* The show averages about one of these (or alternatively a CrowningMomentOfHeartwarming) per episode.
* Probably not the saddest thing to happen in the series, but pretty much all of episode 10 is one. Nico the flowergirl is one of the nicest, kindest and generally happiest characters in the entire series, managing to match ''Ringo'' smile for smile. She's also completely insane. And then she dies.
** The reaction of Bolton is the real emotional knife in the gut since her kindness had been bringing him out of his angry shell, only for his leg injuries to keep him from protecting her.
** and to drive the knife further, the episode ended with Bolton delivering a painful DeathWail
* Episode 13, "The Past Rises Before My Eyes". Even before [[spoiler: Casshern's encounter with Braiking Boss]] or the revelations that came with it, the scene before the OP ("it's not your fault Casshern") lets you know that there's going to be some kind of heavy hitter.
* ''A lot'' of the later episodes fall into this category... but oh, God, the final episode, and the [[spoiler: deaths of Lyuze and Ohji.]]
* [[http://www.youtube.com/watch?v=kjUjR1zY68E The song sung by Janice]], which also plays several times after her debut.
* [[spoiler: Dune's death]]. He finally found Luna again, only for her to treat him like dirt [[spoiler: and refuse to even be there for him as he's dying. No wonder Casshern is furious at her right afterwards.]]
* The final ED, with every member of the cast sans Casshern lying around sleeping, [[FridgeHorror becomes a lot more depressing]] when [[spoiler: almost everyone in it is dead.]]
