Ano Natsu de Matteru(2012)

1 - I Can't, Senpai

While testing his high-speed film video camera, second 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 Lemon Yamano, proposing that she joins a movie project he and Kaito are planning. She accepts it without hesitation, and Lemon volunteers to write the script. Kaitos 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.

2 - Together With Senpai...

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 Lemon, Tetsurō, Mio and Kanna inside the house--to talk about the movie project.

3 - Senpai Says...

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 awhile. Worried, Kanna goes to visit him at his house. It turned out 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 Lemon 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 Ichikas 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.

4 - Senpai Was Amazing

Things turn awkward the next day, but they try to put it behind them. More complications arrive when Manami, Tetsurōs married sister, takes a homebound Kaito for shopping. Ichika sees them, and followed them via teleportation with Rinons help, even at her place. Worried about what will happen next, Ichika enters and tries to take him home...though not without clashing a bit with Manami, acting like an overprotective lover, until Tetsurō comes to clear things up, that Manami is already married, and shes here because of a petty quarrel with her husband. As an apology Ichika asked Kaito for a favor from 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.

5 - Senpai Is the Heroine

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 Ichikas questions that evening. As the next day was a rainy one and filming is cancelled, Kanna goes to Kaitos house to bring some nozawana. That evening, Tetsurō, after meeting an uneasy home-bound Kanna, sneaks into Kaitos room, and tells him that she, his childhood friend, is in love with him. Ichika overhears the conversation.

6 - Senpai Has a Rival

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

7 - Senpai's Feelings

Ichikas worries are banished when she gets to the root of whats going on with Kaori and Kaito; while Miu 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.

8 - Senpai's Pinch

After Ichika enjoys her first Japanese festival, Lemon 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 League lifeboat (a rescue drone) comes to rescue her (its more of taking her by force), but Ichika says 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 Ichikas machines, Kaito dies rescuing the one he loves. Ichika, however, manages to reverse Kaitos 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.

9 - Senpai

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, isnt surprised because he already knows the fact. However, with the rather rough rescue attempt by The League rescue drone, she believes that another will come to investigate, and fears that her days on Earth are numbered; thus shunning Kaito for awhile--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 Lemon, did confess to Ichika later--and, when Kaito said its his first kiss, she revealed that she has kissed Kaito four times already, as she gave him the fifth one.

10 - Senpai and Our...

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 Kaitos place to confess (only to be rejected by Kaito anyway), Tetsurō falls on his knees, where Mio sneaks from behind and hugs him, saying its alright to cry. The filming of the movie continues, but one day Emika, Ichikas older sister, appears.

11 - Don't Go, Senpai

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 Rinons teleport function becomes disabled, Remon takes the others to the spot using a van specially prepared with Emikas help; with Tetsuro, Mio, and Kanna becoming bio-signature decoys for the pursuing rescue craft. However, a few kilometers from the site, the rescue craft overturns the van.

12 - Waiting There, in the Summer

Some unexpected allies have joined the cause to help Ichika and Kaito, and they pack firepower. But if Ichika and Kaito make it to the spot in her dreams, what will they do then?
