"Hearts Come Together" (心重ねる Kokoro kasaneru?) is the eighteenth episode of the Shigatsu wa Kimi no Uso anime adaptation. It first aired in Japan on February 19, 2015.


Kousei asks Nagi to let him perform at the Kurumigaoka Junior High culture festival. He wants to reach Kaori through his music. With that in mind, he and Nagi take the stage, and their performance begins. But unlike during practice, Kousei, the supporting player, in a complete switch of gears, begins playing at an incredible pace, filling the music with an aching atmosphere, pressuring Nagi. And Nagi, unwilling to give in to Kousei, tries to hold her own…


In a flashback, Nagi consults Kousei about why he wants to perform at her school's culture festival. Kousei replies with how he has a "horrible friend" who is feeling sorry for herself and how he wants to "punch her, just once", referring to Kaori and how she has lost sight of her dreams. Nagi monologues, feeling sure that something will change during their performance.

Kousei and Nagi enter the stage at the culture festival and approach the piano, with a variety of audience members, including Takeshi, exclaiming about Nagi's choice of support being Kousei Arima and questioning their relation. They begin their performance and Nagi monologues about how well they've started off and how she feels calmer now that she has begun performing.

Kousei monologues about how he cannot let himself concentrate else he'll stop being able to hear himself play. With this, he begins to play at a higher tempo, startling the audience and Nagi, causing her to panic and feel like she's being overpowered by him. This causes her to challenge Kousei in a monologue, telling him to "Bring it!" as she picks up her playing to compete with Kousei. This amazes the audience as their playing is in perfect harmony and both musicians are able to synchonise with each other and know what they will do next.

Nagi monologues about how the past two months of practice have paid off, and how Kousei is not the "Chogokin Robot" that her brother once described him as. She instead remembers the moments they have shared together; his warm hands, the sweet potatoes, their walks home. She recalls why she started playing the piano; an "ulterior motive" to regain her brother's attention, which she lost Kousei stopped playing the piano and Takeshi began to doubt his hero. Nagi then begins to play at an even faster tempo in an attempt to get him to notice her from the crowd and tell him to continue pursuing his hero.

At the hospital, Kaori, who can hear the performance on her phone via a phone call from Watari, begins to imitate playing the violin. Back at the festival, Takeshi begins to become frustrated at the fact that he isn't the one on the stage performing, and cannot understand why both Nagi's and Emi's recent performances have begun to move people's hearts, and then questions whether Kousei is the reason.

Nagi realises their performance is about to end and questions whether she played the piece with total sincerity. She asks herself why the notes that Kousei plays are so colourful and vibrant as they finish the song. At the hospital, Kaori stops imitating their performance and begins to cry.

Kousei prompts Nagi to stand up and take a bow before the audience, who are cheering them on. Nagi asks Kousei whether he thinks her playing reached "him", to which Kousei replies that he believes it did. Nagi also asks whether he managed to give his friend the punch he wanted, to which he also believes he managed to. Nagi offers her hand to Kousei, who holds it and takes a bow, much to the dismay of Takeshi.

Takeshi's friend questions whether he will take anything away from his sister's performance, emphasising how Nagi "climb the stairway", despite her brother complex and everything else bothering her. Takeshi cannot bring himself to answer the question.

Backstage, Nagi cheers in relief of the performance being over and is met by applause from her friends. Hiroko asks Kousei whether he finds it thrilling to watch someone grow, referring to Nagi. Nagi asks Hiroko how she thinks she did, to which she states that life has been interesting every day since both her and Kousei came along.

Takeshi appears backstage, grabbing the attention of Kousei who cannot remember his name. Takeshi begins shouting at him for being so close to his little sister, much to the confusion of Kousei, who thought Nagi's last name was "Aizato", not Aiza. Nagi refers to him as dense.

Takeshi begins to pester Kousei as to why he was performing with Nagi, and becomes angry when he refers to Nagi by her first name, stating that he should be referring to her as "Takeshi's little sister". Nagi defends Kousei, stating how he has helped and taught her recently, which Takeshi takes the wrong way and declares that he will beat Kousei at the Eastern Japan Piano Competition in December. Hiroko comments about how entry in that competition will be a pain, while Nagi monologues about whether her brother even slightly understood what she was trying to convey through her performance.

The next day, Nagi is confronted by Miike, who questions why she is so close to Kousei. She becomes annoyed when Miike does not refer to Kousei with honorific and starts bragging about having his phone number and email address, and about how they regularly eat lunch together.

Over at the hospital, Kaori is on the roof playing "Twinkle Twinkle Little Star" on a keyboard with two children. This is cut short by the appearance of Kousei, who the two children question Kaori about whether he is her boyfriend, to which she denies and states that he is "just a jackass". Kaori replays a recording of Kousei's performance and states how it was evil to make a violinist listen to it.

Kousei goes on to state that he cannot commit a "double suicide" with Kaori as he has always been behind her, whether it's carrying her bags while shopping or her always taking the initiative. He states that it wouldn't be a double suicide as he would only be following her. Kousei instead pleads for Kaori to perform a duet with him once again, to which she tries to deny it.

Kousei interrupts, stating that she's not a princess and that she's a regular person who should perform with him once again. He asks whether she'll forget their past performances, to which Kaori states light-heartedly that he really is cruel. Kousei smiles and states how he thought she already knew he was a jackass.

Kaori begins to monologue about her surroundings and how Kousei is cruel for making her dream about playing her violin once again. She begins to cry, which causes the children to start attacking Kousei and make her laugh. Kaori then reignites her dream to perform alongside Kousei once again sometime as the episode ends.
