But, as the cast of Code Geass isn't exactly known for following rules, V.V. decides to stack the deck by sealing away C.C. before the War in order to prevent her from stopping Instrumentality. C.C. does not take kindly to this, and upon her release during the Shinjuku Incident, appoints Lelouch as the 8th champion of the War - Avenger, the wielder of Absolute Retribution.

In other words, its a Code Geass / Nasuverse fic, with the story of the Black Rebellion set against the backdrop of the Nasuverse itself. Characters from Tsukihime, Melty Blood, and Fate/stay night as well as from KNK also appear in the story and have roles that affect the plot in some shape or form.

  • Tags: AU for Code Geass Canon. Rated M (mature audiences)
  • Comments: Fans of Soul Chess who are familiar with Fairy Tail should be - if they aren't already - all over this story. The author himself has stated that he is much happier with this story than the majority of Soul Chess. And it really shows. His characters are near-flawless, the fights have almost drastically improved, the plot feels a lot more well thought-out... If you're looking for a new long-running series under draconichero's name, this is the best choice.
