Yamada-kun and the Seven Witches

The episode opens with Yamada being scolded by the teachers for his poor grades. Shiraishi comes by delivering the class journal, and Yamada is admonished to be more serious about his studies just as she is. Later, he passes Shiraishi on the stairs, and as they glare at each other contemptuously, he trips, falling down on her. When Yamada comes to he is in the infirmary, and he finds that he is in Shiraishi's body. Eventually he finds Shiraishi who is likewise in his body, and they agree to meet after school to try to do something to return to their own bodies. During the school day as Shiraishi, Yamada learns that the beautiful honour student's life is not without its problems, as she's being bullied. While he is still in her body he gets it into his mind to help stop people from bullying her. He tries to attack one of the bullies, making as if to punch her but intending to stop just short of hitting her, but Shiraishi in his body interposes himself and gets punched instead. This is enough, however, to make the bullies believe Shiraishi is no longer to be trifled with. They attempt to return to their bodies by falling down the stairs as before, but this doesn't work, but eventually they figure out that the body swap is effected by a kiss. They attempt to use this strange power to their advantage, but one of the student council vice presidents, Miyamura, figures out what they are up to. It turns out they can swap bodies with anyone, and he provides them with access to the former Supernatural Studies club room. A girl appears in the club room, asking if the club has been reformed and requesting to join.

Itou Miyabi eventually convinces the three of them to let her join the club. She turns out to have a bit of a mania about supernatural phenomena and produces a lot of junk that are supposedly supernatural artefacts. Her presence puts a bit of a damper on Yamada and Shiraishi's plans to use the club room as a secret place to perform their body swapping. Eventually, however, she catches Yamada and Shiraishi kiss, and infuriated, she begins to spread rumours around the school that the two of them are dating. In an attempt to undo the damage, he tells Itou the truth about the body swap power, and performs it on her to prove it. It turns out that Itou is known for spreading tall tales and no one really believed her. It turns out that she left the school in Yamada's body in an attempt to intimidate the punks who duped her into buying the fake supernatural artefacts, but it turns out that even in Yamada's body she is unable to fight them off. Yamada shows up in her body and manages to beat up the punks. This earns him Itou's gratitude, and her fascination at experiencing a true supernatural phenomenon. She has them experiment systematically with the body swap powers.

Itou attempts to make the Supernatural Research Club into a real club of sorts, requesting funding from the student council. The student council president Yamazaki is unimpressed by Yamada's threats, nor charmed by him when he comes to see him in Shiraishi's body. Inexplicably, however, he sees through the ruse, realising he is still talking to Yamada, but offers them a deal to provide the club with funding. He tells them how Shiraishi, despite her excellent performance in school, refuses to enter college after graduating. He wants to know why and to convince her to do so, as it would be a disgrace for the school for their best student not to go on to higher education. One day, Yamada swaps bodies with Shiraishi while she is very sick, giving him a chance to see her house and find out why she refuses to go to college. He realises she is a sad and lonely girl. He manages to convince her to go to college after graduating after he says he plans to go himself as well.

It is the school trip, and Yamada and Shiraishi swap bodies for most of it, so she can continue studying, leaving Yamada to deal with the business of socialising with the girls. Eventually he convinces her to swap back, and Odagiri Nene, Miyamura's main rival to becoming the next student council president, attempts to blackmail him with a pictures of him (actually Shiraishi in his body) rooting through Shiraishi's underwear. She tries to get Yamada to convince Shiraishi to not attend the mock exam a couple of days later. He tries to use the body swap power on Odagiri in an attempt to delete the incriminating photos but finds that the power does not work on her. After kissing both Itou and Miyamura to test, he finds that he is no longer able to swap bodies. After they get back from the school trip, he finds that Itou and Miyamura have fallen in love with him. It seems that he lost the power to swap bodies and instead charms people whom he kisses. Kissing Itou and Miyamura cancels this power again. They realise that the change happened right after he kissed Odagiri.

