Rumbling Hearts

Short version? Guy dates girl. Girl gets in a car accident and is left in a coma. Girl's best friend eventually gets guy to get over his misery and starts going out with him herself. Girl finally wakes up from coma. Drama ensues.

Longer version? The highschooler Takayuki Narumi has just begun going out with his classmate Haruka Suzumiya; this is supported by Haruka's best friend Mitsuki Hayase, despite her secret feelings for Takayuki himself. However, the happiness is cut short when Haruka is hit by a car and falls into a coma, which destroys poor Takayuki on the inside and causes him to develop PTSD; Mitsuki, who blames herself from all fo this, decides to more or less drop her swimming career to take care of him.

Three years later, things are somewhat more stable — and Mitsuki and Takayuki are lovers. Then, Haruka wakes from said coma and her treating doctor says that she has amnesia as a consequence, and recovering her memories could actually kill her out of shock. So everyone must build a charade where time has not really passed for the sake of Haruka's mental stability, but it has quite the consequences on all of them. . .

Kimi ga Nozomu Eien (君が望む永遠, lit. "The Eternity You Desire"), or Kiminozo for short, known is a Japanese adult visual novel developed by Âge and released on August 3, 2001 for Windows. It was later ported to the Dreamcast and PlayStation 2. Still, outside Japan it's much better known by its Animated Adaptation Rumbling Hearts, a 14-episode TV series that aired in 2003-2004, and which follows mostly Mitsuki's route with some touches of Haruka's and Akane (Haruka's younger sister)'s paths. It also had a 4-episode OAV from 2007-2008, based on Haruka's route.

In 2019, a reboot of the original VN was announced.

Has a sequel of sorts in the form of the Muv-Luv series.

Tropes used in Rumbling Hearts include:

