''Twinkle Saber Nova'' is an on-going {{manga}} by Creator/MiyabiFujieda, best known for the [[GirlsLove yuri]] gems ''Manga/TheMikosWordsAndTheWitchesIncantations'' and ''Manga/IonoTheFanatics''. Unlike said two works, ''TSN'' is a rather GenreSavvy {{shounen}} fighting comedy where lunches are SeriousBusiness and [[ImprobablyFemaleCast most characters]] are [[{{Moe}} adorable girls]]. It is, in fact, a remake of Fujieda's obscure debut doujinshi ''Twinkle Saber''.

The Misaki Academy High School, built on an island in the Tokyo Bay, is known for its ''laissez-faire'' approach to student activities. The pursuit of the students' freedom goes so far that even the most outlandish club activities are allowed. One of such clubs is the recently-established [[TakeOverTheWorld World Domination]] Club, that aims at nothing less than, well, [[ExactlyWhatItSaysOnTheTin taking over the world]]. However, since the world and even Misaki Academy are too big for them (yet), they decide to start small by taking over the Misaki Lunch Program and its associated restaurants first.

Enter our heroine, the high school sophomore Hayana Suzunari, who may be [[TheDitz not too bright]] but ''really'' [[BigEater loves her lunches]] and won't give them up to anyone without a fight. Unfortunately for her, the WDC has enlisted some of Misaki's strongest fighters to help them, but soon enough her teacher Kirise Fujishiro offers her a PoweredArmor suit, "Twinkle Saber", to combat the WDC in return for her joining Kirise's own club, the Ally of Justice Club (current membership: zero). Much to the surprise of Hayana's best friend Aoi, she agrees immediately and proceeds to kick the WDC's butts in a manner most awesome. Thus begins the story of two very strange clubs' rivalry...

WordOfGod (cited [[https://myanimelist.net/forum/?topicid=656153 here]]) is that this manga is set in the Fujiedaverse, but about 40 years after all other installments, like ''Amber Teahouse'' and ''Witch and Miko''.
!!The manga offers examples of following tropes:
%% Please add tropes related to individual characters to the character sheet rather than here in the main page.

* ImprobablyFemaleCast: Most of the recurring characters are female (or {{bishounen}}).
* InstantFanClub: Hayana gets hers by chapter one. They even have membership grades from Platinum (top ten members) to Bronze.
* KnifeOutline: Yagusae does it to immobilize the owner of a donut shop he is taking over in chapter four. Naturally, Hayana has something to say about that...
* LawOfChromaticSuperiority: The strongest Kyokusei of the present is awarded the title "Crimson".
* PoweredArmor:
** The Active Dress series, designed and built by Fujishiro-sensei, are the Ally of Justice trump card. So far, two have been introduced: Hayana's ''Twinkle Saber'' (001) and Satsuki's ''Arc Saber'' (002). There is also the SuperPrototype ''X-Trial'' series, of which only one, Kuon's ''Crymson'' (001), has ever been produced.
** The VSS series, apparently created by Aki Midou, is WDC's EvilCounterpart to Active Dress. So far, only two have been seen: Aki's own ''Priest'' and Sae's ''Silence'', but there may be more of them. VSS is an acronym but it has not yet been revealed what it stands for.
* RedBaron: All Kyokusei receive "colored" titles passed down from their respective previous holders.
* SchoolClubsAreSeriousBusiness: {{Invoked}} and {{lampshaded}}: The students can get away with literally anything (like trying to take over the school, or demolishing half of it in battles involving PoweredArmor), as long as it's a club activity. And to ''make'' it a club activity, they only need three members to register their "club".
* SchoolOfNoStudying: The Misaki Academy has very liberal student conduct requirements, which do not seem to include studying. Therefore, the students spend most of their time participating in various club activities.
* SeriousBusiness: Lunches. Between WDC starting the world conquest with them and Hayana's positively huge meals, this ''is'' pretty serious.
* TakeOverTheCity: Starting with the school
* TransformationSequence, subverted: From the dramatic way [[LargeHam Fujishiro-sensei]] introduces the Twinkle Saber, Hayana expects some flashy transformation to occur automatically. However, she just has to mundanely put the suit on like any other clothes. Cue [[DeadpanSnarker Aoi]] pointing out that [[MagicalGirl magic]] would have been more convenient.
* TwoTeacherSchool: Fujishiro is the only Misaki teacher introduced (or even mentioned) so far.
