Dinaranger

An ongoing Hentai Super Sentai dark parody series set in a near-future Japan. The Zofa, a race of Rubber Forehead Alien invaders, have been besieging Earth for the past year, but are now losing ground as a result of the efforts of Dina, an organization specifically developed to combat the Zofa, and the DinaRangers, a team of three female super-soldiers enhanced with microchip implants and brightly-colored spandex suits.

The leader of the Zofa, frustrated with their recent string of defeats, entrusts the responsibility of bringing down the DinaRangers to his henchwoman Gunner, who has developed a sinister new method for converting humans to their side. By coating human females in Zofa cells, they become latex-skinned, mind-controlled slaves, capable of transforming others through sexual intercourse. This transformation process is so effective that not even the DinaRangers are immune...

Currently 16 chapters and two side-stories long, the author churns out a grand total of about 2-3 chapters a year, bundled together in a single release.

Tropes present in this work include

 * Abusive Parents: is a sadistic woman who takes great pleasure in her job, even going so far as to . But she wasn't always that way; as far as her daughter remembers, she used to be a kind and loving mother.
 * Action Girl: While the rest of the DinaRangers may be merely faux, Maya, the de facto leader, has consistently proven herself as a very capable fighter.
 * A Glass of Chianti: General Benin partakes of one at the end of Chapter 11.
 * Aliens Made Them Do It
 * Air Vent Passageway: Played unabashedly straight in Chapter 12. Chief Kamura decides to take the ventilation shafts to get to her objective without being detected.
 * Anatomically-Impossible Sex: Justified by the fact that the ZOFA cells make major changes to an infectee's biology. Whenever intercourse is shown, the parties involved are all either aliens, or humans in the late stages of infection.
 * Art Evolution: This has become especially conspicuous with the release of a Chapter 2 remake. The newer version contains more detailed people and backgrounds, and fewer anatomical goofs.
 * Being Good Sucks: In order for The Virus to be effective on the DinaRangers, the villains have to convince them of this.
 * Beware My Stinger Tail: Gunner can use her scorpion tail to tranquilize her enemies, or as a makeshift penis as part of the transformation process.
 * Big Bad: The enigmatic leader of the ZOFA.
 * Black and White Morality: Every member of ZOFA, every ZOFA Soldier, and every human secretly affiliated with ZOFA, is evil, plain and simple. Any characters who don't fall in the above categories are good.
 * By the Power of Grayskull: “DINA CHANGE!!!”
 * Calling Your Orgasms / The Immodest Orgasm: No Hentai would be complete without it. In this case it's Justified, as ZOFA cells are capable of pushing humans to pleasure "thousands of times greater" than a normal orgasm.:
 * Cannon Fodder: The beginning of Chapter 7 shows two of the villains discussing their decision to distract the DinaRangers with a scattered attack force composed entirely of ZOFA soldiers. It is implied that the DinaRangers had to kill them.
 * Chromatic Arrangement: Played with. The DinaRangers are color-coded by the three primary physical pigments, and the personalities that usually correspond to these colors are shifted around.
 * DinaRed, Ayase Maya, is the unofficial leader of the DinA Rangers, but has the typical blue personality, being the most uptight and serious of the trio.
 * DinaYellow, Fujiwara Miki, has the typical red personality, being the most combat-focused and emotionally driven.
 * From what little we've seen of her, the original DinaBlue, Uchihara Saori, had the typical yellow/green personality, being more quiet and reserved than Maya and Miki.
 * The current DinaBlue, Shiori, is more outspoken and easier to provoke than her sister Saori, but shares many of the same traits that make her more befitting of the yellow/green color.
 * Clothes Make the Maniac: Invoked by the ZOFA.
 * Compressed Hair: The ZOFA uniform is so tight that it manages to take the victim's long or poofy hairstyle, and compress it so tightly against her head that she appears bald.
 * The Corruption: The infection process is not unlike how Spider-Man's Venom invades its host.
