Monster by amour tue lentement is a Death Note AU and Dark Light/L Slash Fic. Ryuuzaki, the police secretary and errand boy, suddenly finds himself pursued by unknown enemies and haunted by a past he can't remember.
Monster provides examples of:
- Antagonist in Mourning: After Misa kills L, Light rubs out the name so hard with the death eraser that it bores a hole in the page.
- Axe-Crazy: This version of Light Yagami flips out and becomes physically violent at the drop of a hat.
- Awful Truth: To his horror, L learns that before he lost his memories he was Kira's accomplice and lover. Though it's slowly revealed that it's slightly more complicated than that...
- Back from the Dead: The reason why there are gaps in L's memories is because Misa KILLED him in a jealous rage. Light brought L back with a Death Eraser he received from Ryuk.
- Carved Mark: When Light kidnaps L again he carves an "L" into his hip. L muses it's a "two percent chance that the L was for Lawliet, and a ninety-eight percent chance it was for "Light's"."
- Contrived Coincidence: Light rediscovers L because Aizawa just happened to drive by where Light (a wanted fugitive who has been declared dead) happened to be out jogging.
- Donut Mess with a Cop: It becomes Ryuuzaki's job to get the dougnuts (and not eat them).
- Enigmatic Minion: Ryuk he sticks around Light despite being disgusted by him (even more so than in canon) and for some reason he gave Light the death eraser.
- Fetishized Abuser: Light is a toxic yandere toward L — emotionally dependant. jealous, and overall unhinged. Yet, he and his relationship with L are portrayed as cute.
- Identity Amnesia: As far as Ryuuzaki knows he's just the secretary and police errand boy.
- In Medias Res: The story begins with L having Identity Amnesia and a Dark and Troubled Past.
- It Amused Me: After L found Kira he didn't particularly care about such details as turning him in seeing as he was just solving the case for his own amusement and had become rather fond of Light. After learning this Light became rather insistent that L remain at his side.
- Patricide: In a moment of desperate panic Light killed his own mother.
- Mood-Swinger: Light is much more unstable here than he is in canon because he murdered his mother.
- Prompt Fic: L x Light generator challenge "The theme of this story: dark romance. The main characters: courageous secretary and infamous outlaw. The major event of the story: destruction."
- Reformed, but Rejected: The taskforce gives the amnesiac Ryuuzaki a hard time because they believe he betrayed them.
- Rhetorical Question Blunder: when L comments on Misa's enthusiasm for killing criminals Light asks:Light: Is it a crime that someone else is as committed to cleansing the world as I am?
L: Yes, actually, it is. That's called mass murder.
- Shout-Out: To Code Geass — because of his tactical genius Light gets the nickname Light Lamperouge and one of the names Mikami sees on a crowded street is Suzaku Kururugi.
- Wounded Gazelle Gambit: When Misa calls up the police she downplays her involvement, claiming that she was "so scared" of Kira...
- You, Get Me Coffee: after losing his memories "Ryuuzaki" becomes the office boy who gets coffee and doughnuts for Aizawa and Matsuda. Laser-Guided Karma?
- You Will Be Spared: Mello spares Aizawa in a Pet the Dog moment and Light spares L insisting that they can rule together and later brings him back to life with the death eraser after Misa killed L in a jealous rage.