Yamada, now possessing the ability to charm people he kisses, constantly puts off kissing Shiraishi, fearful that this new power he has will affect her. He seeks out Odagiri, attempting to settle things with her, instead chasing off some of her flunkies, who seem to be under a similar influence as Itou and Miyamura had after Yamada kissed them. Odagiri however, also seems to be similarly in love with Yamada, much to the consternation of her supporters. Eventually Shiraishi convinces Yamada to kiss her, warning her about possible consequences, but instead their bodies swap as before. They deduce that the power to swap bodies is innate to Shiraishi, just as the charm power is innate to Odagiri, and Yamada has the ability to copy the powers of those he kisses. Odagiri and Igarashi Ushio, one of her supporters, see the two of them kiss, and this devastates Odagiri who is still under his spell. Igarashi used to be one of Yamada's friends but they had a falling out after he got Yamada suspended by covering for Odagiri, whom he is in love with. They eventually work out a deal with Odagiri, getting her to delete the incriminating photos in exchange for undoing the charm powers. Igarashi also provides them with some of the notes of the previous Supernatural Research Club before it was disbanded, describing the existence of seven "witches" in the school, Evidently Shiraishi and Odagiri are two of the seven.

The Supernatural Research Club is trying to find the second volume of the notebooks left by their predecessors which describe the other witches. It is supposedly in a locked storage room kept by the teacher who is conducting the supplementary lessons, which Yamada has to take along with a few others, including a very shy and soft-spoken girl named Otsuka. Yamada swaps bodies with Shiraishi, and after his performance seems to markedly improve Otsuka kisses "him". This leads Shiraishi to suspect that Otsuka is yet another witch, so she has Otsuka kiss Yamada again when he is in his own body. Her power turns out to be telepathy, and by incorporating Miyamura into their telepathic network they manage to pass the supplementary exams and obtain the key. They find that the storage room was cleaned out long ago and no trace of the second notebook is found. They try to figure out who had the room cleaned.

The student council has requested Yamada and Miyamura to visit a truant student named Sarushima. It turns out that she is another witch, with the ability to see the future, and stopped coming to school because she saw a vision of her causing a fire in the old school building. She kisses Yamada, who receives her powers, and they understand that the visions are from someone kissed. Yamada finds out that Sarushima earlier kissed another transfer student named Tsubaki. Yamada finds him, and learns that he has a crush on Shiraishi, and that he likes to fry tempura in the old school building whenever he is depressed. He is thus evidently the direct cause of the fire in the visions. To prevent the fire from happening, Yamada tries to swap bodies with Tsubaki, but he resists. He returns to Tsubaki in Shiraishi's body, bringing him out on a date in an attempt to stall for time, but before Tsubaki can confess his love, Shiraishi comes out and kisses him. This would have changed the future such that Shiraishi becomes blamed for the fire instead, but Yamada manages to stop Tsubaki from his cooking.

The student council has asked the Supernatural Research Club to investigate incidents of first-year students embroiled in trouble, which they believe to be caused by yet another witch, Takigawa Noa, who seems to have the power to see the past of those she kisses. Yamada has difficulty reaching her at first, but she perks up immediately when the topic of the witches comes up, which makes him very suspicious. As it seems that the powers of the witches are inherited by students who are troubled in some way, Takigawa's plan seems to be to make her friends obtain these powers by making them similarly troubled and removing the present set of witches. Takigawa's group attempts to get Shiraishi expelled by using her body swap powers against her and causing trouble while in her body, but the Club is one step ahead. Takigawa's friend winds up swapping bodies with Yamada in Shiraishi's body, who overpowers her companions. After they negotiate with Takigawa to release her friends, Yamada confronts her and he finds her power is to see traumatic events in the past of a person she kisses. He learns that her friends were framed for the troubles they found themselves in, and were disgraced as a result. Ultimately he convinces her to stop with her plans as he promises to help them to regain their original status.

