YMMV / A Minor Miscalculation

• Big-Lipped Alligator Moment: Chapter 11 concludes with Nui listening to a few verses of Space Oddity on a radio in the bathroom (explicitly referencing the verse where the astronaut implicitly dies as her favorite) before accidentally killing Takiji Kuroido as he passes by in the hallway. Only the fact that she hallucinated Mataro in Takiji's place has any bearing on the plot - the rest is played off and never mentioned again.
• Harsher in Hindsight: Chapter 11 features a sequence with Nui listening to Space Oddity and killing someone. Shortly after the very next chapter's release, David Bowie passed away of cancer, rendering the sequence an accidental retroactive tribute.
• Jerkass Woobie: Nui, if her thought processes and interactions with Ragyo are any clue.
• Les Yay: Mountains of it between Ryuko and Mako. Their first full chapter together starts with Senketsu accusing Ryuko of getting aroused by Mako's head on her chest, and it doesn't get any less blatant from there. By the later chapters, it's clear that Mako at least has an open crush on her. They finally become an Official Couple in "Complicated Women."
  • Ryuko also seems a bit too eager to crack jokes about sexually dominating Satsuki, doing so at a Nudist Beach meeting and later in a conversation with Isshin — who, knowing that they're sisters and his own daughters, is suitably squicked.
  • Satsuki and Jakuzure have some when they're together (such as the latter absentmindedly stroking the former's hair in an early chapter), though it is much milder than the above examples. Which makes it all the more ironic when later chapters confirm that they're really hooking up and later explicitly have them doing so, long before Ryuko and Mako hook up.
• Shocking Moments: "Maelstrom" is twice as long as the average chapter (so far, only "Severance" has come close to matching its word count), focuses on Ryuko and Mako finally fighting Nui after twelve chapters of buildup, brings every loose plot point from the first twelve chapters together, reveals that Mako can fight on equal ground with Nui and Sanageyama is a Nudist Beach recruit, and ends with Nui unconscious in Nudist Beach custody, Aikuro missing in action, Satsuki hinting at her Heel–Face Turn early, and Mako seemingly ending her friendship with Ryuko over her failure to save Mataro.
• Unintentionally Unsympathetic: A lot of readers dislike and root against Isshin despite his Well-Intentioned Extremist tendencies being mixed with genuine care for his daughter. As of "Consequences", this proved to be somewhat intentional.
• The Woobie: Mako and her little brother, having lost their parents to Nui. And then Mako loses her brother, and Ryuko leaves for a week when she needs someone to talk to, and finally, The Reveal in "Consequences" rolls back any attempt she was making at recovery until several chapters later.
