Fan Fic / Zero vs Kira

"I am Kira, and I have come to answer the grievances of the people of Japan against the Britannian Empire. For seven years, Japan has been brutally oppressed to satisfy the greed, ambition, and imperialistic tendency of Britannia, but now I am putting an end to that oppression. The Britannian Empire must pull their forces out of Japan in 52 hours from now. If they do not, I will kill the Emperor and his children. And to demonstrate my power, I will take the lives of two of Britannia's agents of propaganda. They will die for spreading lies and misinformation for the sake of the occupation and to make it clear that even the Emperor is defenseless against my power."

Zero vs Kira by Crossover Maniac is a Code Geass and Death Note crossover where Light Yagami is teleported to the Code Geass world when a Britannian world-breaching experiment Goes Horribly Right. Furious that the Britannians tried to kill him and enslaved his country, Light introduces the power of Kira to the Code Geass world when he declares war on Britannia. Also seeing no immediate way of returning home, Light feels he may as well create the New World he envisions here. Meanwhile, Kira's activities have put a Spanner in the Works for resident Magnificent Bastard Lelouch's plans and as Zero he intends to do everything in his power to bring Kira down...

Provides Examples Of:

  • Affably Evil: Light is apparently "the best roommate a guy could have!"
  • Batman Gambit: Light controlled some Britannian bullies to attack Tarou while on the train so he would be saved by and befriend Suzaku for the sake of The Plan.
  • Decadent Court: Like in Code Geass canon the Brittanian royal family. After killing the Emperor and his heirs Light has a hard time finding someone competent enough to serve as his puppet.
  • Devil in Plain Sight: Light. He seems to realize this when Tarou is enthusing about him to Suzaku, about how his roommate is a genius and awesome and manages to affect some modesty.
  • Did We Just Have Tea with Cthulhu?: Cecile upon realizing that the guy In the Hood she just got a glimpse of was Kira and that he is offering them protection in exchange for her and Lloyd's obedience.
  • Do Not Adjust Your Set: Light sends a message to the media informing everyone that if the Brittanian forces don't leave Japan Kira will kill the royal family. Lelouch realizes afterwards that since there was no chance of Brittania ever bowing to such a demand the message was actually meant for him and his Black Knights. Kira was letting them know when to strike-in other words Kira used them.
  • Due to the Dead: This trope gets invoked when both the Britannians and the Black Knights are LOOKING REALLY HARD (cutting up corpses) to find the cause of the mysterious heart attacks.
