Keima and Elsie have successfully conquered Ayumi and captured the loose soul. ──But they haven't completed their contract yet...!! Elsie transfers into Keima's class, declares that she's his little sister, and announces that she's going to live in his house as well! All for the sake of rounding up the loose souls in this city... Who holds the next loose spirit? And will Elsie be able to become...

The next loose soul was hiding in Maijima Academy's resident rich girl and daughter of the owner of a big company, Mio Aoyama. Keima and Elsie followed Mio home and discovered that she was actually living in a run-down apartment. Now that Keima knows Mio's secret, he offers to become her new driver! He continues to take care of Mio while enduring the abusive title of "commoner." And then one...

A short break from hunting down loose souls! Keima is finally free to toil away at his dating sims, but now there's a game that the "God of Conquest" cannot conquer...!? Keima begs (intimidates) Elsie into helping him conquer the buggy mess that everybody's talking about, "Crayon," the game with an ending nobody's ever seen. Elsie watches as Keima desperately tries to "save" the heroine Sora...

Maijima Academy is in an uproar because the current most popular orthodox idol, Kanon Nakagawa (who's actually a student there!), is coming for the first time in two months!! Keima is playing his games on the roof of the south building when he happens to run into Kanon. Kanon panics when she discovers that Keima doesn't recognize her, a national idol! Why is she so obsessed with drawing...

...I'm going to turn you into a fan! And so, Kanon sings on the roof for Keima. Keima treats her coldly in an attempt to learn what is troubling her, but Kanon is so hurt that she goes into a state of shock and her body becomes transparent! It appears to be related to the loose soul inside her...but as Elsie looks for information about Kanon, she learns about something that happened in Kanon's...

Kanon appeared to have cheered up, thanks to Keima's support, but then she disappeared right before the concert! The staff members are all flustered as Keima and Elsie desperately search for Kanon, but the pumped up audience doesn't realize that Kanon is missing. Meanwhile, a transparent Kanon is sitting by herself in a corner of the hall, unable to bear the pressure. What will happen to the...

Elsie tries to cook for her divine brother, but Keima is never pleased. This time, she tries to make a "self-propelled" lunch, but she gets yelled at again... Elsie is feeling down, but after some advice from Chihiro, she decides to try again! As she prepares to make a strawberry shortcake, she prepares sugar from hell and eggs of all kinds of colors. One of the eggs is...

Elsie's cake ended up blowing up! Keima yells at Elsie for lacking common sense, so Elsie goes to the library to study up on common sense in the human world. Maijima Academy's library houses an expansive collection of books. Elsie gets excited after finding a flashy picture book, but then she detects a loose soul in the librarian, Shiori Shiomiya! Shiori is a quiet and soft-spoken girl. It will...

Keima proclaims that books are no longer necessary in this day and age and the soft-spoken Shiori finally loses her cool!? As a result, Keima is able to hear how Shiori truly feels, but now there's an uproar in the library...? The "fortress of paper" that's protected Shiori from the real world is about to change...

The library has decided to dispose of a number of books to prepare for the new media room. Shiori can't bear the thought of her precious books being thrown away, so she sets up a barricade and holes herself up in the library. The members of the library committee pay no heed to Shiori's silent protests and prepare to storm the library and dispose of the books as planned. Shiori begins to falter...

Due to spending all of his time chasing after loose souls, Keima's room is filled with dating sims that haven't been completed... "Conquest mode" is activated to clear off the backlog of games!
