- Alternative Character Interpretation: Did Tsui Ling wish for Kazuma to die for failing to protect her, or was Lapis lying? The death of the author sadly means that this issue will not be resolved.
- Base-Breaking Character:
- Ayano for some is a reasonable, hijinks prone heroine, or an annoying foil to others.
- Kazuma is either one of the most badass characters in the series or a total douchebag.
- Complete Monster:
- Michael Harley is a member of the Stars of Sagacity who was sent to kill Kazuma Yagami. Upon meeting Misao Oogami, he exploits her desire to avenge her fallen brother by having her kill hundreds of innocent people slowly draining their Yoki; among those victims are Misao's own family members. When they gather more than enough Yoki, Michael reveals his true motives to Misao of using the Yoki to turn her into a medium, saying that he did not care about avenging her brother; this drives Misao mad with remorse. Michael then proceeds to forcibly transform Misao into a dragon and send her to kill Kazuma, while threatening him that if he kills the dragon, he would also be killing Misao.
- Bernhardt Rhodes is Kazuma's Arch-Enemy and the leader of Armagest, the organization responsible for sacrificing Kazuma's First Love, Tsui Ling, to the demon king Belial. He then proceeds to use the remains of Tsui Ling to create a clone called Lapis using her to psychologically torment Kazuma, and later has Lapis destroy an entire building of innocents while escaping Kazuma. He also created "Pandemonium", where he would send demons to inhabit numerous teenagers, empowering them and having them fight each other to the death. He would then forcibly turn the survivors into demons, before sacrificing them to Belial in hopes of releasing him. While seemingly wanting to avenge the death of master, Erwin Leszaa, it is soon revealed that Bernhardt doesn't really care about Erwin and is tormenting Kazuma for his own amusement and plans to use Belial to destroy him, his city, and everyone he holds dear.
- Harsher in Hindsight: Following the defeat of Belial by the main trio of characters in the fifth story arc, Bernhardt Rhodes proclaimed that this wouldn't be the last time he and Kazuma would confront each other. Actually, they wouldn't be able to meet each other again.
- The Scrappy: Ayano has her fair share of detractors, who find her tsundere nature more annoying than funny.
- Strawman Has a Point: When the Fuga Clan is revealed to have been behind the murders of several Kannagis and have also kidnapped Ren, Kazuma blames the Kannagi Clan for having brought it out on themselves due to their derisive treatment against Wind-Magic Practioners and other non Fire-Practioners.
- They Wasted a Perfectly Good Plot: Jesuotaku in her review of the series accuses the producers of the anime series of this, particularly noting that the first arc could have been used as an entire season unto itself.
- Unintentionally Unsympathetic: Most of the Kannagi Clan during the Fuga Clan's Roaring Rampage of Revenge. Despite (A) the former's abuse of Younger!Kazuma, (B) their Hypocritical treatment of him upon his return, and (C) their Fantastic Racism at non-Fire Mages in general, the narrative still expects you to feel sorry — or at least shocked — for them. In fact, if the Fuga Clan wasn't also willing to sacrifice Ren, nobody would blame you for Rooting for the Empire.
- This is discussed in-universe, so the amount of unintentionality is debatable.
- Values Dissonance: Many western fans tend to be squicked at Kazuma and Ayano's relationship.
- An in-universe example occurs when Katherine experiences a first-hand culture shock in the Hot Springs Episode.
YMMV / Kaze no Stigma
