Kekko Kamen

Kekko Kamen (けっこう仮面, Kekkō Kamen?, sometimes romanized as Kekkou Kamen, Kekko Masked, Mask of Kekkou or Mask the Kekkou, and translated as Splendid Mask) is originally a shōnen manga series from Japanese creator Go Nagai, which spawned an OVA series and several live-action films. The manga series is about the misadventures of a student named Mayumi Takahashi who attends a boarding school called Toenail of Satan's Spartan Institute of Higher Education that is run by sexual predators. The teachers are constantly looking for ways to torture or humiliate the students, and from this the teachers derive sexual satisfaction. Takahashi's only protection is from a mysterious figure known as Kekko Kamen.

Plot
The main character lurks around a corrupt, misogynistic "high education" high school called the Sparta Academy (スパルタ学園, suparuta gakuen?), where the penalty for any student (usually girls) making the slightest mistake is being sexually humiliated by the perverted teachers running the school, the mastermind being a demonic, jester -like villain named "Toenail of Satan". Before the teachers take their sexual advances too far, Kekko Kamen breaks in and beats up the bad guy before performing a finishing attack by jumping into the air and landing crotch-first onto the opponent's face. In the anime, the impact causes him to lose consciousness. Sprawled unconscious on the floor, the villain usually has a smile on his face. In the manga, Kekko Kamen often kills the villains with her crotch attack, or with a hit from her nunchaku.

Characters
A mostly nude female superhero dressed only in a red, rabbit-eared mask, with matching gloves, scarf, and boots. She uses her body to distract the usually male enemy teacher that she fights in order to protect the young student Mayumi Takahashi. She fights with a graceful and acrobatic martial arts style, as well as often using weapons to aid her, such as nunchaku and a bo staff. Kekko Kamen's finishing move, the Pubic Hair Jump (おっぴろげジャンプ - Oh Piroge Jump), involves her leaping into the air and spreading her legs, distracting her enemy with her groin, and crashing into his face. The impact and distraction causes him to lose consciousness. Many young women get suspected of being the heroine. In the last chapter of the manga, she is revealed to be six sisters who have been among the students and teachers, taking the role in shifts to avoid suspicion. This all culminates in a final battle with the evil principal and his minions, in which all six sisters assume the mantle of the heroine at the same time and take them down. A young, first year student at the Sparta Academy. Mayumi is an innocent and good natured, yet somewhat dimwitted girl, whose bad grades often land her in the school's torture chamber, where she is subjected to humiliating punishments. However, before the teachers are about to completely violate her, Kekko Kamen always manages to burst in and save the day. Her hero's constant rescuing of her has filled Mayumi with a deep amount of affection for her, and she often wonders whom the masked heroine could really be. The main villain, the wicked principal of the Academy, who dresses in a fearsome white demon mask and jester hood. He is extremely perverted and obtains satisfaction from sexually humiliating the female student body, especially Mayumi Takahashi. This often brings him into conflict with Kekko Kamen, whose secret identity he wishes to uncover. To accomplish this, he brings out various punishment councillors to publicly humiliate Takahashi, using her as bait to bring the naked warrior of justice out in the open. However, he always manages to be defeated by her. He also appears in Maboroshi Panty, as well. A shy, introverted second year student. After Mayumi sees her bare body during a plan to catch Kekko Kamen, she believes that this girl is in fact her hero. However, what Mayumi and the rest of the school doesn't know Chigusa is actually hiding a different secret: she is actually twins named Chigusa and Yuka, who mysteriously enrolled in the school under the identity of one student. The tough, masculine Physical Education teacher who is an expert at various styles of fighting techniques, sports, and with many types of weapons. For this reason, the principal suspected that she was actually Kekko Kamen, and began to humiliate her. This theory was disregarded when Kekko Kamen jumped in to rescue her. A supposedly first year male student, who is in the same class as Mayumi. However, another student uncovered that he was actually a female in disguise. This prompted the Principal to believe that she was Kekko Kamen. When her true gender was unveiled, Keiko suddenly rushed in to save her, and confessed that she was Koichi's older sister. Both sisters were then captured and tortured until Kekko Kamen came to their rescue. After this revelation, Koichi continues to be a valuable friend and ally to Mayumi. A young student who is positively infatuated with Kekko Kamen, and is inspired to become a heroine of justice herself. So, armed with a rapier, she becomes the mostly nude, caped, swashbuckling hero with a ribbon covering her crotch known as Ribbon no Shishi (リボンの獅子). However, on her first attempt to combat the evil of the school, Ai finds herself in danger. Fortunately, Kekko Kamen comes to her rescue. After this incident, Ai continued to appear sporadically throughout the manga as a supporting character. The very attractive school nurse. After Kekko Kamen's thigh is injured in a battle, the villain traces her to the infirmary, and confronts Kaori, ripping off her clothing in an attempt to find the scar, only to realize it wasn't there. Kekko then appeared with a bandage on and rescued her. A red-haired, chain smoking, tough as nails third year student and gang leader. But beneath her brash exterior, she may be concealing something. A perverted, insane, abusive, sadistic, mad scientist teacher who works for Toenail of Satan. He always punishes Mayumi Takahashi for failing on her grades and always gets defeated by Kekko Kamen.

Production
Kekko Kamen is a female superhero whose costume consists solely of red boots, gloves, scarf and a mask with long bunny-like ears. Her fighting style is graceful, and her finishing move involves driving the opponent to the ground with a flying headscissors takedown which presses her groin into the victim's face. While regularly considered as a hentai series, it doesn't have many explicit sexual situations, neither in the manga, anime or live-action series, though there is abundant female nudity in all of them.

Kekko Kamen is a parody of Gekko Kamen. It was originally a joke that Nagai sent to his editor expecting him to reject it. His editor, however, loved the idea and that started Kekko Kamen. As well as the similarity in name, both Kekko Kamens and Gekko Kamens true identity is never revealed. Even the name of the main antagonist is a parody: in Gekko Kamen it's Claw of Satan (サタンの爪<span class="t_nihongo_comma" style="display: none;">, Satan no Tsume<span class="t_nihongo_icon" style="font: bold 80%/normal sans-serif; padding: 0px 0.1em; color: rgb(0, 0, 238); text-decoration: none; font-size-adjust: none; font-stretch: normal;">?) while in Kekko Kamen it's Toenail of Satan (サタンの足の爪<span class="t_nihongo_comma" style="display: none;">, Satan no Ashi no Tsume<span class="t_nihongo_icon" style="font: bold 80%/normal sans-serif; padding: 0px 0.1em; color: rgb(0, 0, 238); text-decoration: none; font-size-adjust: none; font-stretch: normal;">?).

Ten live-action films have been made of Kekko Kamen, along with one OVA series. A photobook has also been made, featuring a martial artist as Kekko Kamen. A sequel photobook featuring Kekko Kamen's daughter, Kurenai Kamen, has also been made.

The theme song for Kekko Kamen (used in anime and tokusatsu adaptations as well as the original manga) uses the same lyrics for the theme song to Moonlight Mask, but with changes.
