"Stories like this don't have happy endings."
Benny, Episode 15, "Swan Song at Dawn"
- The end credits music, at least until the very end.
- The deaths of Hansel and Gretel. Since the series usually consist of over the top action scenes where dozens of Mooks are gunned down by our heroic sociopath "heroes" without a second thought, an arc that could actually be taken seriously was a severe case of Mood Whiplash. The arc following it was so over the top ridiculous that it actually seemed like an apology to the viewer for putting them through that.
- The worst part? That was about as close to a happy ending as they could get. The only way to improve it would be for Hansel's death to have been less painful. That is how screwed up these two were. They are little kids.
- There is a reason the ending of episode 15 is different from normal. Every time you listen to The World of Midnight tears start flowing.
- The moment it sinks in for Hansel that he's NOT going to live and his entire worldview was a lie. He lies there in silent shock, struggles to get up one last time...and then just gives up and breaks down sobbing, while slowly bleeding to death. Even Balalaika seemed to pity him at this point...and she's the one who ordered for him to be killed!
- The entire reason their worldview exists in the first place. Hansel and Gretel were kept alive as pets for the mafia for added entertainment in Snuff Films, and the only reason they weren't killed with the other children is because they themselves were used as the executioners. Eventually they just accepted it with the justification that the entire world had to work that way, that their lives were extended for every person they killed. It had to work that way, right? Because otherwise, they would've had to deal with the fact that the people responsible for their terrible trauma were simply that evil and heartless, and worse, that every terrible thing that was done to them happened for no fucking reason at all. Their worldview was a safety mechanism. That worldview was a safety mechanism.
- The scene pictured above is a huge example: The one lying on the ground, all blood-covered, is Gretel. Her Laser-Guided Karma reaches her right after she has revealed her Dark and Troubled Past and Hidden Depths to Rock (the latter in an horribly twisted way), and had one of her biggest wishes (going to the seaside) fulfilled. An Hotel Moscow Punch-Clock Villain shoots the girl dead as soon as she goes into the harbor, and she dies saying that the sea and the sky are really beautiful.
- Worse still, the ending of the Tokyo arc, the deaths of Yukio Washimine and Ginji Matsuzaki, and Rock's apparent realization that he's one of the bad guys now.
- The omake that features Yukio and her classmate Maki can come off as this, especially after the major Downer Ending.
- That arc also gives us Balalaika's Start of Darkness. It's especially poignant when you realize that the song playing while Balalaika decides to join the Mafia is the same song that played during Hansel and Gretel's death scenes.
- And it's not just the ending or Balalaika's backstory. There's also the scene with Yukio telling her kouhai Maki good-bye and asking her to take care of her mother, before she abandons her school and takes over the clan. That leaves the poor girl in tears and screaming "Sempai, sempai!" as Yukio leaves her.
- Revy's face when Rock tells her that despite what she thinks (that he's a normal person who could go back to a normal life) that he's just as messed up as her and right where he belongs. It's like she can't tell if she should smile or cry.
- This is anime only, but at the end of Roberta's Blood Trail, upon seeing the Nigh Invulnerable Ninja Maid reduced to a half-blind wheelchair-bound cripple with one arm and leg missing one can't help, but feel sad.
- Near the end of the Hansel and Gretel arc, Gretel tells Rock what she and Hansel went through, relaying her bleak, nihilistic philosophy about life and the world. Absolutely horrified, Rock gives her a hug and tells her that the world can be a beautiful place and should be a beautiful place, especially for children like her. Unfortunately, having had her humanity stripped from her at such a young age, Gretel doesn't respond in the most healthy of manners. Given how disturbingly common Hansel and Gretel's situation was in Ceaușescu's Romania, it made even jaded viewers feel something in their eye.
- The quote above comes from Benny and Rock's discussion about what happened with Gretel. Rock explains it to Benny and says he wants to help her, but Benny is bitterly aware that she's already damaged to the core and tells so to Rock without pulling any punches.]]
- During the Lock-and-Load Revolution arc, after a particularly over-the-top car chase/shoot-out full of snarky back-talk between Revy and Shenhua, sudden Mood Whiplash:
Takenaka: Ibrahim! Don't forget we have a job to do! IBRAHIM! No matter what you do, or how hard you fight, your son is never coming back!
- The last third of episode 15. Oh God. Also, Episode 24, though maybe not as much.
- "DON'T LOOK AT HER, ROCK! LOOK AT ME!" (Rock doesn't)
- Revy's monologue about how she has such a nihilistic world view in the "Das Wieder Erstehen Des Alders" arc, particularly when a Dirty Cop beat and raped her, how she killed her father and that if Rock ever tries to tell her if she's acting immoral by looting corpses, she will kill him. It's as tragic as it is chilling.