It is the school festival, and the Supernatural Research Club uses Sarushima's powers to make a fortune-telling booth. Sarushima tells Yamada that she doesn't like having her powers of prognostication as she wants to fall in love, and wonders if there is a way to remove a witch's powers. They learn of Tamaki Shinichi, who has the ability to steal a witch's powers. He already took the power of invisibility from the witch Asuka Mikoto. He bargains with Yamada, getting him to look into the future to see who will become next student council president, as he has sights on the position himself. The student council president says that he will appoint as his successor whoever is able to identify the seventh and final witch. Yamada kisses Sarushima again and sees a vision of the future where Tamaki becomes president after taking Sarushima's powers and he has Shiraishi as his secretary. This vision of Shiraishi as sad and lonely as she once had been disturbs Yamada so much that he begins the hunt for the mysterious Seventh Witch in earnest. Yamada confesses to Miyamura that he has fallen in love with and doesn't want to see her that way ever again.

Tamaki has been using his invisibility powers to attempt to spy on the Supernatural Research Club and learn what they know about the Seventh Witch, not realising that his powers don't work on Yamada, who deceives him into believing they aren't making any progress. Miyamura introduces the club to his sister, Leona, who dropped out of school, terrified of the Seventh Witch's powers to make people forget everything about the witches. Yamada later meets the Seventh Witch, Saionji Rika, whose powers seem not to require a kiss. He seems unaffected, and still seems to remember everything. He returns to the Supernatural Research Club and is shocked to find that Saionji's powers have instead affected everyone else, and because they knew him only from their work with the witches, they have all, including Shiraishi, forgotten about him. He teams up with Tamaki, who seems to be the only other person in school who seems to remember anything. Tamaki suggests a plan that requires Odagiri's charm powers, so Yamada convinces her to kiss him. As they do this, Shiraishi sees them, and she bursts into tears without understanding why.

Yamada tries to explain to Shiraishi what was going on but she cannot accept the explanation and refuses to kiss him. The next day he runs into Odagiri who now seems to remember everything: Yamada can undo Saionji's powers on the witches by kissing them. Saionji meets up with Yamada again, and tells him that the reason the Seventh Witch's name is kept secret is because if one can gather all the witches together any wish can be granted by performing a special ritual. Saionji's powers fail to affect Odagiri a second time, so Yamazaki tries to take more drastic measures. He has the student council issue a warning about a "kissing bandit" in the school, which makes Yamada's attempts at restoring the memories of the other witches harder. He offers Odagiri a deal, noting that she has truly fallen in love with Yamada herself, that he would make her wish come true if she hindered Yamada's plans. She refuses, knowing that she would never be able to compel Yamada's love that way, that he would always be looking at Shiraishi. He then sends out notices to all the witches to gather at a certain place and time: he is attempting to perform the wish-granting ritual. Yamada then has to perform the ritual himself before Yamazaki. Tamaki and Odagiri try to find Saionji and convince her to help, but she refuses, and hints that Yamazaki may be planning to perform the ceremony to eliminate Yamada altogether. Despite Yamazaki's efforts Yamada is able to get to Ootsuka, Sarushima, and Takigawa. He tries to reach Shiraishi and finds that Yamazaki has gotten to her first, and it is Asuka Mikoto in her body.

Yamada attempts to get Miyamura to help him see Shiraishi, who is trapped in Asuka's body and is prevented from coming to school. His sister Leona asks to see him, and she asks him to tell her his story. Yamada, Odagiri, and Tamaki later meet with Saionji, who tells them the side effects of her powers: no one but Yamazaki knows about her and she has been so lonely as a result. Yamada points out that now the three of them also know about her, and if she continues helping Yamazaki it will be back to just the two of them. She agrees to help on the condition that they bring Leona to school. She agrees to go, after telling them how she was part of the original Supernatural Research Club with Yamazaki. and how Saionji removed his memories, making him forget all about her. Yamada finally reaches Shiraishi who is in Asuka's body and brings her to school and returns her to her own body. Leona and Yamazaki meet again, and he finds that though he doesn't remember her, his feelings for her were not erased. They perform the ritual, and Yamada wishes that the witch powers vanish from the school, knowing how these powers have all largely brought the witches sadness. In a private moment, Yamada finally gets to confess his love for Shiraishi, and the two of them kiss. They don't swap bodies any more.
