Mirei receives an elaborately-phrased letter from Jurai, intended to give her ability the name of "Grateful Robber", but misreads it as "Grateful Lover", misinterpreting the letter as a love letter and declaring herself to now be Jurai's girlfriend, leading the entire club, Jurai included, baffled. After having to deal with both Mirei's over-the-top affections and the jealous glares of the other girls, Jurai explains the situation to Mirei, who seems heartbroken from being turned down. As Tomoyo Kanzaki comes to cheer up Jurai during his moment of guilt, he explains he chose that particular name for Mirei's power so it would match the others and show that she was one of their friends. Afterwards, Jurai receives an e-mail from Mirei apologising for the misunderstanding and accepting the name he gave her power.

Jurai carried Chifuyu on his back to her school before he met up with Kuki Madoka and proceed to go to go to his own school. Later, the club use Chifuyu's "World Create" ability to dress up in various cosplay outfits, after which Chifuyu's aunt, teacher Shiharu Satomi, mentions that Chifuyu had left school early. Later, Chifuyu shows up at Jurai's house after getting into a fight with her friend, Madoka Kuki, who told her not to spend time with the Literature Club anymore. Things get worse between them due to Chifuyu being unable to tell Madoka about her powers, leading her to believe she likes them more than her. Jurai attempts his own dubious manner of trying to get the two to make up, but Chifuyu accomplishes this on her own by having Shiharu help her win Madoka a plush to match with hers. Afterwards, Chifuyu reveals that her wanting to quit elementary school was from a desire to skip grades and enter high school alongside the other members.

Jurai buys himself a guitar, which he risks in a game against Chifuyu. Whilst retrieving his bag later that day, Jurai learns that Tomoyo is trying to become a novel author, being surprisingly supportive. Tomoyo feels pleased the next day when she passes the first round of a light novel award, so Jurai invites her to lunch on the weekend to celebrate. As the two spend time together on what many would see as a "date", element manipulator Hatoko Kushikawa is shocked to see them together.

Mirei steals Chifuyu's ability when she uses it to protect Hatoko, before Tomoyo helps everyone to escape. Regrouping at a karaoke box, the group deduce that the Mirei they fought against was an imposter possessing her body. Jurai goes by himself to confront the imposter, tricking her into stealing his enhanced "Dark and Dark of the End", which only serves to burn its user's hand with a neverending flame that cannot be extinguished. This forces the imposter to return Mirei to her body, after which they use Chifuyu's powers to chop off the burning hands and send them to another dimension whilst Sayumi heals them. Following the incident, Tomoyo and Hatoko discuss their respective feelings for Jurai, before everyone returns to their everyday lives.
