* CreatorBreakdown: A minor example. The author was hospitalized multiple times due to the pressure to meet deadlines and developed poor health as a result. This led to the series being ending with an AbortedArc.
* IncidentalMultilingualWordplay: The Japanese word for "betrayal" is "uragiri" (literally, "a cut in the back"), making "backstab" the perfect equivalent.
* WhatCouldHaveBeen: Yuki was originally going to be female but was changed to be male due to ExecutiveMeddling, which prompted the author to make his past life female.
