Bokusatsu Tenshi Dokuro-chan (Club-To-Death Angel Dokuro-chan), released in English speaking countries as Bludgeoning Angel Dokuro-chan, is a small Japanese franchise consisting of 10 light novels plus one extra book, six "pairs" of Anime episodes, 3 volumes of Manga, and a Playstation II video game. The series centers around Sakura, a fairly nondescript Junior High student that was marked for death by God due to the fact that he will invent a form of immortality in the future that prevents women from aging after 12 years of age (creating "a pedophile's world", as one character comments). God sends Dokuro, an angelic assassin, back in time to kill him.But alas, Dokuro finds herself enamored with him and decides that she can prevent this horrible future by keeping him too distracted to ever stumble upon the method. However, due to her irrational nature, she ends up wrecking his life in the process. One Running Gag is that Dokuro does, in fact, kill Sakura... repeatedly. Usually if he touches her in a way she views as inappropriate... or says something she misinterprets... looks at her funny... is just there... but she always resurrects him immediately afterwards. Drama unfolds when another angelic assassin, Sabato, is sent to do the job that Dokuro is putting off and Dokuro ends up taking on a role as Sakura's "protector" (death by Sabato seems almost preferable).The series derives most of its humor from crossing every line in parodying the whole Magical Girlfriend genre (and plenty of other Anime tropes). In that in has quite a few similaries with Dai Mahou Touge, with which it shares the directing and screen-writing talents of Tsutomu Mizushima. Bokusatsu Tenshi Dokuro-chan manages to often be far more brutal in its violence though. Sakura doesn't just get killed, he gets splattered in the most creatively gory ways possible (it actually becomes comedy when he doesn't get killed). Along with completely shattering the masquerade and the total creepy honesty of most of the secondary characters, it certainly is a unique show.
Abuse Is Okay When It Is Female on Male: Dokuro-chan takes this trope Up to Eleven. It's also one of the few cases where this is Played for Laughs... and we laugh. It isn't limited to that, however, making it a subversion of this trope. To date Sakura has been abused by his male classmates, male animals (who were formerly classmates), his male teacher, his father (in the manga) all for the sake of giggles. Sabato also endures hilarious amounts of abuse and misfortune.
Accidental Pervert: Sakura almost never has any overt sexual thoughts when he provokes Dokuro's wrath. In fact, these moments are just about the only time he ISN'T having sexual thoughts.
Achilles Heel: Possibly an angel's only weakness is removing the halo from above their head. (Unfortunately for Sakura, who does this several times, the edge is so sharp it cuts off the hand of anyone who forcefully grabs it.) It strips them of their power and gives them explosive diarrhea.
Zanzu even more so, to the degree that he is treated as a Butt Monkey by Sakura.
Calvinball: According to one episode, Dokuro likes to make up her own board games. The only one we see is the mystifying "Gothello". Hilariously, the special edition DVD set in Japan actually came with a Gothello set!
Celestial Bureaucracy: Heaven is portrayed as a bureaucracy that can only send increasingly ineffectual assassins after a young boy. Though this may be intentional. After all what better way to someone a lesson than to send people that would decide not to kill him yet essentially torture him for the rest of his life. One might say god knows exactly what he is doing.
The Chew Toy: Sakura. Also, Sabato, but to a lesser extent, as she's also frequently a flat-out Woobie.
Comedic Sociopathy: For someone trying to help Sakura, it almost feels like (permanent) death would be preferable.
Cute Bruiser: Zakuro, Dokuro and Sabato all match this trope.
Death Is Cheap: Sakura gets turned into gibs and resurrected all the time, and his strongest reaction is "That really hurt!".
Embarrassing First Name: "Sakura" is still considered pretty feminine in Japan, and in the Light Novels, Sakura actively laments his name.
Gainaxing: There's a bit of this every now and then. One instance is when Sakura accidentally pulls down Dokuro-chan's shirt, revealing her breasts, the nipples of which are covered by a conveniently-placed plant branch.
Getting Crap Past the Radar: Dokuro's cone-shaped cellphone that she keeps in her panties. Although the satellite that relays information to this show's radar is broken to begin with.
Groin Attack: The most cringeworthy is probably right in the opening, where Dokuro is seen leaning heavily on her spiked club, embedded deep in Sakura's groin. At another point in the opening she punts him in the crotch, sending him flying. Yeesh.
Magical Girlfriend: Deconstructed and parodied relentlessly. In the first episode of the anime, Dokuro talks about having studied various manga, including genre classic Urusei Yatsura, to get an idea of how she should behave.
Male Gaze: Again, Sakura. Used in the first episode when Dokuro-chan is flailing around on a table, and he states clearly that her panties are showing, which causes Dokuro-chan (who is trying to keep Sakura from working) to lift up her nightgown, giving Sakura (and the viewers) an incredible view of her panties and the undersides of her breasts.
Show Within a Show: Sensitive Salaryman Binkan, along with the accompanying Merchandise, a sausage that makes you extremely sensitive to every sensation. We probably don't want to know all of the implications of that.
Slasher Smile: Dokuro, Sabato, Sakura's classmates... anyone who is about to beat the crap out of Sakura.
Stock Footage: Subverted, in that while resurrection is done in a manner that looks like stock footage, it actually changes to accommodate what Dokuro is wearing at the time.
Stockholm Syndrome: A possible explanation for why Sakura resigns himself to putting up with Dokuro. The finale of season one is the best evidence.
Too Dumb to Live: Sakura, in spades. One would think he'd get a clue to stay away from Sabato the fourth time she tried to kill him in ten minutes. Or as soon as he saw the halo and horns, especially given Dokuro's record of killing him repeatedly. Considering how much he's died he just might not care that much anymore.
Weirdness Censor: Nobody but Sakura seems the slightest bit weirded out by Dokuro and her antics. When she turns one guy's head into that of a photorealistic howler monkey, the teacher shrugs it off as though it were normal and she had nothing to do with it. Sakura repeatedly lampshades this throughout the whole series whenever nobody takes any notice of something especially odd that Dokuro-chan has done.
"It can't be helped that the class representative has been turned into a monkey, so Dokuro-chan may sit next to Sakura-kun."
Wistful Amnesia: Even though there's really no reason for them to miss her.
With Friends Like These: The real reason Sakura's classmates waited for him before eating dinner was to find out if it would kill him. Sakura's classmates (sans Shizuki) are really only slightly better than Dokuro-chan, in that they only regularly abuse and demean him, instead of outright killing him.
Yandere: You bet your halo Dokuro's one of these. She interestingly exhibits qualities of a Tsundere as well. Dokuro's generally a "nice", "well-intentioned" girl, however she won't hesitate to become enraged and kill Sakura in two seconds. And then she's back to being dere-dere again.
Zettai Ryouiki: Dokuro has got to be at least a grade A, maybe even S. Just look.◊ High socks? Check. Twintails? Check. Tsundere? Do we even have to say it?
