''Kamen Rider Kabuto'' is a part of [[Franchise/KamenRider a massive franchise]] created by ShotaroIshinomori (who also created ''{{Cyborg 009}}'') and produced by the Toei Company. Sure, you might have people wearing bug-suits to kill [[PeopleInRubberSuits Worms,]] but trust me, there are moments that are guaranteed to make you bawl. Need an example of depression from toku? Look no further than what happens on Series/KamenRiderKabuto:



* The truth about Kagami's younger brother in episode 4. Enough said.
* The entire [[spoiler: parting between Daisuke and Gon]] in episode 18 is merciless. [[spoiler: Not only has the show just spent two episodes on a whole betrayal and reconsilation arc between the two after they have a falling out and Daisuke rescues her from ZECT... we then actually find her mother. Daisuke fights to save them from a Worm, and after defeating it, stops by while in Clock Over mode to see Gon (Yuriko) tearfully happy to see her mother - and actually catches one of her tears in Clock Up mode before he just turns and leaves them. And then a few days later, he meets them on the street, and Yuriko doesn't recognize him. Her mother tries to remind her, but Daisuke just says that there's no need, and she was simply so cute he couldn't help but call out to her, trying one of his many compliments again... and being unable to finish it without her helping him. It's heartbreaking all around, even if you are happy to see her reunited with her mother.]]
* Episode 22, when [[HeroicSacrifice Makoto sacrificed himself]] to protect Kagami from ZECT detonating Worm eggs. I can't imagine how Kagami felt after watching a six-year old boy die from the blast. [[spoiler: Well... he is actually a Worm, but that's beside the point.]]
* Daisuke Kazama is forced to kill [[spoiler:Rena Mamiya when she reverts to the Uca Worm and threatens to kill Gon]].
** One can argue that Rena's "performance" in front of an empty house in Episode 40 is mind-numbingly depressing as well.
* When Tendou finds out that his sister Hiyori [[spoiler: is in fact a Native that prefers to be with Souji Kusakabe (Dark Kabuto,]] he draws dangerously close to [[HeroicBSOD abandoning his battle against the Worms altogether.]]
* [[spoiler: Kamashiro Tsurugi (aka Kamen Rider Sasword)]] turning into the Scorpioworm in front of Misaki in Episode 45 was not only scary but [[FridgeHorror also depressing when you realize that this]] killed any hopes for [[DidNotGetTheGirl him to get the girl.]]
** And then, in episode 46, [[spoiler: Tsurugi]] realizes the truth not only about himself, but also [[spoiler: how he killed his sister when he was still the Scorpioworm.]]
*** The result? [[HeroicBSOD He tears his gifts to Misaki, throws away a christmas cake, and breaks down at a beach.]] He then believes that the only way to get over this tragic discovery is [[DrivenToSuicide to kill himself]] by pretending to [[FaceHeelTurn become hellbent on destroying ZECT.]] Boy does it suck to be [[spoiler: Tsurugi in episode 46.]]
*** It's even worse if you remember that Kagami knew all this time that [[spoiler: Tsurugi]] was a worm and yet never told Misaki when he was going out with her.
* Speaking of which, the scene from episode 46 when Tsurugi tells Misaki his dream date with her is absolutely gut-wrenching.
** The worst part? This heartbreaking monologue came just as [[JerkAss Hyper Kabuto (Tendou Souji)]] was preparing [[spoiler: to finish Tsurugi despite Misaki's pleas to keep him alive]]. God damn you Tendou for [[spoiler: killing the best character in the entire series.]]
** And last, but certainly not least, [[spoiler: Tsurugi]] dies in [[spoiler: his butler Jiiya's]] arms. The last exchange between the two? "Is it okay if I go to sleep?" "Of course. Please don't worry about a thing. [[spoiler: Jiiya]] will always be by your side." [[PrecisionFStrike Fuck...]]
*** And the nail in the coffin? This episode aired on December 24th. Imagine, so many Japanese children going "Oh boy, Christmas Eve! Time to watch the new Kabuto episode..." and then watching all of the above happen.
* Episode 48... oh boy, Episode 48... sniff...
** First, we get flashbacks that show [[spoiler: Dark Kabuto being converted into a Native and forced into brutal experimentation]] WHEN HE WAS JUST A YOUNG BOY.
** And when you think it couldn't get any worse, [[spoiler: Kageyama kicks the bucket]] promising to be by his [[HoYay Aniki's]] side... Damn.
*** It's even more depressing when it was [[spoiler: [[BigBrotherMentor Yaguruma/Kick Hopper]] that had to kill Kageyama]] with his [[FinishingMove Rider Kick]] when [[spoiler: Kageyama's necklace turns him into a Native.]]
* [[spoiler: Souji Kusakabe's]] HeroicSacrifice in the finale... Japanese households must have ran out of Kleenex when the kids watched that scene [[WhatDoYouMeanItsForKids on TV Asahi's SUNDAY KIDS BLOCK.]]
* The ''MOVIE'' of all things when Hiyori [[spoiler: dies just after she and Kagami had been announced to be wed]]. Both Kagami and Tendo suffer from an enormous HeroicBSOD from this.
** [[spoiler: This loss is what drives Tendou through the rest of the movie, as he plans to steal the Hyper Zecter to travel back to 1999, destroy or diminish the meteor, give the Earth more of a chance to fight the Worm, save Hiyori, and motivate his past self to earn the Beetle Zecter and prevent this tragedy from happening.]]
