Love, Chunibyo & Other Delusions! Take on Me

After the events of the series, Yūta Togashi, Rikka Takanashi, and Shinka Nibutani are now on their third year of high school. Their junior, Sanae Dekomori, is now the president of the student council. Rikka's sister, Tōka, tells Yūta on a call from Italy that she wanted to bring Rikka to Italy as her career stabilizes. Yūta and Rikka initially assume that it was meant only to last the whole spring break; however, they soon found out that Tōka intends to permanently bring Rikka to Italy. That night, Shinka and Sanae, along with their friend Satone Shichimiya and senior Kumin Tsuyuri, suggest that the two elope. The two agreed, and they board the train the following morning.

Tōka soon discovers the plan, and she comfronts the remaining members who insisted that they knew nothing. After revealing that she had secretly recorded their conversation last night, she blackmails the group. Afraid of losing reputation at school, they complied.

Shinka and Sanae eventually found Rikka and Yūta at the Kyoto Tower, but the two managed to board a train to Kobe. Tōka comfronts Yūta while eating. After asking questions about Rikka's chūnibyō, Tōka let the two leave, warning that she would detain them if they happen to cross paths next time.

Rikka and Yūta arrive at Wakayama, where they attempt to book a room at a love hotel. They eventually failed, and as they leave, they saw Sanae and Shinka. Yūta deduces that Tōka is tracking them using Rikka's phone. They arrive at Tokyo for sightseeing. Unknown to Rikka, Yūta buys a butterfly-shaped ring. Running low on cash, they decide to go to Hokkaido to visit Rikka's mother. However, the two don't know the contact details, so they try to retrieve it on a basement so that Tōka couldn't use the signal to track them. However, the phone managed to transmit a faint signal, enough to reveal their location to Rikka's sister.

The next day, they went to Haneda Airport, where they saw Shinka and Sanae. After creating a distraction for the two, they successfully boarded a flight to Hokkaido.

Arriving at Hokkaido, Yūta reveals his intention why he wanted to talk to Rikka's mother about Rikka's future. The couple soon found out that Rikka's mother is not home, and instead at Aomori. Meanwhile, Rikka calls Satone back home about her "losing powers."

The next day, Yūta discovers that she lost Rikka. However, he soon learned from Rikka's mother that Rikka had already meet up with her that morning.

Rikka is revealed to went on the seaside, struggling about her conflicting feelings. Satone and Kumin arrive at the scene, convincing Rikka to go back to Yūta. Rikka confesses her thoughts to them, telling that if she changes, she might lose Yūta. Sanae and Shinka arrive at the scene later, telling the group that they had informed Yūta about Rikka's whereabouts. As a sign of truce, Shinka gives them tickets for a cruise. The couple reunite with a huge embrace.

At the cruise that night, Rikka asks Yūta about her "abandoning her powers" and if Yūta still love her even after that. Yūta reaffirms his love for her, leading to their first kiss.

Rikka and Yūta, along with the group, still went to Italy, where Tōka reveals that she is marrying an Italian man and that the whole pursuit was a ruse to test Yūta's determination.

On the post-credit scene, the group went back home. Rikka's new apartment is now two floors above Yūta's. As Rikka climbs down on a rope to meet him, Yūta realizes that everything about her is the reason why he fell in love with her in the first place.

Kim Morrissy of Anime News Network praised the film for finally progressing Rikka and Yuta's relationship, but otherwise felt that it somewhat retread ground covered by the first two television series. He also found the film's animation to be good but lacking, more in line with the TV series than a typical theatrical production, and made special note of the poor inclusion of 3D objects, such as vehicles, into the 2D animation. He appreciated the film's many references to other Kyoto Animation series, such as Tamako Market, Sound! Euphonium, The Melancholy of Haruhi Suzumiya, and Clannad, and opined that the film would mainly appeal to fans of the series who had enjoyed the second season of the anime, as well as fans of Kyoto Animation's other works.[14]