 * Dangerous Forbidden Technique
 * A DinaRanger's SuperMode bestows incredible strength and agility for a short time. It also temporarily immobilizes her afterward.
 * General Sierra pops a strength-enhancing pill in order to keep up with . It's not long before she starts coughing up blood.
 * Death or Glory Attack: Maya attempts a downplayed one (a Defeat or Glory Attack) in Chapter 13, where she taps into her SuperMode, knowing full well that if she fails, she will lose the fight against General Ghana, and be utterly at her mercy.
 * Despotism Justifies the Means
 * Determinator: Really, Maya has absolutely no reason to believe that her mother is still alive, after having been taken from her by ZOFA five years ago. Yet it is her desire to rescue her mother that spurs her on for the majority of the series.
 * Deus Sex Machina: Narratively speaking, the four properties that ZOFA Cells need are a) a high infection success rate and high spreadability, b) the ability to make the body harder and stronger, c) a corruptive influence that induces psychological pleasure, and d) the power to reprogram the mind to induce total obedience. At no point is sexual intercourse necessary; in fact, some scenes show people being turned into ZOFA Soldiers without it.
 * Developing Doomed Characters: A case of this trope done right. The characters are actually sympathetic, and you feel bad for them when they're transformed into ZOFA soldiers and cruelly robbed of all of their characterization.
 * Dressed All in Rubber: ZOFA Soldiers.
 * Dutch Angle: The artist is fond of drawing scenes at conspicuously slanted angles, especially when things are going, or are about to go, south for our heroes.
 * Eldritch Location: ZOFA's Supervillain Lair, as seen at the very end of Chapter 4, is suitably sinister: A sleek outer wall; giant, haphazardly cut columns, several times the height of said wall, jutting out in every direction; chunks of floating rock scattered about; a cylindrical tower that stands above it all. And all of that is set in a strange, swirling void.
 * Empathic Weapon: The DinaSuits are implied to be this. The heroines' compatibility with their strength-enhancing suits is determined by their emotional state. If they get sufficiently enraged, they can access a SuperMode. If they suffer emotional distress, on the other hand, their suits become weaker, and in extreme circumstances,.
 * Evil Feels Good: As the victims of ZOFA cells will very loudly announce, repeatedly.
 * Exotic Equipment: See Beware My Stinger Tail above.
 * Face Framed in Shadow: In some appearances, the Great Leader is depicted this way. In others, his face is visible. It seems to flip-flop.
 * Face Heel Turn: Weaponized by the ZOFA.
 * Faceless Goons: Becoming a ZOFA soldier involves being turned into one of these. The bodysuit includes a skintight covering of the face and head which leaves only the eyes exposed, and only two soldiers thus far have displayed the ability to remove it willingly (for certain values of the word "willingly").
 * Fair Play Villain:
 * In Chapter 13, Ghana promises to call off the invasion of Dina Headquarters if Maya can resist the effects of the ZOFA Cells. One chapter-long session of humiliation later, when Maya still shows defiance, Ghana makes good on her promise, and leaves.
 * In Chapter 15, the Great Leader himself traps Maya and Miki in a room together, with the intention of letting them go if they manage to escape.
 * The Fettered: All of the DinaRangers fight for someone else. Maya fights to rescue her mother. Miki fights for the respect of her father. Saori and Shiori both fight to protect their family. These motivations are the source of their strength, as well as their emotional weak points.
 * Form-Fitting Wardrobe: Both the DinaRangers and the ZOFA Soldiers have these, though the ZOFA suits take it Up to Eleven- See Orifice Invasion below.
 * Four Eyes, Zero Soul:, once she becomes a ZOFA Soldier. (Apparently, ZOFA Cells make you inhumanly strong, but they don't fix your eyesight.)
 * Genre Blindness: Most of the heroes' failures can be attributed to the fact that they are not aware that they are starring in a pornographic doujinshi.
 * Genre Deconstruction: Of the Sentai genre.
