Elta reveals that she dresses like a boy so that the Satanakia clan will acknowledge her. The house is predominantly male, and the family's demonic power is only passed down to the men. Girls are not appreciated. But if her last name Pruflas was false, then the fact that she is the butler Avi Amon is true.
Elta plays basketball in gym class, and her team wins. A fan club of girls called "Elta-sama's Ten-Meter Distance Club" has appeared at school. When Zekka approaches her, Elta takes advantage of this to avoid unnecessary attention. The fan club doesn't like Zekka being close to "prince" Elta.
It's lunch break. Schwertleite tells Zekka that she, Avi, and Lilebette have come up with a plan to make Elta happy and get gratitude from her in return. They call it "Operation EMO". The idea is to hold events that would make any middle school boy happy.
The first stage is to take Elta to the home economics club, the second stage is to take her to the shuriken club, and the third stage is to take her to the student council.
For the third round, Schwertlight thought of something erotic and told the student council member of the middle school that someone wanted to confess their love to her. Zekka entered the office, and it turned out to be the vice-president of the student council, Yoshika Minamoto. She thought that Zekka had fallen in love with her.
After the "EMO operation", Elta became interested in the handicraft club. In fact, only one student is active in it (others are ghost members) - second-grader Il Ragunt. She sends her crafts to competitions and sometimes exhibits them in a church from a neighboring town, since she is Catholic.
Elta and everyone else make crafts from sheep felt. Zekka made a figurine of Akeno with large breasts. Elta made a sheep, which was jokingly named Jamie J B Hunt.
A few days later, Elta reports that Avi is basically passing the test of her abilities and says that there will be a special exam. It involves taking part in an experimental RPG where players move around in an artificial space (spoiler: it's a parody of Azazel Quest from DX, and Life 3 will be all about it).