• Anime Hair: DAMN that is some crazy hair, Mitsuki. She cut it short later though.
• The Anime of the Game: Originally based off of an H-Game.
• Angst Coma: When Haruka actually finds out about the three years from Akane, she spends a short while in one of these.
• Arc Words: Three years.
• Bittersweet Ending: (Mitsuki's route, which was followed by the TV adaptation): In the end, Haruka decides she can't be with Takayuki because he's not the same person he was three years ago; Takayuki finds Mitsuki and convinces her not to leave, and says he won't see Haruka again. It then skips to the first children's book Haruka wrote, about a character who just wants to get to the top of a hill to see her friends once more. The last shot is of Haruka standing in front of the tree, hopefully waiting.
  • And even when they're together, Takayuki has foregone his chance for a better full-time job, while Mitsuki not only couldn't get back to her swimming career she abandoned long ago, she also lost her Office Lady job. But at least they're together.
• Break the Cutie
• Broken Pedestal: Mitsuki becomes this to Akane, when she catches Mitsuki naked in Takayuki's bedroom and finds out they're involved.
• Can't Catch Up: Haruka lost three years of her life, staying the same as her friends grew up.
• Catch Phrase: Ayu's "You can go step in cat crap!"
• Cute Little Fangs: Ayu, one of the waitresses in the restaurant Takayuki works at.
• Deconstructed Trope: True Companions, as Takayuki and Mitsuki's devotion to Haruka takes huge tolls on the three. Plus it shows that the bonds built in childhood / adolescence can be very strong, but also very fleeting and especially easy to change in the face of an event that changes EVERYTHING,
• Demoted to Extra: If you only see the anime, you wouldn't notice that some extras like the doctor or some of her assistants, and Mayu/Ayu can be love interests.
• Dude, She's Like, in a Coma: Takayuki to Haruka, only instead of kissing, he tries to take her on a date. While she's still comatose.
• Evolving Credits: The series doesn't have the normal opening until the third episode, when the main story takes place.
• Faux Yay: Takayuki on Shinji in episode 1. Shinji is less than amused.
• Genki Girl: Haruka's sister, Akane, before the accident.
• Gut Punch: Especially in the Visual Novel, but the anime also doesn't let up. Can't spell "rage" without "age", indeed.
• Half Truth: Everyone with respect to Haruka after she wakes up.
• Heroic BSOD: Takayuki, after the accident. He stays that way until Mitsuki finally snaps him out of it.
• I Coulda Been a Contender: Mitsuki Hayase, a once-in-a-generation swimming prodigy, has the makings of an Olympic-Grade Champion. She leaves it behind to take care of her best friend Haruka's boyfriend Takayuki, so suicidally depressed over Haruka's car-accident induced coma (which Mitsuki blames herself for) that he could not finish high school.
• If You Ever Do Anything to Hurt Her...: Mitsuki says this to Takayuki regarding Haruka.
• Ill Girl: When Haruka wakes up, other consequences of her accident include her being barely able to walk on her own and catching fevers easily.
• Locked Out of the Loop: See Half Truth above.
  • Also Akane. Did her parents even bother to tell her that "Takayuki won't be seeing her anymore, since we told him to stop coming"? Nope, hence the incredibly painful to watch scene where Akane tells both of them off for not coming to visit (in the latter case, Mitsuki actually wanted to visit but was called a traitor by Akane herself).
• Look Both Ways: Inverted: Haruka was waiting for Takayuki in a safe spot (a telephone booth), then the car rammed into her for whatever reason.
• Love Triangle: Between the newly awakened Haruka, Mitsuki, and Takayuki.
• Market-Based Title: The better-known title, Rumbling Hearts, is the official one for the North American release of the anime, and also the title of the opening theme for the original visual novel. The Japanese name for the series is Kimi ga Nozomu Eien (The Eternity You Desire), shortened as KimiNozo.
• Matchmaker Crush: Mitsuki, on Takayuki.
• Mood Whiplash: The anime may be really sad and such... but the Omake in the end? REALLY lighthearted in comparison.
• Names to Know in Anime: Kissho Taniyama as Takayuki and Chiaki Takahashi as Mitsuki (although Chiaking used the pseudonym 'Tomoko Ishibashi' here)
  • And there's also Kaori Mizuhashi (better known this day as Mami Tomoe) as Akane.
  • Haruka is voiced by the Idol Singer Minami Kuribayashi.
• Omake: Instead of a next episode preview, there's an omake at the end of each episode.
• One Side of the Story: Akane, when she walks in on Mitsuki in Takayuki's bed — without knowing that her parents had just told him to gtfo, or that Mitsuki offering herself to him might have been the only thing that kept him from going off the deep end forever.
  • This is an endless source of Dramatic Irony, since Akane is always out of the loop, making some scenes with Akane just painful.
• Plot Induced Stupidity: Both straight and justified. A doctor treating TBI (Traumatic Brain Injury) by demanding that everyone play along with a false reality? It speaks volumes that the same doctor frequently smokes in the hospital... near oxygen. On the other hand, there are several points of the story where characters do unbelievably stupid things. . . that are completely consistent with their individual pathologies.
• Poor Communication Kills: Haruka's parents and the doctor might have had second thoughts about what they were asking of Takayuki if they knew about his relationship with Mitsuki.
• Running Gag: Haruka getting involved in a vehicle accident carries over to age's other works like Muv Luv Alternative and Ayu-Mayu Theater.
• Shown Their Work: The producers of the anime series did their research on PTSD as it applies to Takayuki, and it shows.
• The Cameo/Marth Debuted in Smash Bros: The adaptation has the first animated appearances of Yayoi Isumi (Takayuki's landlady, originally from age's debut title Kimi Ga Ita Kisetsu) and Chizuru Sakaki (Akane's rival and best friend, originally from the quasi-sequel Muv-Luv).
• The Klutz: Mayu. She even has band-aids all over her face. Which begs the question, why didn't she have one handy when Takayuki cut his finger in the anime?
• Theme Tune Cameo: Mitsuki hums the opening at the beginning of Episode 8.
• Those Two Guys: Ayu and Mayu, the two waitresses who Takayuki works with at the Sky Temple family restaurant.
• Time Skip: Haruka is in a coma for many years after the car crash. Drama ensues.
• Tomboyish Ponytail: Mitsuki is a sporty, more tomboyish girl compared to Haruka, so she gets the ponytail. She cuts it in the end though.
• Unwitting Instigator of Doom: A part of Mitsuki's attitude can be explained by her considering herself as one. Haruka and Takayuki's fateful date took place in her birthday, so she asked him to buy her a ring as a present before the meeting. He was late for the date — and as Haruka waited for him, she was hit by the car and left comatose, which caused poor Takayuki to mentally collapse out of guilt. Unsurprisingly AND understandably, Mitsuki heavily blames herself for everything,
• Utsuge
• Who Wants to Live Forever?: Referenced in Mayal's Gift in the final episode.
• Writer on Board: The doctor's plan to help Haruka by having everyone pretend no time has elapsed might have passed for simple Did Not Do the Research... if they hadn't done such a painfully-accurate portrayal of the effects of PTSD.
