* SpellMyNameWithAnS: In the manga adaptation she is called Nanashi, which is the Japanese word for "No Name".

* SpannerInTheWorks: He's largely responsible for shaping most of Kaori's past life as it was revealed that his attachment to her during her childhood made it impossible for him to bring her back to the mortal realm to reunite with her long-lost mother after she was separated from her parents.

* WhyDidItHaveToBeSnakes: They have a fear of mustard, in ointment form, when it comes to healing wounds, as shown in Volume 1 when Noname rubs it to their wounds. It resulted in them screaming in agonising pain that was so loud that it forced Suimei and Kaori to cover their ears.

* IdenticalTwinIDTag: While both wear the same outfit, the colours make the two distinct to each other. Ginme's clothing is coloured red, while Kinme's clothing is coloured blue.

!!Mortal Realm
[[folder:Kaori's Mother ('''UNMARKED SPOILERS''')]]
!!Akiho Muramoto
Kaori's biological human mother.

* EatMe: Her final fate during the flashback when Nyaa ate her, though it was all done as part of the funeral service, as the spirit realm's interpretation of funerals for humans is vastly different from how human funerals are often done. This is to store all of her thoughts and memories to Nyaa, enough to store it indefinitely so that Kaori will still remember her even in passing.

* StrugglingSingleMother: [[DeconstructedTrope Deconstructed]]. After her husband's passing, Akiho was saddled with the burgeoning task of taking care of her daughter, while she was cash-strapped, burdening her further with the responsibility that she was clearly not prepared. Then there's her uncle and aunt, owners of an inn who are both embezzlers attempting to steal whatever remaining life savings she has in her bank account and her cash card, under the guise of inheriting it for Kaori to have it in the future after her passing. What happened after Kaori disappeared from public view is her going through a path of self-deprecation of being a mother with little parental skills, though it was until she finally opened it all up to Nyaa.

* SomeoneToRememberHimBy: Gender inverted. Nyaa mournfully ate her in the past, but in return her entire memories and anything related to her lived with him, a fact unknown to Kaori herself.
