“Waiting in the Summer” “Ano Natsu de Matteru.” (あの夏で待ってる。)

Despite the combined efforts of Tetsurō, Mio, Kanna, Remon (and the van-turned-robot and support from the Men in Black), and even Rinon (with a weapon provided by Emika); and even after seeing the desired location, which Kaito is able to see due to the nanomachines he got from Ichika, the proof they were looking for—a love umbrella carved into a tree by the alien who crash-landed on the place a long time ago—is gone, and the Federation recovery team takes Ichika away. But as a result of such encounter, the memories of the aliens about the distant time when they did arrive at the place were unlocked and become part of the memory for all those involved. As the new school term enters, Kaito’s sister Nanami returns from her trip to Bolivia with a gift for Ichika (a traditional incan vest); Kaito tells her that Ichika’s term abroad ended and she went back home. Remon, prior to transferring back to the MIB, leaves Kaito and the others an incomplete version of the film they have made. A few years later, Kaito, Mio, Tetsurō, and Kanna have graduated, but not without completing the unfinished film. During a re-showing at the school festival, Ichika (wearing Nanami’s gift) is seen appearing in it.

“Don’t Leave, Senpai” “Ikanaide, Senpai.” (行かないで、先輩。)

Emika is retrieving Ichika because the latter is on a planet where contact with its lifeforms is forbidden under their Federation laws, and the only solution is for her to leave this planet before things get messier. Ichika reluctantly agrees, but changes her mind when Kanna and the others arrive to stop her. Learning certain information from Emika, Remon tells them that Ichika may stay if the earthly spot Ichika has seen in her imagination is found in order to prove a probable previous contact between aliens and human beings. As the group finds the place, the search team arrives and starts a pursuit. Since Rinon’s teleport function becomes disabled, Remon takes the others to the spot using a van specially prepared with Emika’s help; with Tetsurō, Mio, and Kanna becoming bio-signature decoys for the pursuing rescue craft. However, a few kilometers from the site, the van collides with a cloaked drone from the rescue craft and overturns.

“Senpai’s and ours” “Senpai to Bokura no.” (先輩と僕らの。)

As Ichika and Kaito spend some time close together (which Ichika credits to Kanna), a depressed Kanna shuts herself in her room after a visit from Tetsurō, who tells everyone that she has a cold. He meets Mio on the way, where they shared the cake she was to give Kanna. There Mio asks and hears his reason why he invited Ichika to do the film with them. Angry at himself, Tetsurō kicks a nearby wooden railing and injures himself. The next day Tetsurō invites Kanna to their old playground as kindergarten kids and confesses to her, but she rejects him; and as she runs off to Kaito’s place to confess (only to be rejected by Kaito anyway), Tetsurō falls on his knees, where Mio sneaks from behind and hugs him, saying it’s alright to cry. The filming of the movie continues, but one day Emika, Ichika’s older sister, appears.

“Senpai” “Senpai” (せんぱい)

After the incident involving the rescue drone Ichika reveals her true identity to Kaito and the gang, and reveals her true intentions on Earth, namely “looking for that place in her memory.” Kaito, however, isn’t surprised because he already knows the fact. However, with the rather rough “rescue attempt” by the Federation rescue drone, she believes that another will come to investigate, and fears that her days on Earth are numbered; thus shunning Kaito for a while—and sealing her feelings for him. This irritated Kanna, telling Ichika that “looking for that place” is just an excuse to avoid him. Kanna confessed that she has feelings for Kaito, and runs away after confronting Ichika—only to be consoled later by Tetsurō, hurting Mio in the process. Kaito, with a bit of encouragement from Remon, did confess to Ichika later—and, when Kaito said it’s his first kiss, she revealed that she has kissed Kaito four times already, as she gave him the fifth one.

“Senpai in Trouble” “Senpai ga Pinch,” (先輩がPinch,)

After Ichika enjoys her first Japanese festival, Remon pops out of nowhere to challenge everyone to a test of courage at a dark shrine. During the test Rinon appears to Ichika, telling that an emergency beacon has been activated. True enough, a Federation lifeboat (a rescue drone) comes to rescue her (it’s more of taking her by force), but Ichika refuses, saying she has still a lot to do. Then again, when Kaito hears Ichika scream, he rushed to where she is, abandoning his partner Kanna. Even with the help of Rinna, one of Ichika’s machines, Kaito dies rescuing “the one he loves.” Ichika, however, manages to reverse Kaito’s death. Kaito awakens and sees himself with Ichika inside a ball of light, and mysteriously returning to the same spot. Everyone catches up to the two and sees Ichika incessantly apologizing in front of Kaito.

