Literature: Koizora

Koizora: A Sad Love Story, or known as Koizora for short, is a cell phone novel written by Mika and published in 2005 on the website Maho no iLand. The novel received a print publication in 2006 and was split into two volumes. During its serialization, Koizora amassed widespread popularity and was considered a cultural phenomenon in Japan, as approximately 20 million people subscribed to the story and over two million copies of the book was sold.

Part of the reason to its popularity is because of Word of God claims it's biographical, and her anonymity makes the events of the story believable. This has been Retconned as being Very Loosely Based on a True Story, though there are rumors going on that it's Based on a Great Big Lie due its exaggerations and suspiciously strategic emotional appeal. Nevertheless, the success of Koizora led to a manga adaptation drawn by Ibuki Haneda, a theatrical film starring Yui Aragaki and Haruma Miura, and a television drama starring Erena Mizusawa and Koji Seto.

The story follows young Na´ve Everygirl Mika Tahara, a girl who daydreams of love. Through a random encounter of phone calls, she meets Hiroki "Hiro" Sakurai, a delinquent boy who she is initially afraid of, and the two gradually fall in love. Do they live Happily Ever After? ... Not exactly, when challenges in their lives pop up and threaten to split the couple apart, including a sociopathic ex-girlfriend, an unplanned pregnancy, and the possibility of death. There's a lot of Tear Jerker moments, so get your tissue boxes ready.


This series contains examples of:

  • All Girls Want Bad Boys: Invoked by the fact that Hiro's pretty much a delinquent, but he's really a Nice Guy.
  • Bastard Boyfriend: Hiro becomes this in the second part of the story.
  • Betty and Veronica: Tatsuya and Yu are the Betty and Hiro is the Veronica to Mika's Archie.
  • Berserk Button: Don't try to hurt Mika or else you'll face Hiro's bout of Unstoppable Rage.
  • Bittersweet Ending: Hiro dies during a routine check-up before Mika can say goodbye and Mika almost commits suicide, but after reading a posthumous letter from him she decides to live on for him, their late daughter, and to Mika's surprise, their new baby girl.
  • Bowdlerise: The original novel was darker than the film adaptation. Of note is Hiro's abusive Bastard Boyfriend tendencies in the second part, where Mika is literally put in danger when he tries to get her to break up with him. (Inhaling chloroform, anyone? Pressing a cigarette to your arm?)
  • Break the Cutie: The series really does push how much pain Mika has to go through.
  • Clingy Jealous Girl: Saki, Hiro's ex-girlfriend. This doesn't even begin to cover her. Hiring a bunch of guys to gangrape the girlfriend of the girl who recently dumped you, spreading rumors and becoming the direct cause of her bullying, pushing said new girlfriend down the stairs because she's pregnant with your ex-boyfriend's child...and the fact that she does all of this and virtually gets away with it.
  • Compressed Adaptation: The film can generally be seen as this for the novel, as many of the characters like Tatsuya, Uta, etc. in the original story were left out due to time constraints.
  • Cool Big Sis: Minako, Hiro's older sister.
  • Delinquent Hair: Oh, so very much.
  • Dogged Nice Guy: Yu becomes one for Mika.
  • Driven to Suicide: Mika attempts this several times, first time being right after she gets gang-raped. It doesn't make it any better when Hiro dies of cancer.
  • Go Out with a Smile: Hiro.
  • Good Girls Avoid Abortion: Played straight with Mika. Subverted with Uta, who genuinely is a good girl but was forced by her boyfriend to get an abortion not once, but twice. Inverted with Saki, who was a jerk to Mika but keeps her baby when she gets pregnant.
  • Harassing Phone Call: Saki sends a lot of these to Mika when she tries to do a Relationship Sabotage.
  • He Didn't Make It: Hiro and Mika's baby, later Hiro himself.
  • Huge Guy, Tiny Girl: Played straight with Yu and Mika.
  • I Want My Beloved to Be Happy: Hiro intentionally becomes a Bastard Boyfriend to convince Mika to break up with him, as he knows his days are numbered. Later, Yu heartbreakingly does this when he lets Mika return to a dying Hiro.
  • Ill Boy: Hiro is afflicted with cancer.
  • Jerkass Fašade: Hiro in the second part of the story to distance himself from Mika.
  • Kansai Regional Accent: Yu speaks with one.
  • Love Dodecahedron: It's a little confusing, since everyone's feelings change in the course of the story. Hiro and Mika obviously like each other. Saki likes Hiro. Aya and Nozomu date for a while until Nozomu develops a crush on Mika. Yu and Tatsuya also like Mika.
  • Love Makes You Evil: Love Hungry Saki tries to pull a Relationship Sabotage on Hiro and Mika's relationship when they start going out.
  • Mood Whiplash: Did you think it was going to be a light-hearted love story? Wait until you see what happens after Hiro and Mika get together.
  • Murder the Hypotenuse: It might be unintentional, but Saki attempts this when she pushes Mika down the stairs. Mika survives, but her baby doesn't.
  • Only Known by Their Nickname: Hiro is rarely called by his full name, Hiroki.
  • Pet the Dog: Hiro gets such a moment in the final part of the story, where the audience realizes that he's dying of cancer.
  • Poor Communication Kills: Had Hiro explained to Mika that he had cancer, We Could Have Avoided This Plot.
  • The Power of Love: How did Hiro find Mika after she gets gang-raped? "The Power of Love!"
  • Race for Your Love: Mika makes one to Hiro near the end of the novel, only to find out halfway that He Didn't Make It.
  • Rape as Drama: Mika gets raped by a group of men hired by Saki. This event alone causes Mika to have a Heroic BSOD and Hiro helps her through it.
  • Role Reprisal: Following the film, Haru reprised her role as Saki in the television drama.
  • Second Act Break Up: Halfway into the story, Hiro breaks up with Mika after learning he has cancer and resolves to keep his condition a secret so she won't have to suffer.
