History Manga / MyMonsterSecret

** Firstly we have the tale of Princess Kaguya [[RecycledInSpace in Space]], which is clearly an analogue for Aizawa's experiences over the course of the series. [[spoiler:Later on it's subverted: the play was actually written by Future Aizawa, who then sent it to her past self with fake orders from the home planet to submit it for the class play.]]

*** And as to why the spaceships are there...[[spoiler:Nagisa's home planet invaded Earth after being unable to peacefully coexist with humanity; Nagisa blames herself for being unable to mediate between the two worlds. Though in chapter 163 it was revealed she made the whole story up, and in her actual future her planet was able to make peaceful contact with Earth.]]

* BlackComedyRape: One of the series's running gags:

* WatchThePaintJob: Akari is very proud of her brand new car, Sure enough, when Akane ends up driving it (or rather, levitating it with her powers) it gets ruined.

* WithFriendsLikeThese: After [[spoiler:Aizawa confesses to Kuromine then accidentally kisses him in public]] and rumors start circulating that they're going out, Okada and Shimada spread rumors that shift the blame off of her. Of course, the rumor they spread is that he's a scumbag abusing all the girls around him for money. It doesn't help that [[GentleGiant Sakurada]] [[BewareTheNiceOnes takes all of the rumors at face value]], or that Mikan, Shiho, Rin, and [[{{Troll}} Akane]] all [[BeAsUnhelpfulAsPossible roll with the rumors and help propogate them]]. Akari [[WhatTheHellHero pulls them all aside and lectures them]] about how, [[FairWeatherFriend instead of supporting him in his time of need, all his friends basically turned on him]] and ruined his reputation.

* BlackComedyRape: THRICE.

* DamnedByFaintPraise: In Chapter 155, the class is choosing a play to perform for the school festival. One play, which is obviously Youko's, is so bad[=/=]cheesy that it looks like it's physically painful to read (except Miss Ryokuenzawa, who calls it a masterpiece). Thankfully, Akari comes in and says "Like...you know...the penmanship is nice." The rest of the class seizes on that, and thankfully Youko buys it.

%%* EarWorm: The Magical Akalyn theme song is regarded as this.

* IKnowYoureInThereSomewhereFight: Sort of played straight and sort of parodied in the [[spoiler:Sakurada vs. Akari arc, where the latter has lost her mind]], around chapter 140. It's played straight in the sense that the stakes of the "fight" are real, but this being Jitsu wa, the way the fight unfolds is… rather silly. [[spoiler:It invoves an epic and dramatic… tricycle race, and other normally mundane sports fest events.]] The characters' expressions are still 100% serious, mind you.

** Chater 75 had a weather phenomenon where the weather would get worse when someone is being out-of-character (Youko acting like an actual cool beauty, for example). When ''Akane'' starts being nice, it almost resulted in TheEndOfTheWorldAsWeKnowIt.

* [[invoked]]RealitySubtext: In Chapter 162, [[spoiler:Aizawa's "Space Princess Kaguya" play is underscored by the fact that, like Kaguya, she's leaving Earth to return to her home planet. At this point the cast pretty much abandons all pretense and everyone says their goodbyes right then and there, not even bothering to use their characters' names anymore.]]

** Shimada being arrested after doing perverted stuff, by a surprisingly prompt police officer (it starts in chapter 18 as a FunnyBackgroundEvent, but it doesn't become a recurring gag until chapter 81). This one is so persistent it actually continues (as a background cameo) [[Manga/ShuukanShounenHachi in Masuda's next series]], and then into the one after that ''Manga/YumemigaokaWonderland''.

* VitriolicBestBuds: Youko and Akane can't spend a minute together without bickering, but they still spend a lot of minutes together. Mikan and Okada also have shades of this, with the latter ofter teasing her as if waiting for her retaliation. And then there's the "rivalry" between Shiho the pervert and Rin the pervert-hunter.

** In episode 2 of the anime, when Nagisa explains that she read the function of the [[DropTheHammer "memory erasing device"]] in a manga, we briefly see a page of ''Sakura Discord'' where a character uses a HyperspaceMallet.
