* The final four episodes. Sure, some may argue that it is a heartbreaking DownerEnding, but consider that Misuzu and her Mommy were closer to each other that one brief summer than most mothers and daughters ever will be in a ''lifetime.''
** Misuzu could have had [[spoiler: a long life of empty loneliness]] or a short one of deep love. The fact that she wound up with the latter was a triumph, and it's implied it [[spoiler: broke her curse]] as seen by the kids at the end. Also heartwarming beyond measure: that Yukito is willing to [[spoiler: sacrifice his humanity]] just to be with her for all of it.
** It's a BittersweetEnding in that, yes, [[ItWasHisSled Misuzu does die]], but thanks to Yukito, the curse she inherited by being [[spoiler:a reincarnation of Kanna]] was broken. Same as the previous statement, except that [[spoiler:it was never specified if breaking the curse breaks the chain of reincarnation, so Kanna/Misuzu should be happy in their next life]].
* Watching Haruko and Misuzu grow close in the TV series and even seeing them start off close in the movie.
* HeartwarmingInHindsight:
** In ''AIR'', Kano has the wish to be able to perform magic; you will feel happy for her if you have played ''VideoGame/EternalFighterZero'', where she fights with [[MagicStaff a fantasy role-playing staff]], and is able to cast tiered versions of [[FireIceLightning fire, ice and lightning]] spells, as a reference to an [[RolePlayingGame RPG]] named ''VideoGame/RagnarokOnline'', then you realize that her wish became true.
** So, Misuzu dies at the end, [[spoiler:and the story ends with the implied HopeSpot that her curse was broken, and she will finally get the happy life she deserves in her next life.]] Like Kano's example above, you will feel happy for her if you have played ''VideoGame/EternalFighterZero'', where she looks pretty happy with her new fighting skills (And for this same reason, you will also feel happy for Kanna, if you're familiar with the [[spoiler:Misuzu]]/Kanna link and story, you don't mind her SNKBoss status).
