#### Episode List

| 1 | "Solve It, Then Think About It!" "Hodoite kara kangaeru!" (解いてから考える！) | October 5, 2016 (2016-10-05) |
| Tokine Amino is a regular 22-year-old young woman, working as the CEO's secretary for a company known as TEN2. Her good friends Yoshie Yamazumi and Kyouka Minakami, who both work at the front desk are also briefly introduced. As Tokine gets ready for work, all the while babbling excitedly about an anime director coming for a meeting, she unlocks the door to her room only to find herself in an inter-dimensional 3D world called Quizzun, where she comes across a creature she assumes to be a pig. The 'pig' introduces itself to the surprisingly calm Tokine as Hacchin, explaining that she has been chosen, and is thus unable to leave Quizzun unless she solves all the riddles given to her. With that, Hacchin rewards her with a special power to unlock truth. |||
| 2 | "They're After the Q-Stone" "Nerawa reta Q sutōn" (ねらわれたQストーン) | October 12, 2016 (2016-10-12) |
| With much complaint over her new look, Hacchin patiently explains that the remarkably revealing outfit helps her unlock her fullest potential, and after some quarrelling, Tokine sets to solving the riddles. With only three minutes left from her original five minutes time limit after bickering, Tokine quickly learns that there are no penalties given for wrong answers, and using her new powers, quickly solves the riddle by rearranging the pictures to their given titles, then piecing together the letters they spell. As she rejoices, Hacchin takes from her a green gem called the Q-stone, existing only in human minds when it experiences pleasure of an eureka moment. As promised, Hacchin lets her leave. |||
| 3 | "Vehicle" "No ri mo no" (の・り・も・の) | October 19, 2016 (2016-10-19) |
| After a busy day at work, Tokine manages to catch the last train at midnight back home, but while in the train gets transported back into Quizzun, along with the other commuters on the train. She notices that Hacchin was indeed telling the truth with most humans being unable to use more than 10% of their capabilities, and she once more sets to solving a new and harder riddle, this time with the commuters' innocent lives on the line. |||
| 4 | "There Are Other People in the Quiz?!" "Jibun igai wa kuizu" (自分以外はクイズ) | October 26, 2016 (2016-10-26) |
| With the simple instructions to "connect in order", Tokine nearly runs out of time but manages to solve it by using the colours and letters of the stations whispered by the dazed commuters, producing another wonderfully large Q-stone in the process. She then opens her eyes to find herself back in the train, and everyone is staring at her. Embarrassed, Tokine rushes home, and receives a text from Yoshie, informing her that she will be moving to Tachikawa, and requests her help, to which Tokine happily accepts. |||
| 5 | "Moving to Takros" "Takurosu ni o hikkoshi" (タクロスにお引越し) | November 2, 2016 (2016-11-02) |
| As Yoshie and Kyouka go down with one of the movers to help collect stuff, Tokine stays behind with the other two, and gets transported once more to Quizzun, along with the movers in a tow. |||
| 6 | "Quizun is Suddenly..." "Kuizu n wa totsuzen ni" (クイズンは突然に) | November 9, 2016 (2016-11-09) |
| Prior to Tokine's question, Hacchin tells her that Quizzun is triggered into being when potentially-high humans like herself experience excitement or sheer pleasure. As she looks at the clues carefully, she applies the colours of the animal blocks and the animals in English, while checking for the "space" between North and South, two words that the movers are constantly whispering. Tokine solves it faster than the previous one, as the answer was plain to be seen from the very beginning, and producing another Q-stone. After the tiring afternoon, to thank Kyouka and Tokine for their hard work, Yoshie treats them to dinner at a BBQ meat restaurant, where they discuss plans for the company trip to Minakami Hot Springs, a business run by Kyouka's family. In all their fun and laughter however, a strange couple sitting behind them is overhearing every word they are saying. |||
| 7 | "An Exciting, Fantastic Company Trip" "Harahara wakuwaku shain ryokō" (ハラハラわくわく社員旅行) | November 16, 2016 (2016-11-16) |
| During the company trip, the strange couple at the restaurant is surprisingly following them, confirming that they are employees of TEN2. At the hot spring, they meet Kyouka's younger sister Kyouko, and her friends from high school Hinata Takaragawa and Mamori Sonazawa. While stripping, Tokine gets transported back to Quizzun with her dearest friends, to face not a riddle, but a dragon. |||
| 8 | "What's Sengokushi?" "Izumi goku kokorozashi ttenandesuka?" (泉極志って何ですか？) | November 23, 2016 (2016-11-23) |
| Tokine successfully solves the riddle while avoiding attacks from the dragon by linking the colors of the girls' towels, hexagons, and hovering balls that change colour, while signalling the dragon's time to attack, and she syncs the dragon's words, once more in English with the letters on the colors. Returning to the hot spring, Hinata, feeling less shy towards her new friends, invites them to come to a pro-wrestling match with her as she has extra tickets. |||
| 9 | "Earth-Shattering Sound" "Karada ga furueru (kyokubaku)" (体が震える（極爆）) | November 30, 2016 (2016-11-30) |
| The girls have a great afternoon the next day. Apart from the exciting match, tea is held at Yoshie's lovely new house and they watch a movie at a nearby theater in the evening. At the theater, they once again encounter the strange couple, and the lady, Natsuko Yanagisawa, is revealed to be a former cabaret member who used her connections to get into the company. As Tokine grows excited over the movie, she is transported back to Quizzun again, along with all the people in the cinema, but this time, she is not the only one who can use her full abilities. |||
| 10 | "The Q Stone Starts to Grow?!" "Sodachi hajimeta? ! Q sutōn" (育ち始めた？！Qストーン) | December 7, 2016 (2016-12-07) |
| Natsuko can move, speak and think along with Tokine, who is shocked. As Hacchin appears however, he blurts out that Tokuyo Nazo is Natsuko's real name, and the two girls begin competition for completion of the riddle first. Both solve it at the same time, and they are released back into the real world together. |||
| 11 | "The Amazing Final Problem!" "Kandō no saishū mondai!" (カンドウの最終問題！) | December 14, 2016 (2016-12-14) |
| After the relaxing day, the girls return separately to school and work. The threesome then head to glimpse a spectacular light show after work. Things get caught up in Quizzun again, as another challenging problem crops up for Tokine to solve. |||
| 12 | "Hmm?! What Happens in the Last Episode?" "N? ! Dōyara saishūkai!" (ん？！どうやら最終回！) | December 21, 2016 (2016-12-21) |
| After hard thought and a wrong answer, the riddle is solved yet again, along with another Q-stone. For the first time after collecting it, Hacchin stays to talk to her, explaining that Quizzun is a world created by human insight born from Q-stones, a reason why he is constantly collecting hers. The energy in Quizzun is circulated here and returned to Earth, and the places where it has appeared before are known as power spots which have different effects on people like purity and good luck. As he leaves, Hacchin informs Tokine that a change will be coming over her, and bids goodbye. The next morning, Tokine wakes up to find the sky an unsightly purplish color, along with Hacchin by her bed, announcing that he has a present for her. |||