“Senpai’s Feelings” “Senpai no Kimochi.” (先輩の気持ち。)

Ichika’s worries are banished when she gets to the root of what’s going on with Kaori and Kaito; while Mio does her best to protect Tetsurō from a ravenous Chiharu—to a point of revealing a secret. The group wrapped up their filming the next day, as Kaori and Chiharu leaves for the airport right after filming.

“Senpai’s Rival” “Senpai ni Raibaru.” (先輩にライバル。)

As Ichika is pondering on what Tetsurō told Kaito that night, thanks to Tetsurō’s sister, filming for their movie goes to Okinawa, where Kaito meets a childhood friend, and her companion is attracted to Tetsurō. This puts Kanna and Ichika at an unease, especially when Kaori, the girl, says that Kaito is her fiance. Mio, on the other hand, is uneasy herself when Chiharu, Kaori’s companion, sets her sights on Tetsurō.

“Senpai Is a Heroine” “Senpai wa Hiroin.” (先輩はヒロイン。)

Ichika becomes the heroine of the independent film the gang were planning before summer break. Kaito agrees, while helping Ichika look for that particular place she is looking for. Kanna becomes uneasy when the lines for the film becomes somewhat uncannily realistic, especially in the scenes involving Kaito and Ichika. Even Kaito was surprised by Ichika’s questions that evening. As the next day was a rainy one and filming is cancelled, Kanna goes to Kaito’s house to bring some nozawana. That evening, Tetsurō, after meeting an uneasy home-bound Kanna, sneaks into Kaito’s room. He tells him that she, his childhood friend, is in love with him. Ichika overhears the conversation.

“Senpai Was Amazing” “Senpai wa Sugokatta.” (先輩はすごかった。)

Things turn awkward the next day, but they try to put it behind them. More complications arrive when Manami, Tetsurō’s married sister, takes Kaito shopping. Ichika sees them, and follows them via teleportation with Rinon’s help, even to Manami’s apartment. Worried about what will happen next, Ichika enters and tries to take him home, though not without clashing a bit with Manami. Tetsurō arrives and clears things up, telling Ichika that Manami is already married, and she is here because of a petty quarrel with her husband. As an apology, Ichika asked Kaito if she could do anything for him. He asked if she could help him review for the finals, to which she agreed, and helped him study until the final day of exams.

“Senpai Says…” “Senpai ga Icchau…” (先輩が言っちゃう…)

Kaito seems to be frustrated with his failed attempt to confess to Ichika, so he decides to ditch school, telling her to leave him alone for a while. Worried, Kanna goes to visit him at his house. Her visit turned into a date as the two went to Karuizawa. Ichika sees them from a distance and follows them. Kanna had to leave Kaito when she finds out Remon has been filming their “date.” It so happened that Ichika crosses paths with Kaito. Nervous of the prospect that she wants to talk to him, he runs away from her, and a chase ensues. It was all about a misunderstanding—that Kaito wants to know Ichika’s secret, while Ichika wants to know who dumped Kaito. When Kaito took some footage of Ichika, it turned out into some sort of an informal confession. Shocked, Kaito stops filming her.

“Together with Senpai…” “Senpai to Issho…” (先輩といっしょ…)

In this episode Ichika is revealed to be an alien journeying to look for a certain scenery that she has been seeing in her imagination. She crash lands on Earth when her spacecraft hits space debris. Meanwhile, Nanami awakens, saying she has had a dream about Kaito being hugged by a naked girl in a ball of light. Nanami gets to know Ichika, and out of nervousness the latter almost reveals that she is an alien, but manages to convince them that she is a foreign student. Listening to her story, Nanami lets her move in with them, since she will be away for quite some time, and she was looking for someone to take care of Kaito. Kanna was surprised to hear it, even thinking it to be some sort of a wedding arrangement in exasperation. After seeing Nanami off the next day, and right after shopping for clothes for Ichika, Kaito finds Remon, Tetsurō, Mio and Kanna inside the house—to talk about the movie project. After Remon served them some sort of spiked alcoholic drink, which had “bad” effects on Kanna, Kaito again fainted due to the same illness, but Ichika kissed it away.

“I Can’t, Senpai” “Komarimasu, Senpai.” (困ります、先輩。)

While testing his high-speed film video camera, first year high school student Kaito Kirishima sees a bright blue light, then an impact has blown him off of his footing and beyond the railings. He sees a hand grabbing his as he fell, bloodied, only to wake up in his futon the next day. At his school, a transfer student named Ichika Takatsuki comes to a third year class. Somehow the both of them has a familiarity with each other when his classmate Tetsurō approaches her and her classmate Remon Yamano, proposing that she joins a movie project he and Kaito are planning. She accepts it without hesitation, and Remon volunteers to write the script. Kaito’s classmates Kanna Tanigawa and Mio Kitahara volunteered later. When Kaito goes to test his camera after class, he finds Ichika fishing in the river. He finds out that she has nowhere to go, so he unwittingly offered her to stay at his house, given that his sister will be away for three months. Back home, as Ichika takes a bath, Kaito felt pain in his neck, then sees a flashback of what happened the evening before. Ichika finds him unconscious, with a sign of increased metabolism on the area where that insect bite was. Ichika then calls for her assistant Rinon to stop it, as she kissed him. Exactly as Kanna and Kaito’s sister Nanami arrive.