 * Clothes Make the Superman: If you require a super suit to battle evil, the next time you lose access to your suit, you will learn the hard way that raw determination and a pistol will not make up for it. Not even close.
 * Heroic Willpower: It'll help you to resist the influence of Mind Control, but as long as the villains are keeping you on a short leash and deal with your resistance attempts as they come, it's not going to do you any good.
 * The Power of Friendship / The Power of Love: When your adversary's chief weapon is a virus that can brainwash people, your relationships can and will be used against you. You'll hold back against infected friends and family, and your impaired judgement will cause you to do risky things in order to save them, jeopardizing your mission in the process.
 * Sixth Ranger: A new recruit is going to be inexperienced and undisciplined, and as such will not provide nearly as much help against troublesome foes as a straight-up use of this trope would indicate.
 * Half-Human Hybrid turns out to be this, which leads into I Have No Daughter below.
 * Hermaphrodite: From Chapter 3 onward, ZOFA soldiers can become these at will (which is a lot).
 * The Hero: The red DinaRanger, Maya.
 * Heroic BSOD: In Chapter 13, when a certain revelation proves to be too much to handle,, is hit with a case of this. As a result of this emotional trauma,
 * Heroic Willpower: Deconstructed. Only those with the mental fortitude necessary can be DinaRangers, and there are only four known candidates who meet that requirement. Heroic Willpower is also the reason why it takes longer for a DinaRanger to be corrupted by ZOFA cells than most people.
 * High Concept: Sentai meets Zentai in a Hentai. Snappy, no?
 * Horned Humanoid: General Sierra has a giant facial horn sticking out from between her eyes, as well as another, slightly smaller horn protruding from the back of her head. She is the only ZOFA to have prominent non-human features.
 * Human Aliens: The ZOFA are an invading alien race, and aside from having unusual skin colors are indistinguishable from humans (with the exception of General Sierra; see above). It's even more pronounced in the black-and-white pages, where the only indication of a character's alignment is their manner of dress. (The ZOFA Generals, for instance, nearly always wear something that covers their eyes.)
 * I Have No Daughter: disowns their daughter in the beginning of Chapter 15.
 * Improbably-Female Cast
 * Industrialized Evil The ZOFA Cells were initially developed as a means of utterly breaking the DinaRangers, after they foiled ZOFA's plans one time too many. They quickly saw the utility of their new bio-weapon, and began using it as an easy and self-sustainable method of generating obedient foot soldiers.
 * Laser-Guided Amnesia: The ability of the ZOFA to control their brainwashed soldiers hinges on erasing their personality and their memories.
 * Lockdown: In Chapter 12, the Command Post at Dina undergoes one of these to protect themselves from the latest threat. Considering that Kamura escaped via air vent, the security of said lockdown is somewhat questionable.
 * Loss of Identity
 * Luke, I Am Your Father: Gunner was revealed to the audience to be Maya's mother back in Chapter 2, but for some reason this was treated as a secret until Maya herself discovered this in Chapter 9.
 * Made of Iron: ZOFA Soldiers are immune to physical pain.
 * Mad Scientist: Every ZOFA higher-up moonlights as one. Gunner continues to develop increasingly perverse methods to instill perfect obedience in the infectees, Benan developed the ZOFA cells to corrupt humans in the first place, and Shiera created a pocket dimension filled with aphrodisiac gas and Naughty Tentacles.
 * Magic Antidote: AntiZOFA (or Anti-Zofa Cells), which do Exactly What it Says on the Tin: remove ZOFA Cells and all their associated effects from an infected person. Though we never actually see it in action, it is used to cure one of the main characters. The effects seem to be instantaneous, and she is shown to have recovered both physically and mentally.
 * Magic Skirt Played straight. Yes, you read that right. Despite how most of the female characters wear short(ish) skirts, the artist almost never resorts to Panty Shots.
 * Memory Gambit: performed this on themselves to flawlessly hide among the ranks of Dina until a certain event triggered their memories to re-emerge.
