YMMV / The Tailor of Enbizaka

• Broken Base: There's a strong split regarding the novel's final twist that Kayo killed Kai and his family not out of yandere delusions as was stated in the song, but because she realized he was the one responsible for her family's death. Some fans are pleased because it gives more depth to the motivations of the killings that wasn't there before, whereas some fans are upset that the story they came to know from the song and were excited to see is technically canon for another universe. In addition to that, there's been several debates over whether or not what Kayo did can now technically be called Envy, what with her motivations being ostensibly revenge based. Notably, the latter debate actually appears in the story itself.
• Captain Obvious Reveal: The reveal that Gakusha is Kayo's husband is hinted at so heavily that it almost seems like an anti-twist, with the way its presented, one might be surprised with how late the reveal actually occurs in the story.
• Ensemble Dark Horse: While the book is very dividing among fans (mainly due to one rather infamous twist), most fans agree to loving Kokutan and his party, especially Saruteito, even though they get a relatively little amount of screentime.
• Fanon: After the twist in the novel, a lot of fans like to interpret the Tailor of Enbizaka song as being a representation of the alternate timeline where Kayo really did kill Kai out of envy, albeit in that timeline Kayo wouldn't have been in Lukana's body. Others view the song as being a representation of Kayo's false testimony.
• Heartwarming in Hindsight: The narrator, who is actually Kagura and not the Demon of Envy, hopes in the end that Kayo will be happy in death even if she falls into hell. Readers view this as a tragic wish, since as a "demon contractor" Kayo's soul doesn't have very good prospects. But we learn in the final novel that Gumillia actually did spare Kayo from hell out of favoritism, in essence granting Kagura's wish.
• Jerkass Woobie: Kiji Yarera. The Jerkass part comes when he fully intends to murder someone on the idea that they might be responsible for killing his love, and his rude behavior towards Kokutan and his friends. (Besides which, the Yarera family has never been completely clean morally.) The woobie part comes in when you remember that his wife and unborn child have both been murdered by someone and the police have no leads at all.
• They Wasted a Perfectly Good Plot:
  • The reaction of at least half the fanbase when it was revealed that the story was never about Kayo's madness in her song but rather a revenge scheme, with some feeling that the song's story and mental state was interesting in its own right and deserved to be expanded upon.
  • The fact that Kokutan never gets to meet or interact with the Miroku family, particularly Rin (even if him not meeting Rin was intentional.) Some of the fandom felt it wasted Allen's presence and prevented interesting development, as well as being unnecessary angst for Rin Miroku as Riliane.
• The Woobie:
  • Kayo. From the beginning, she (at the age of 16) loses her husband and infant son to a horrific fire, suffers significant mental scars due to the event and is taken by her family who, after learning she lacks the Octo family treasure, kick her out and leave her at her old home with absolutely no support. Needless to say it gets worse from here.
  • Kokutan-douji, considering that he ends up having to execute a woman who was like a mother to him and fails to meet his sister again, which is the whole reason he reincarnated to begin with.
  • Rin Miroku also qualifies for similar reasons—not only does she lose her mother and her sister in quick succession, but she is also Riliane's reincarnation and was born with the constant feeling that she was waiting for someone—namely Allen—throughout her life. When she regains her memories, she expresses determination to stay alive just long enough to meet Allen again and tries to fight Kayo with the help of the Demon of Pride...only for said demon to not respond and Kayo to murder her.
