Bleach really isn't for kids twelve and under, but there's still some things you can't run in Shonen Jump or on primetime TV. What's more, some of the Crap listed below isn't edited out in the English versions of the anime or manga, which are generally held to stricter content standards.
Chizuru, being an openly lesbian Genki Girl, is the source of a lot of stuff, especially early on. In an attempt to bowdlerize her open Skinship Grope of Orihime, the animators had her hugging her from behind... but there's still quite a bit of focus on Orihime's Gag Boobs.
The English dub of the anime managed to sneak in a good one. When Urahara picks up cat!Yoruichi and plays with her, in Japanese he just says Baby Talk-based nonsense. In the dub, he says "Who's my favorite pussy?" It becomes worse/better/whatever when you find out/remember Yoruichi is female, as she has a deep masculine voice in cat form...
The execution method in Soul Society, and the one Rukia was this close to undergoing. You're restrained and suspended by your limbs, completely helpless... and then you get impaled by a special halberd named Sokyouku.Which bursts into flames before taking the shape of a phoenix. Subtle much, Kubo?
The whole X-Cution arc was an exercise in how much crap Kubo Tite could sneak under the Shonen Jump censor radar at full speed:
Jackie Tristan's Fullbring is blatantly a dominatrix outfit, and her attacks get stronger when her boots get dirty. "Sand, dirt, mud, blood, [other bodily fluids] anything will work." Taken even further later: when she's powered up by Ginjo, her Power Armor covers almost her whole body except for her face... and her crotch.
Riruka Dokugamine, the other female Fullbringer, sneaks another one. She pretty much states that she's in love with Ichigo the first time she sees him. Her power? She can put things in her "dollhouse" if she grants them permission and she likes or loves it. And it can only be let out if she gets it wet...
And with a sneeze, to make matters worse. Several urban legends associate sneezing with ejaculation and sex.
And in this shot◊, it's clear that she's wearing another G-string (because it's confirmed she does wear underwear when Yukio complains the method she uses to kick open doors shows her panties). Unless of course she decided to go commando today.
It gets better. Tsukishima's power is rewriting your memories and inserting himself into them — as someone whom you dearly love. How does he use it? Via running you through with his katana. In few words, he penetrates you with his sword and is so good at it that soon you're fawning all over him. Now, where the FUCK are the NTR doujinshi with this guy, damn it?
Szayel Aporro Gantz is an expert in this. How does he keep Mayuri's assistant and "daughter" Nemu in place? With Combat Tentacles. How does he revive himself? Via forcing what's left of him down her mouth, invading the girl's innards and bursting out of her stomach, as she pleads for him to stop. That particular scene was so chock-full of rape imagery that it's a freaking wonder Shonen Jump was willing to publish it.
Taken Up to Eleven when we learn that his Hollow hole is in his penis.
How about up to twelve as it was followed up by Mayuri's method of reviving Nemu?* Nothing was ever shown, but she starts moaning almost as soon as he starts healing her. The anime, especially, did not help matters with Nemu screaming with pleasure.
When Nnoitra restrains Orihime to force her watch Tesla beating the shit outta Ichigo, he sticks his fingers deep into her mouth to keep her quiet. While it's not well known in the West, sticking one's fingers up and into somebody else's mouth is a pretty common kink in Japanese porn (and often seen in hentai). Any doubts about Nnoitra being a Memetic Molester were left behind at that point.
Not to mention that he calls her "pet-sama" (lady-pet)" or "my pet" literally every time he speaks to or even mentions her. He even admits to Ulquiorra that he wants to rape her, and Ulquiorra (who, mind you, is a merciless Manipulative Bastard) is all "... the fuck?!" at that.
The fourth movie has a five second long shot of Rukia naked and in chains, with the objectionable parts being covered with lava. She gets a white robe a second later, but it's still impossible to miss.
Chapter 519: Tenjirou tosses Rukia, Byakuya and Renji in his Healing Springs to cure their massive injuries. As a result, Rukia is floating on her stomach in the water — and the only parts of her body we clearly see are the back of her head... and her naked ass.
Tenjirou even asks Ichigo if seeing her naked puts him in the mood for "peaches".
Chapter 535: Masakiis naked throughout the entire chapter, it's offscreen for the most part but towards the end we do get rather generous shots of her breasts (with Barbie Doll Anatomy) and her bare ass.
Chapter 536 continues where 535 left off and we get another shot of her breasts...this time with no censorship whatsoever.
Chapter 540 has the debut of Ouetsu Nimaiya's really cute assistants... and they announce themselves as "Nimaiya's Private Escort Team"... Classy, Kubo.
In chapter 567, Rukia gets a... rather provocative◊ cover page. She's looking over her shoulder and seems to be she's sweating, to start... her cute dress leaves her back almost completely exposed, her hands are pressed down and her hips are bent in a way that leaves ass lifted up, she has a dark shaded area on her ass that resembles a thong, and the general positioning makes it look like she's about to have sex.
Back to Chapter 119, Orihime stripped two random Shinigamis (a man and a woman) to steal their uniforms so that she and Uryuu can disguise as Shinigami while infiltrating Seireitei. Both poor random Shinigamis are forced to lay down on a covered floor (making it resemble a mattress) while their (much likely) naked bodies are covered with just one blanket shared for two of them. Couldn't it be more subtle?!
Chapter 588: Yumichika accuses Giselle of supposedly being male, even saying that s/he reeks of semen! This can be easily read as Yumichika dropping a Gender Reveal — or as him off-handedly accusing Giselle of sleeping around. The fact that neither accusation is immediately dispelled (the very pissed off Giselle brings Bambietta's zombified corpse to the battlefield instead) makes one wonder...
