Shichimiya is facing the hard fact that she's in love with someone else's boyfriend, and vows to do battle with and vanquish the enemy within once and for all. Rikka is aware of the presence of her emerging rival, but Yuta is clueless to the point of cruelty.

A mysterious girl has appeared who claims to be Mori Summer. She is very keen on fervent, little disciple, Dekomori. Nibutani is outraged that anyone should have the gall to steal her fake identity, but then decides to give up and use this precious opportunity to wash her hands of her dark history and also of her annoying freshman, Dekomori.

Rikka and Yuta start their speical day out together in Kagoshima, only to run into a certain crazy magical devil girl who has become stranded without her bag.

Rikka makes club uniforms for everyone, further humiliating Yuta; tension between Nibutani and Dekomori continues to grow. Isshiki receives a love letter, but his plans hit a snag before they even begin.

Yuta begins to worry after it becomes apparent that Rikka may not come back. Sanae ditches her Dekomori persona to follow suit with Rikka, while Kumin "inherits" Wicked Lord Shingan's powers. Yuta can't bear being without Rikka and sets off to find her.

After recovering from adolescent delusions, Yuta transfers schools to begin anew. As he tastes the succulent fruit of normalcy, Rikka Takanashi discovers Yuta's delusional past and declares that they are soul mates, which makes things anything but normal.

Yuta wants to crush on the beautiful Shinka, but Rikka's antics prohibit it. A visit to Rikka's house reveals how delusional she really is. Her eclectic collections are almost stranger than her behavior! What’s worse: Rikka's sister knows about Yuta's past!

Yuta tries to decide what club to join, but Rikka is already a step ahead of him. She creates the "Far-Eastern Magic Society" and manages to rope in two members. Given a provisional club status, Yuta revokes his membership...until Shinka joins the club, too.

Rikka and Yuta face their low grades, and their club is fingered as the culprit! Rikka begins a new battle with her latest opponent: math! Meanwhile, Dekomori and Nibutani continue to butt heads.

Yuta is puzzled that Nibutani wants to join Rikka's club. He wonders if she could really like him back, but the answer he gets isn't the one he imagined!

After refusing to face the truth about her father, Rikka "retreats" to her home with Yuta in tow. Makoto is finding it tough to figure out his feelings for Kumin, and Yuta shares a night together with Rikka that impacts them both in a very meaningful way.

Rikka and Yuta are unsure of where they're headed, and each gets some advice from a friend. Rikka's sister reveals her intention of studying the culinary arts in France, and asks Yuta to help her with Rikka. Through their own special ways, Yuta and Rikka confess to each other.