“Plan!” “Keikaku!” (計画!)

Shortly before episode 14, after receiving souvenirs from Tsumugi’s trip to Finland following the summer festival, the girls decide to plan for an overseas trip after graduation. They practice various things for overseas travel, only to realize that, besides Tsumugi, none of them has a valid passport. While lining up to hand in their passport applications, Ritsu realizes she forgot her identity card so she sends her little brother Satoshi to fetch it. Mio needs to take a suitable photograph to complete her application, but keeps getting bothered by the others while attempting to take it. With everyone having their own ideas of where they would like to go, Yui suggests that they go on a second trip after Azusa graduates.

“Visit!” “Hōmon!” (訪問!)

Set before episode 23, Nodoka arrives in the clubroom with a sample of the graduation yearbook. The yearbook needs to be checked by Sawako, who is sick with a cold. Curious about what her apartment looks like, the girls decide to pay her a visit. While looking through the album, they find a mysterious hand in the group photo, which turns out to be Ritsu’s. Despite Sawako’s objection, the girls decide to help her out around the apartment. They briefly visit Azusa, who is busy rehearsing for her freshman reception with Ui and Jun.

“Planning Discussion!” “Kikaku Kaigi!” (企画会議!)

Set just after episode 21, Azusa finds the light music club’s attempted recruitment video from before she joined the club, which was so embarrassing that Mio hid it in a cookie can. In order to recruit some new members for the next year, the girls try to come up with pitches for a new recruitment video, but to no avail. After talking with Ui and Jun, Azusa comes up with the idea of filming a documentary of their activities, intersected with interviews from fellow students and staff. The video turns out great, besides one scene at the end which Azusa is not too keen on.

“Graduation Ceremony!” “Sotsugyōshiki!” (卒業式!)

On the day of the graduation ceremony, Yui gets off to a rough start by being late and ripping her tights. Meanwhile, Azusa is similarly distracted and ends up banging her head. The girls hold on to a card signed by the entire class, though Yui’s attempts to hide it during the graduation ceremony cause Sawako to grow suspicious. They later give Sawako the present as thanks for being their teacher. After the classroom empties, leaving behind several goodbye messages on a chalkboard for Sawako, the girls go to the light music club room, shortly followed by Azusa. However, Azusa, who had been holding in her feelings all day, finally breaks down into tears, begging them not to graduate. To cheer her up, the girls perform a special song that they wrote just for her.

“After School!” “Hōkago!” (放課後!)

Although they are not supposed to be at school until graduation the next day, Yui and the others decide to hang around the club room, though they have trouble figuring out how to pass the time. They clear out their desks and visit the student council room before getting Azusa to buy them some lunch. Wanting to leave something behind after they graduate, the girls decide to record an album of their songs.

“Entrance Exams!” “Juken!” (受験!)

As the seniors prepare for their entrance exams, Azusa decides to make them a chocolate cake for Valentine’s Day, getting Ui and Jun to help. When the day comes, Azusa becomes nervous about presenting the cake to them and is also worried about their impending graduation. However, her friends encourage her and the cake is well received, even getting a speedy White Day gift from Yui. The next day, Azusa makes an expensive prayer at the shrine for the girls’ success, and later receives word that they have all passed their entrance exams.

“Graduation Yearbook!” “Sotsugyō Arubamu!” (卒業アルバム!)

With photos for the graduation yearbook coming up, Yui uses Ui as a model to determine the best hairstyle, though feels weird when she leaves her hairpin on her. Although the seniors have finished their clubs, the girls decide to use the light music club room to study for their entrance exams, though Yui and Ritsu have yet to decide on their university choices. While trying to trim her bangs for her yearbook photo, Yui sneezes and accidentally cuts them off, giving her a completely different look. After their pictures are taken, the girls learn Mio had turned down a recommendation for a university because she wanted to study together with everyone. Upon hearing this, Yui, Ritsu and Mio turn in their university preference applications to Sawako, opting to go to the same women’s university as Tsumugi.

“Yet Another School Festival!” “Mata Mata Gakuensai!” (またまた学園祭!)

The girls get on stage for their performance and are surprised to find everyone in the audience wearing the same shirts as they are, which moves Yui a lot. During their performance, they sing two new songs, and Yui gives her thanks to the people who have helped her, and even gets thanks in return from the others. After their performance, the girls look back on their previous years and start to become upset knowing that this is their last year together, but manage to cheer each other up.
