History Manga / HighRiseInvasion

%%* MsFanservice: Yuri.
%%* NiceGirl: Yuri.

* SharpDressedMan: Sniper Mask, in a three-piece suit and tie, complete with a NiceHat.

* KnifeNut: Nise loves using small blades in combat.

Written by Tsuina Miura (initial writer of ''{{Manga/Ajin}}'') and illustrated by Takahiro Oba (Box!), ''High-Rise Invasion'' is a manga series with a heavy reliance on Fanservice and violence, with barely a chapter going by without either a PantyShot or [[YourHeadASplode someone's head exploding.]]

* AdultFear: It's not enough that an entity you couldn't see snatches up your kids and teens; they also send them onto a world full of killing machines. Or, even worse, they might even wind up becoming brainwashed killing machines themselves.

* BadassInDistress: Yuri and Nise get captured/surrounded by ngels.

* TookALevelInKindness: Nise loses the dark in her DarkActionGirl over time

* BeyondTheImpossible: Comes up once when Brother and Yuri talk about a mask's effect. The masks enhances your physical ability to a wildly improbable level, but not an ''impossible'' one. See RealityEnsues.

* ElevatorToSpace: The big building at the center of the world has changed: it's no longer the Rail Gun, it's now an orbital elevator, and it's believed that getting to its top will win the game.

High-school girl Yuri Honjo suddenly finds herself on the rooftop of a high-rise building. She's trapped in a bizarre world surrounded by skyscrapers, where a masked man cracked open a man's head with an axe before her eyes. Finding a way to survive this bizarre world, find her beloved brother, and escape becomes her top priority, but she is beset by danger not just from the mysterious Masks, which possess both inhuman strength and cruelty, but other survivors turned cruel or desperate by the insanity of the high-rise world.

* AntiVillain: Most of the masks are not evil people; they are just brainwashed into murdering non-masks.

* BadassInDistress: Yuri and Nise get captured/surrounded by masks.

* BrainwashedAndCrazy: The masks. Their masks make them so.

* EvolvingCredits: Any prominent Masks' true faces like Ein and Kusakabe that get revealed are shown in the opening credits.

* MoreDakka: The sad masks wield M-4s.

* PsychicAssistedSuicide: The fate of any mask who has their mask damaged to the point where they can't perform their duties.

** It's specifically stated by Brother that while the mask enhances your power to the limit of human physique, it will not alter your basic stamina. In a prolonged battle, the Mask who has the bigger body and/or wields the lighter weapon would eventually overpower the other mask. Nise uses this to her advantage when fighting Ain: She is a growing teenager wielding a combat knife while Ain is hardly an adolescent who wields a long Japanese katana.
** The Masks have to eat. So, they have to remove their masks. Also, if, say, the Masks sneeze, they are allowed to remove their masks for a short while to wipe the snot off their face. This also applies if they need to wash their face.
* SuspiciouslySpecificDenial: Aohara specifically mentions that he is only able to manipulate one mask at a time. Rika catches this right away and warns Yuri to beware of the second mask.

* WorldOfBadass: The masks enhance the physical abilities of anyone who wears them. Naturally, anyone who is able to stand up to them ''has'' to be a badass by default.

* GeniusBruiser: Brother Honjo knows ''everything.''
* GoodIsNotNice: Brother Honjo. A side character even explicitly says this.

* SelfDeprecation: Brother Honjo. Between complaining about his name, conceding that he has a twisted mind, and fearing about acting lame in front of his sister, the guy just takes it too seriously sometimes. In truth, all of his gripes are nonsense: He is as badass as they come.

* SuspiciouslySpecificDenial: Aohara specifically mentions that he is only able to manipulate one mask at a time. Brother Honjo catches this right away and warns Yuri to beware of the second mask.
* TakeALevelInBadass: Yuri becomes more combat cabable over time.

* ShoutOut: At one point, Yuri needs to create a password. She decides to go with a phrase from a series she watched a lot as a child. Although the words are changed, it's clear that the phrase is the incantation used in ''Manga/CardCaptorSakura'' for the titular character to summon her staff and even ends with her screaming "Release".

* NobodyPoops: Averted. Both Yuri and Nise are shown to using the bathroom. They become worried about this trope when they have to spend the night making camp on the roof. Since they are living in a state of emergency, they reason, they agree that if it comes down to it they'll just have to do it in the open.

An anime adaptation by Zero-G was released on Creator/{{Netflix}} is 2021.
