History TearJerker / DuskMaidenOfAmnesia

** If you think a little deeper about it, it gets even worse. He was there the whole time. The ''whole'' time, and could feel everything she felt. Remember, she didn't die of blood loss, nor was she [[MercyKill Mercy Killed]]. It's pretty clear from her physical appearance (the dried and drawn back lips, the shaking, etc) that she was dying of ''starvation and thirst'', and that he had to watch ([[FridgeHorror and feel]]) the love of his life die that long, slow death, while dealing with a broken leg that has a ''[[BodyHorror a bone sticking out of it]]'' for days. Dying of starvation and thirst on its '''own''' is incredibly painful, dealing with a broken leg, with a '''[[NauseaFuel bone sticking out of it]]''' [[NightmareFuel at the same time]]... [[UpToEleven On top of that,]] you have what's mentioned above about not being able to do anything about it, or even give her any form of comfort as she lay there, [[DyingAlone dying, alone,]] literally finding out [[WhatYouAreInTheDark what she is in the dark]], and almost giving in.

** And then she reappears.
* In the manga, Yukariko having a change of heart too late and falling down the stairs right into her sister's lap. Then being so ''[[PleaseKillMeIfItSatisfiesYou happy]]'' when the vengeful ghost tries to strangle her. Which Yuuko ultimately couldn't, because beneath the hate Yuuko still loved her sister too much to do it.

* Episode 10. All of [[TroubledBackstoryFlashback episode 10]] is either this or Nightmare Fuel. You get to see Yuuko before the human sacrifice, and she's one of the nicest people you could hope to meet. [[BreakTheCutie And]] [[HumanSacrifice then...]]

* Just... The fact that Yuuko's been wandering around the school, completely invisible, and when seen at all she's seen as a horrible monster, ''for decades.'' It's no wonder she became so attached to Niiya so quickly. He's the only one she has.

Then being so ''[[PleaseKillMeIfItPleasesYou happy]]'' when the vengeful ghost showed up to strangle her. Which she couldn't, because beneath the hate Yuuko still loved her sister too much to do it.

** Then there's Yukariko, who has been [[spoiler:living with the guilt of killing her own sister for all that time]]. It probably doesn't help that Kirie looks so much like Yuuko.

* Last 1/4th of episode 12. [[spoiler: Yuuko finally disappears.]] The music didn't help any.
** And then [[spoiler: she reappears.]]

* [[spoiler: Yuuko's disappearance is in so many ways much worse in the anime than in the manga.]]
** [[spoiler: Anime!Yuuko doesn't want Keiichi to watch her disappear, so she begs him to leave before she does. Keiichi refuses, so they waste a lot of their last time together arguing back and forth. Manga!Yuuko disappears much quicker, so she barely has time to reach out for Keiichi before fading away.]]
** [[spoiler: Since Anime!Yuuko disappears gradually rather than instantly, the couple spends their last moment visiting the place they first met. Mid-way through, however, Yuuko's voice disappears. Keiichi can only communicate with her through a notebook. Soon after, her visage disappears, leaving Keiichi alone with only her writing as the last bit of her presence. The scene ends with the invisible Yuuko giving Keiichi a kiss. As soon as she vanishes completely, Keiichi is left desperately screaming out her name. The song requiem makes the scene so much more powerful.]]
