Heartwarming: Hunter Hunter

I'm the one who's glad that I got to meet you...

  • Killua vowing to protect not only his little sister Alluka, but also Nanika, her wishgranting alterego. Especially since this was seconds after Killua told her to never come out, and reduced the poor thing to tears. After being called out on this by Alluka, Killua tells Nanika he was wrong and he'll always protect both of them, before tearfully asking for her forgiveness. She forgives him.
  • Gon telling Killua how glad he is that he met him and Killua thinking that Gon has it backwards.
  • "Gon....you are light."
  • Leorio and Gon reuniting after Gon's life is saved by Nanika. It's the midair hug that really sinks it.
  • Kurapika revealing his powers to Gon, Leorio and Killua. The act of doing so was a great risk. One of the Troupe members, Pakunoda, had the power to read minds. If they were to be captured and Pakunoda were to read their minds, all of Kurapika's weaknesses would be exposed. Gon begs Kurapika to point a nen arrow at his heart so that it would kill him if he were to reveal his secret. Killua and Leorio follow suit, agreeing that it was a good option. Kurapika, however, refuses their offer. He says that he would not mind it even if they somehow managed to reveal his secret. He had good friends ..
    • Before this point, Kurapika is extremely depressed because he believes that the Phantom Troupe had been eradicated, eliminating his primary endeavor. Kurapika has not seen Leorio, Gon and Killua for six months, and soon he reunites with the others at a park. Gon and Killua are having an ice-cream eating contest when he gets there, and, on sight, it is obvious that Kurapika is upset. Gon cheerfully tells him that he should be happy. Now that he doesn't have to worry about the Troupe, he can comfortably recover all of the eyes of his murdered Clan. Then, as Kurapika gets over his shock, Killua promptly shoves a pie in his face. Enter Leorio, and Kurapika laughs for what might be the first time in a while.
  • At the end of the Greed Island arc Gon decides the first thing he's going to do when he meets his father for the first time? Introduce him to Killua: his best friend.
  • Chapter 339. That is all.
  • Meryem goes on a speech on how sociopathic he is and is about to kill Komugi, then he sees her being attacked by a hawk. He kills it and asks why she didn't ask for help, she answers she didn't want to bother anyone. It serves as heartwarming development of character for someone had previously being perceived as a complete psycho.
    • Their last moments together. Meryem went from someone who wanted to take over the world to someone who just wanted to spend the last few hours of his life playing a board game with someone he had come to care deeply about. When Meryem tells Komugi the poison is contagious, she tells him she won't leave his side and holds his hand when he starts to lose consciousness, thinking she'll be joining him soon.
      • "Goodnight Meryem."
  • From the first chapter, all of the forest creatures giving Gon a farewell before he leaves for the Hunter Exam.
    • And then after that, there's Gon saying goodbye to Aunt Mito. Made even more heartwarming in the 1999 anime when he tells her that as far as he's concerned, she isn't just like a mother to him, she is his mother.
    • In the manga, when Gon is listening to the message Ging left for him and the recording says that if he keeps listening Ging will tell him about his biological mother, and Gon shuts off the tape without a second of hesitation, knowing that the moment he shuts the tape off it will automatically erase itself. When Killua asks him why, Gon tells him that he doesn't care about who his biological mother may be, because in all other respects his real mother is Mito (and unbeknownst to him, Mito is listening in and hears this).
  • Kurapica cheering Gon up after a traumatic encounter with Hisoka on Zevil Island.
  • The lengths Gon goes to trying to rescue Killua from his crazy family. Kurapika and Leorio coming along to help is just icing on the cake.
    • From the same arc, we get to meet Canary, one of the Zoldyk butlers. The narrative takes its time noting that she sincerely wished to be friends with Killua even at an early age, but could not because the Zoldyks forbade real social interaction with him. So when he finally leaves the butler's quarters and passes her up without saying a word, it's a little hard to watch. But when Gon, who barely knew her but still saw her need to want to help Killua, cheerily says goodbye to her on his way out, it's the small smile on her face that she makes as Gon passes her by that makes it all worth it.
  • Gon and Killua parting ways with Bisky at the end of the Greed Island arc is this and a bit of a Tear Jerker as well. Gon asks her if she wants to come along to meet his father, but she declines, knowing she'll become even more attached to them if she does. They do eventually meet again in the next arc, but its still a very tender moment, and one thats even more touching in the OVA series, where she tells Gon and Killua they're the best and that she loves them. D'awwwww.
  • Melody in general. Her calming presence and Morality Chain status for Kurapika makes the duo's friendship meaningful and sweet.
