No-one has seen her face, everyone has seen her body. Kekko Kamen is a superheroine who apparently refused to wear the skin-tight bodystocking so it was removed from her uniform. She fights injustice, mostly focusing on rescuing students from insane disciplinarians.
!!The series and live-action films provide examples of:

* CallingYourAttacks
* DistractedByTheSexy
* FullFrontalAssault: This series is infamous for this trope and this trope alone. Kekko Kamen is never seen except in the nude -- wearing only a mask, boots, and shoes. (Her actual identity is a question that's never answered in the series.)
* GroinAttack: Inverted: Kekko Kamen uses her groin to finish off opponents with her "Open Thighs Jump" finisher.
** Well, it still can be described as GroinAttack; only as in "an attack WITH the groin" instead of "an attack TO the groin".
* HeyItsThatVoice: Creator/EmiShinohara is her voice and sings the theme, who is also recognizable as [[ProjectAKo B-ko]] and [[Anime/SailorMoon Sailor Jupiter]].
* InnocentFanserviceGirl: Kekko Kamen, of a particularly violent variant. In one of the live action adaptions / chapters of the manga, someone takes Kekko Kamen on a date. [[{{Fanservice}} She doesn't get dressed or act any differently.]]
* MaskPower
* MurderousThighs
* MusicalEpisode
* NamesToKnowInAnime: ''Kekko Kamen'' was created by GoNagai.
* {{Stripperiffic}}: A particularly extreme example of the trope.
* ShoutOut: The entire series is one big one to ''Series/MoonlightMask'' (=''G''ekko Kamen, geddit?), Japan's first tokusatsu hero. The theme song of Kekko Kamen is even a slightly rewritten version of "Who Is Moonlight Mask?"

!!The manga provides examples of:

* AffectionateParody: Kekko, her arch nemisis, Satan's Toenail, and every Villain of the Week are send-ups of popular Japanese manga and TV characters.
* [[spoiler:CollectiveIdentity]]: [[spoiler:In the last chapter of the manga, Kekko Kamen 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 BigBad and his minions, [[CrowningMomentOfAwesome in which all six sisters assume the mantle of the heroine at the same time and take them down]].]]
* CostumeCopycat: In one chapter, Kekko Kamen is framed by a naked masked woman (un)dressed like her who committs a robbery, and this leads the heroine to confront the woman to [[ClearMyName clear her name]].
* DefeatByModesty: The topless, jungle woman villainess Mako Makimura was defeated in this way after Kekko Kamen pulled off her loincloth, making her cover her privates. Then she was quite easy for the naked heroine to beat.
* {{Delinquents}}: Kei Kurenai
* IdentityImpersonator: [[spoiler:Mayumi]] tried to imitate Kekko Kamen after the twins who were thought to have been the naked heroine were captured. It didn't go too well, and she was unmasked and tortured as well until the real Kekko Kamen came to rescue all of them.
* TheLadette: Keiko Natsuwata, the short haired, masculine, P.E. teacher who knows all about martial arts and doesn't mind using them on people who try to hurt her or her students. She was actually thought to be Kekko Kamen for this reason.
* RememberTheNewGuy: One late issue had a girl described as Mayumi's best friend, despite not having previously appeared in the manga, being assisted by Kekko and Mayumi in escaping the oppresive school when she learns that her mother is ill with heart disease.
* SadistTeacher: The teachers of the Sparta Academy are particularly nasty examples of this, such as [[DisproportionateRetribution literally torturing students if they get anything below a 90 on their test's grade]]!
* SchoolNurse: Kaori Wakatsuki
* SweetPollyOliver: [[spoiler:Koichi Omote]]
* TheUnreveal: [[spoiler: At the end of the last chapter, the Kekko sisters confront a defeated Satan's Toenail and rip his mask off, revealing... that his face looks exactly like his mask.]]