 * Mildly Military: Dina, being a combined civilian/military organization, is this. On several occasions, the Rangers will talk back to their commanding officers, who never seem to exercise their authority.
 * Mind Manipulation
 * Brainwashed
 * Brainwashed and Crazy: ZOFA soldiers are willing to attack and transform their former friends and allies.
 * Getting Smilies Painted on Your Soul: Of the 'purely sexualized variety.
 * More Than Mind Control: While vanilla brainwashing is sufficient to turn most people into ZOFA Soldiers, when the Dina Rangers are infected by The Virus, they need to be convinced that putting their lives on the line to save the Earth isn't really all it's cracked up to be. In Chapter 8, despite Miki's best efforts to resist being turned into a ZOFA soldier, she eventually faints. At this point, an illusion of the Big Bad invades her subconscious and attacks her emotional weak points, causing her mind to crumble and allowing the ZOFA programming to take hold.
 * Not Brainwashed: After an attempt to cure her of the influence of ZOFA Cells fails, reveals that she was working for ZOFA of her own free will all along.
 * The Mole: is revealed to be this at the end of Chapter 11.
 * Naughty Tentacles: Featured in the second half of Chapter 7 and the entirety of Chapter 8.
 * Nepotism: Fujiwara Miki's backstory is centered around how, being the daughter of the Commander, she was promoted through the ranks of Dina, despite not being as skilled as more deserving people. This had earned her the ire of her peers. It was only after she was singled out as a Dina Ranger candidate that she was able to prove her worth to those around her. But some people, like Saejima Emika, continued to hold a grudge against her.
 * Organic Technology: The ZOFA cells.
 * Orifice Invasion: But of course. When the ZOFA cells cover a human, they also enter through her ears, mouth, and various other holes.
 * Parental Betrayal
 * Although it was revealed to the audience much earlier, in Chapter 9.
 * A second instance occurs in Chapter 15, this time.
 * Plot With Porn: Leaning towards a 50-50 split. The appeal of the series is very dependent on the porn aspect, but the plot only serves to up the Fetish Fuel and Nightmare Fuel aspects of said porn.
 * Pocket Dimension: One features prominently in chapters 7 through 9.
 * Rape Is Love: Invoked by the ZOFA. The process of becoming a ZOFA soldier almost always involves being infected and raped by another ZOFA soldier. The ZOFA cells infiltrate the victim's mind and brainwash her into enjoying it.
 * The Resenter:
 * Emika, for the longest time, held a grudge against Miki. While Emika had to study hard to make it to her high position in Dina's command center, Miki was given a position alongside her because she was the Commander's daughter. Later, Miki was discovered to be one of the few compatible with a Dina Suit. Emika greatly resented Miki's unbelievably good fortune... until Chapter 10, where she concludes that her negative attitude caused Miki to come back incapacitated, and decides to turn over a new leaf.
 * And on the ZOFA side, Ghana resents Benin for having been selected as the Great Leader's number two. Benin was the one who engineered the Zofa Cell, but Ghana was the one who researched and developed methods for infecting and transforming humans into ZOFA Soldiers. Ghana firmly believes that her contributions far outweigh Benin's, and feels she deserves the promotion more. It certainly doesn't help matters that Benin clearly enjoys rubbing her success in Ghana's face. The end result of all this is that Ghana puts all her time and energy into developing more and more advanced systems of brainwashing, in order to prove her worth to the Great Leader and show Benin up. This gives us a rare case of a villain in a hentai work that has motivations beyond such stock cliches as petty revenge or world domination.
 * Romance Genre Heroines
 * Red DinaRanger Maya is The Crusader. This is best exemplified by her unwillingness to back down even if it means fighting her own mother.
 * Yellow DinaRanger Miki is The Boss, although Maya is the de facto leader of the group. She desperately wants to prove that she deserves her position, especially to Emika.
 * The first Blue DinaRanger Saori, in much of her "posthumous" characterization, is often depicted as The Nurturer, wanting to preserve the security and happiness of her mother and sister above all else.
