  • This chapter introduces NICODE and Mai Aoyagi.
  • The font used for both the title and artist name is Exocet.
  • The story is based off of the two girls from the Holy Knight cover, Iris (blue hair) and Rosabell (red hair).
  • Like Chapter R, Chapter T, Chapter M and Chapter L, the songs have different names in the song selection menu.
    • Like Chapter T, song icons are featured in the cover art for each of the songs in this chapter.
  • The Fallen Bloom is the only song outside of Cytus Alive to have a cutscene, and the only song to have its cover change permanently after it is completed for the first time.
  • This is the only chapter where all of its songs have been fully transferred to Deemo, Rayark's second rhythm game. They are split in two separate collections: the Knight Iris collection, which contains the first five songs of this chapter, and the Knight Rosabell collection, which contains the latter five.
    • In version 2.3 of Deemo, Chapter L has had its songs transferred to the game as well, though the versions used in Deemo are cut down in length.
  • In version 8.0, this chapter does not have any cooldown on its songs in the free version. This error was fixed in version 9.0.
