Beware of unmarked spoilers.
- Adorkable: Readers find Izuku to be cutely dorky due to his lack of confidence, easily flustered nature, stammering, eagerness, nerdiness, and long-winded rambles about how cute Uraraka's freckles are. He is also very passionate about hero stuff.
- Angst Dissonance: Some readers think Toushiro's PTSD is overblown or that he should not have PTSD at all despite the trauma he has gone through. I.e. he was tricked into stabbing his sister through the chest, got grievously wounded to the point of near-death multiple times, was forced to fight the flame-wielding Bazz B, was turned into a zombie and controlled by Giselle, and went through Mayuri's cure for his zombification.
- Anti-Climax Boss: Toushiro easily kills All-for-One in chapter twenty-seven, though it is hinted there is a Man Behind the Man who is sending Hollows and Arrancar to the pro-heroes' world.
- Arc Fatigue: Many readers became exhausted and frustrated with the "Toushiro keeps his and Hollows' origins a secret" arc/plot and impatiently waited for the inevitable reveal to happen. The repetition of "Toushiro breaks the rules, explains nothing, and gets in trouble for it" also made it drag on. It takes thirty-two chapters for Toushiro to finally reveal his secrets to the UA characters. In real-world time it took two years to resolve that plot point. Many reviewers voiced their relief that the story was moving forward at last.
- Catharsis Factor:
- Seeing Endeavor publicly humiliated by Toushiro and called out by Midoriya and Todoroki after he tries to get Toushiro sent to a mental institution left many readers cheering.
- To those who were frustrated that the UA students, pro-heroes, and police kept berating Toushiro for doing his duty because he was breaking their laws, him finally losing patience, calling them out for putting their laws above lives and declaring he was done placating them and would fight them if they kept getting in his way was extremely gratifying.
- I Knew It!: Many readers guessed Toushiro's cat is Yoruichi as soon as she appeared. The reveal has yet to happen in the story but has been confirmed via Word of God.
- Moment of Awesome: Toushiro kills All-for-One in one blow, without a fight. That's right, he kills the leader of the League of Villains, the villain who gave All Might his Game-Breaking Injury, with one strike.
- Ron the Death Eater: Endeavor starts out as a Jerkass Abusive Parent in the manga until his Character Development, but the fic's version strips all nuance and good traits from his character until he's a villain in all but name. Case in point, the fic's Endeavor is petty enough to try to commit a teenager to a mental institution because he lost to him. This was written after the manga Endeavor's Character Development, but the author still hates him and tells readers to enjoy the Endeavor Bashing in the fic, making it unlikely he will develop and change as he did in the manga. The fic's Endeavor exists solely to be an antagonistic force that stands in Toushiro's way, suffer humiliations and the reason you suck speeches at the hands of the protagonists, and be the target of more sympathetic character's scorn.
- Strawman Has a Point: Endeavor is painted as petty, immoral, and in the wrong for attempting to get Toushiro committed to a mental institution. Except while some of his reasons are petty, he's correct that Toushiro reacted with concerning and extreme violence and could threaten the safety of the other students if he has another outburst. Toushiro then proves his point by implying he could easily kill Endeavor and threatening to not come quietly if they try to take him. Yet readers are meant to see Endeavor as a completely wrong and unreasonable jerk who must be humiliated for his transgressions.
- Take That, Scrappy!: Readers who have not forgiven Endeavor for his abusive actions in canon cheered when Shouto gave him a "The Reason You Suck" Speech in front of a crowd and called him out for what he did to his mother. Toushiro's generally dismissive attitude towards Endeavor also gets cheers from these fans.
- Unintentionally Unsympathetic:
- Some readers think the UA characters come across as ignorant at best and incomprehensibly oblivious at worst in their reactions to Toushiro's duty to kill Hollows, Nomu and Arrancar. The UA characters know Hollows and Arrancar are not human, kill humans, and eat human souls, but continue to treat their deaths like acts of third-degree murder.
- A portion of readers find Toushiro to be unsympathetic and/or carrying the Conflict Ball since some of his problems exist primarily because of his own stubbornness. While he has PTSD and is duty-bound to keep Soul Society a secret, some readers grew frustrated as Toushiro got into trouble again and again, which he could have avoided if he simply told the heroes the truth and stopped trying to do everything alone. In contrast to those who were happy, these fans were less than pleased when Toushiro threatened to fight and kill sympathetic characters like All Might if they did not let him do his job. Needless to say, many readers were relieved when Toushiro finally stopped keeping secrets from everyone and revealed everything in chapter thirty-two.
- Wangst: Toushiro's problems in this story note can make him come across as whiny, arrogant, and ungrateful, with some readers thinking he's too stubborn and predisposed to violently reject other characters' genuine worry for his well-being to be a protagonist they feel sympathy for. Repeated plots of how many of his problems stem from his stubborn desire to do everything alone (when the UA characters are falling over themselves to accommodate for and support him) and his angst over that can elicit irritation instead of the intended sympathy from readers. In Toushiro's defense, he is a stubborn and moody teenager, though he denies that.
