History Heartwarming / MyHeroAcademia

* Tsuyu's bonus chapter after Chapter 84, where we learn the origin of why she insists on being addressed by her first name: [[spoiler: She had a hard time making friends because she always had to help out around the house, along with her classmates being unable to read her perpetually neutral expression. She then met a snake girl named Mongoose, who she quickly became friends with. When Mongoose asked Tsuyu if she could address her by her first name, it gave her the idea that it was a sign of friendship]].

* In Chapter 83, when Midoriya wakes up in the hospital, nearly everyone in class shows up to see him. The only ones who aren't there are the Yaoyorozu, Jirou and Hagakure, who are hospitalized themselves, and Bakugou, who [[spoiler:was abducted]].

* Chapter 73 has Midoriya asking Todoroki if he knows a way to get through to Kouta to help him with his anger, while Todoroki tells him that while he does need to try empathizing with Kouta first, Midoriya is the kind of person to help others without even meaning to with his actions.

* The next chapter, Momo nearly loses because of a mistake and expects to be reprimanded for her slip. Eraserhead told her that he was the one that screwed up and that she earned her victory. The thing is, Momo did slip at one point and it was pure luck that she managed to pull it off anyways. Aizawa decided to let her have her victory without criticism so that she could get her confidence back again.

** And before that, Aizawa-sensei actually pausing in his villain act [[WhatTheHellHero to give Todoroki a mini-lecture about how inconsiderate Todoroki had been to Momo up to that point.]]

-->'''All Might:''' [[spoiler: You can become a Hero!]]

* In chapter 63, Todoroki telling Momo that he was the other person who voted for her to be class president, because he believed in her. This is part of what helps her start to get her confidence back.

** And before that, Aizawa-sensei actually pausing in his villain act to give Todoroki a mini-lecture about how inconsiderate Todoroki had been of Momo up to that point.

* In chapter 63, Todoroki telling Momo that he was the other person who voted for her to be class president, because he believed in her. This is part of what helps her start to get her confidence back.

* In chapter 60, after swiftly losing to Tokoyami in the sports festival and spending more time as a MsFanservice than a crimefighter during the work experience week, Momo is obviously feeling very down on herself as an aspiring heroine. As a result, seeing her face light up when her fellow classmates turn to her for help with studying for the finals (since she has the highest grades in the class) is just precious.

* As Midoriya's week with Gran Torino is up, he asks Midoriya his hero name to remember, reflecting that Deku is likely going to be a great hero in the future.

** The Cherry on top is that the first hero who outright stated interest in having Shinsou as a sidekick looked like a dragon-human hybrid with wings, so his Heavy is likely a combat focused one. That such a guy would honestly appreciate a more passive quirk like Shinsou's enough to want to help mold him as a hero in the future is very touching.

** Todoroki then pays it forward to Iida, inwardly sympathizing with the sort of tunnel-vision that hatred can cause. Outwardly, he snaps at Iida for refusing to accept his friends' help, and tells Iida that if he wants to stop them from helping him, he should stand up himself and be the hero he wants to be. The narration and Iida's inner thoughts imply that this is something of a HeelRealization moment for him, as he realizes that his RevengeBeforeReason antics haven't been properly honoring his brother's example.

* Chapter 53 reveals how much Midoriya has helped Todoroki. He was able to overcome his issues enough to not only visit his mother, who was back to her loving and supportive self, but signed up with his father's hero agency for the work experience. Not because he's ready to ''forgive'' Endeavor, but because Todoroki has grown comfortable enough with himself to acknowledge that, as big a scumbag as he is, Endeavor is still No. 2 hero after All Might, and thus there is a lot that he can learn there.

** Todoroki decides it's finally time to go see his mom for the first time in years to talk to her about how they've both been.

* In chapter 37, Uraraka's dads words of encourgment to his daughter who is depressed after her loss.
** Ironically, Bakugou praises Uraraka when people comment on how harsh he was to the "delicate" Uraraka
-->'''Bakugou''': Delicate my ass.

* Chapter 43 has several good moments:

** Next chapter turns it up even further. When Midoriya is questioning if someone else should have been chosen for one for all, All Might reassures him by telling him about how he also was born quirkless, and how Midoriya is the best candidate for the ability because he exceeds all of All Might's expectations.

** From the same chapter, All-Might doesn't praise Deku for trying so hard to the point of injuring himself severely, but he does praise him for putting Todoroki's psychological well-being over his own success. All-might claims that is what a real Hero does.

* Chapter 40: While it was expected of Uraraka and Tenya to visit Midoriya [[spoiler: in the infirmary after losing to Todoroki]], Tsuyu and Mineta join them too. It shows that a friendship sparked between them during the Villains Invasion Arc.

* Chapter 39 combines this with a moment of awesome for Midoriya. He calls Todoroki "fucking pathetic" for making excuses to not use his fire powers, and at the end of Todoroki's flashback we see that [[spoiler: he was a fan of All Might as a boy, too. This is right before he finally lets his left side ignite for probably the first time.]] All Might and Todoroki even note how strange it is to have someone helping their opponent during a match.

-->'''Oda:''' The same person who, as a boy, submitted this postcard, is now a widely recognized and extremely successful professional mangaka himself!! Not only that, but his work actually ended up being serialized in the Shonen Jump magazine right alongside "ONE PIECE" itself!! This news gives me ecstatic joy. You see, a bit back at the Jump new years event, he himself actually came forward and told me about this. You should've told me earlier, I would've totally rooted for you!!

* On a more meta level, there's the fact that Eiichiro Oda of One Piece opened the volume 77 SBS by showing fanart Horikoshi submitted ten years ago that was feature in a volume.

-->'''Bakugou''': Delicate my ass.

* In chapter 34, after Shinsou's flashback over everyone saying he'd make a good villain, the audience and his classmates congratulate him on his match and tell him he'd make a fantastic hero.

* Chapter 27: Despite the huge target placed on Midoriya's head after getting the highest bounty, Uraraka, who wanted to win the competition for her family, was still willing to be his partner.
