In 2007 a light novel was published in Japan based on the movie L: change the WorLd, which was itself a Spin-Off of the popular Death Note franchise. The novel in itself is pretty short, with only a total of 188 pages.
It's an alternative continuity to both the main Death Note series and the film it was based on. The story centers around L and his last 23 days on earth and twenty-two days to save the world from a terrorist group called Blue Ship whose main goal is to purify the world by killing off most of humanity with a deadly virus.
- Alternative Continuity: Basically it is a continuity similar to the manga, but with the alternate ending of "The Last Name" film.
- Big Brother Instinct: L to Maki. See Papa Wolf below.
- Bond Villain Stupidity: Both K and Matoba
- Children Raise You
- Eco-Terrorist: Has the most extreme version, with a group called Blue Ship who want to kill off most of humanity with a supervirus in order to save the environment.
- Foregone Conclusion: L will die in the very end.
- Gambit Pileup: At one time, there are at least four people with different agendas, with L, Blueship, Surega, Kujo, Maki, etc.
- Gambit Roulette: Misa accidentally writing the wrong date for Rod Ross's death and L using this to his advantage.
- Like Brother and Sister: The novel stated that L and Maki's close friendship is not just any type of friendship; they are like siblings.
- Mythology Gag: There are a few references to the original work and the movie:
- L revisits the Yellow Box Warehouse, where he meets Blue Ship for the first time.
- Rod Ross gets a passing reference, whose name is written down by L himself. However, considering that Rod Ross isn't his real name according to the manual, a reader might actually figure out that L didn't really kill him.
- Matsuda does the fake falling death he did in the Yotsuba Arc in a similar way, except in a gambit where he is pretending to be Surega, Surega posing as L, and with a fake Death Note.
- L hides things inside potato chip bags and even lampshades "Nobody would think that anything important would be inside a bag of potato chips" when Maki comments on it. He also mentions that he doesn't eat Consumme flavor chips.
- Papa Wolf: Played straight with L.
- When Maki went missing and got kidnapped, L went into full blown Papa Wolf mode and is ready to kick some Blue Ship ass.
- Towards the end of the novel L addressed to the president that if he doesn't promise to make a better world for the children technically "he" will not hesitate to use the Death Note.
- And L for the first time completely loses his composure and calm attitude: when Maki is kidnapped by Blue Ship, L breaks down and screams toward the sky .
- Pet the Dog: Misa genuinely cares for Maki like a sister.
- Ship Tease: L is (more or less) ship teased with both Light and Misa. Much to the delight of the shippers....
- Stalker with a Crush: L to Misa. His fanboy crush is pretty cute at first but then it slowly starts to get creepy.
- The Ditz: Subverted. When Kujo first meets Surega, she acts like she didn't know about the FBI. Zig-Zagged when it is revealed that Kujo is K.
- The Man Behind the Man: Kujo hijacks Mosuba's plan.
- The War on Straw: No, this is not the argument of the Green movement... Nor is this why anyone supported Kira.
- Well-Intentioned Extremist: Blue Ship's goal is to kill off most of humanity in order to save the environment. Kujo takes advantage of this.