 * Her successor and sister Shiori is The Spunky Kid. The fact that she agrees to take Saori's place despite knowing of the danger shows her pluck, and she is shown to be sufficiently spirited when she finally goes toe-to-toe with a General and holds her ground despite her inexperience.
 * Rubber Forehead Aliens: ZOFA have odd skin colors, and a scorpion-like tail in Gunner's case, but are otherwise indistinguishable from humans. In the black and white pages, a ZOFA's skin isn't even shaded differently from a human's skin. Considering Ghana's true identity, however, there might be a reason for such similarity between the two races.
 * Sensual Spandex: The DinaRangers' uniforms are this. Aside from the fact that their nipples are often visible, the suits are still fairly respectably designed. Doubly so compared to what ZOFA Soldiers wear.
 * Shy Blue-Haired Girl: Saori, from what little we see of her; her sister Shiori is much less so.
 * Significant Green-Eyed Redhead: Maya.
 * Spell My Name with an "S": The transliterated title is "dainarenja," so the proper translation of the series name should be DynaRanger, not DinaRanger. Unfortunately, the author himself translates it as DinaRanger in the title logo, so the superheroines are referred to in the translations as DinaRangers for consistency.
 * Super Mode: is the first DinaRanger to ever unleash SG Mode, as evidenced by mission control's reactions. Unfortunately, it also turns out to be a Dangerous Forbidden Technique (see above).
 * Survivor Guilt: When Miki is brought back comatose in Chapter 10, her rival Emika feels that what happened to Miki was all her fault.
 * Take Over the World: The Great Leader's goal is to take over the Earth. He doesn't seem to have any real motivation for it, though.
 * Talking Is a Free Action: Played straight most of the time, but notably subverted and lampshaded by the Great Leader in Chapter 15; after he explains his evil plan to a DinaRanger, he mocks her for just standing around and listening instead of taking action.
 * Techno Babble: Present in unusually high quantity for a pornographic work. Nearly the entirety of Chapters 10 and 11 are dedicated to expository dialogue explaining the technical details behind the ZOFA soldier transformation process... although you probably won't be paying attention to the stuff in Chapter 11.
 * Theme Naming: The ZOFA Generals are named after equatorial African nations: Ghana, Benin, and Sierra (Leone).
 * Tomato in the Mirror: In Chapter 15, wakes up, seemingly human, with memories of having been recently corrupted by the ZOFA Cells. She assumes that someone must have given her the Magic Antidote at the last minute. Over the course of the chapter, she starts to realize that something's wrong with her, but she's not prepared to accept the most obvious reason... until she looks at her own reflection.
 * Transformation Trinket: The bracelets that the DinaRangers wear while in civilian clothing. If one of these shatters, it's a clear sign that things are going horribly, horribly wrong.
 * True Companions: In Chapter 16, Miki has a flashback to the formation of her original Nakama (back when Saori was on the team). She remembers how happy she was to be part of something greater than herself, and how being a DinaRanger saved her from being a shallow and self-absorbed shell of a person.
 * Twenty Minutes Into the Future: Future Japan hardly seems more technologically advanced than present-day Japan, except for the DinaRanger technology.
 * Unspoken Plan Guarantee: Inverted; in Chapter 12, when the heroes draw up a plan to fend off ZOFA's invasion force, the reader is privy to all the details. As a result, it all goes wrong.
 * The Virus: ZOFA cells. And it's sexually-transmitted, to boot!
 * White-Haired Pretty Girl: Saejima Emika is shown to be this on the cover of Chapters 9-11. Interestingly, in the black-and-white pages of the comic, her hair is a much darker shade.
 * You Gotta Have Blue Hair:Of the ten characters with confirmed hair colors, the only ones with realistic hair colors are Miki (reddish brown) and her father (dark brown).
 * ZOFA Apocalypse: The apparent ultimate goal of the Zofa is to turn all humans into mindless slaves.
