Andou veranstaltet mit seinen vier jungen Damen einen spontanen Cosplay-Spaß und die kleine Chifuyu hat totalen Stress mit ihrer besten Freundin.
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.
安藤のもとに「小学校を辞めた」と千冬が訪ねて来る。とりあえず学校に千冬を連れて行くと、千冬の親友・九鬼円がやってくる。しっかりものの九鬼に千冬の世話を任せる安藤。放課後、いつものように部室にやってきた千冬を前に、安藤は千冬の異能を使ってコスプレ大会をすることを思いつき、全員でくじ引きで決めたコスプレをして遊ぶ。
いつもと変わらない様子の千冬だったが、実は日中、小学校で「高校生と遊ぶなんて変」と九鬼に言われ、喧嘩になってしまったことを安藤に話す。異能のことを隠したがために九鬼との関係がこじれてしまったことを知り、責任を感じる安藤。なんとか九鬼との仲を取り持とうと考えた結果、九鬼に自分はロリコンの変態で友達が居らず、唯一そんな自分と仲良くなってくれたのが千冬だったと嘘をつく。安藤といるのは千冬の優しさだったのだと納得する九鬼。また千冬自身も九鬼に素直な気持ちを打ち明けたことで、ふたりの関係は元通りになる。
적당한 이유를 만들어 조퇴를 한 치후유는 쥬라이가 있는 문예부에 찾아온다. 그러나 고등학생 사이에 혼자 이질적으로 섞여있는 초등학생, 치후유를 보고 사토미 선생님은 걱정이 많은 거 같은데...
Andou propodrá un juego en el cual él y las del club deberán vestirse con diferentes cosplay. La mecánica del mismo será muy divertida, aunque no para todos. Por otro lado, sucederá algo entre Chifuyu y Kuki que las hará distanciarse.
Jurai a porté Chifuyu sur son dos jusqu'à son école avant de rencontrer Kuki Madoka et de se rendre à sa propre école. Plus tard, le club a utilisé la capacité de Chifuyu qui permet de "créer un monde" pour se déguiser dans diverses tenues de cosplay, après quoi la tante de Chifuyu, le professeur Shiharu Satomi, mentionne que Chifuyu avait quitté l'école plus tôt.
Chifuyu va da Andou dicendogli "Ho smesso di andare a scuola". Per il momento, Andou accompagna Chifuyu a scuola, dove incontra la migliore amica della bambina, Kuki Madoka. Andou lascia Chifuyu nelle mani dell'affidabile Kuki ma, quel pomeriggio, al club di letteratura, Chifuyu inizia a raccontare cos'è successo quel giorno.
