Oh nice this finally getting some translation. Hope this means more are soon to come and that the first manga will also get finished as well. This chapter is a bit hard to decipher given the first manga's ending isn't translated but from what I vaguely know of the plot going ahead it's an interesting start.
The final chapter part 1 that is also translated is way more understandable since it's directly connecting to the endgame of Code Geass R2. Still a bit confusing with the Cornelia thing since it's a bit weird since even if the anime had her somehow survive after being shot by Schneizel having Kanon be the one to save her feels weird?
