* JokeCharacter: [[spoiler:Kaguya]] has terrible damage output and moves slowly, but her route, given that it needs to be unlocked first, =solidifies this with its [[DenserAndWackier considerably wackier tone]]. By the end of the first stage, she's convinced that the incident is a [[{{Lunarians}} Lunarian]] conspiracy, and it leads to a few fourth-wall breaks, references to other games (including other Kaisendou games), and overall more light-hearted dialogue.

* {{Cult}}/ScamReligion: Shiran has built one very loosely based on the teachings of the Buddhist monk [[https://en.wikipedia.org/wiki/Shinran Shinran]] whom she was ''supposedly'' a student of, gaining the following of various anxious youkai in the process, including the first group of bosses.
