Where Can I Find The Best High Rise Invasion Fanfiction Stories?

I’ve read a decent chunk of 'High-Rise Invasion' fanfic, and honestly, it often feels more like a character study than a straight survival thriller. The original manga/show gives you this insane premise—trapped on rooftops with masked killers—but the survival elements can get a bit repetitive: find a weapon, don’t fall, outrun the next bad guy. Fanfiction writers seem to latch onto the psychological isolation more than anything else. They’ll take a character like Yuri, who’s already pretty resilient, and put her in a scenario where the real threat isn’t an axe-wielding mask, but the slow erosion of her sanity from the endless quiet between skyscrapers. Some fics ditch the constant action entirely. I read one that was basically a series of diary entries from a background character, just documenting the dwindling food supply in a server room and the paranoia setting in among the survivors. The ‘unique’ part is that the environment itself is the trap; you can’t go down, you can barely go sideways. It flips survival from being about brute force to being about resource management in a vertical, utterly unnatural landscape. The fear isn’t just of death, but of making a choice that leaves you with no path forward at all, literally. That specific kind of claustrophobia, with the whole sky open above you but every direction a potential dead end, is something I haven’t seen explored quite the same way elsewhere.

crossovers with original characters from other series are definitely a thing, though they can be hit or miss. The survival game structure makes it a natural magnet for crossovers—characters from other brutal settings get thrown onto the rooftops and have to navigate the masks and rules. I remember one that stuck with me was a crossover with 'Danganronpa,' where a few of the ultimate students ended up in the high-rise world. The author really played with the clash of philosophies: Danganronpa's manufactured despair versus the more visceral, chaotic horror of the masks. It worked because the characters' existing trauma informed how they reacted to the new threats, rather than just making them overpowered. Another decent one blended elements from 'Alice in Borderland,' focusing on the puzzle-solving aspect under extreme pressure. Most of what I find tends to be on Archive of Our Own or FanFiction.net, tagged with both 'High-Rise Invasion' and the other series. The key for a good read, in my opinion, is whether the writer respects the tone of both sources. Too often, an OC from a shonen anime just muscles through everything, which kills the tension that makes 'High-Rise Invasion' compelling in the first place. I tend to filter for 'gen' or 'action/adventure' to find these plot-heavy mixes. Some authors create original characters that are essentially archetypes from other genres—like a hardened detective from a noir story or a survivalist from a post-apocalyptic tale—and insert them. Those can be fun experiments in genre collision, seeing how a cynical, gun-toting type deals with the absurdity of the mask enemies.

Seriously, anyone else notice how 'High-Rise Invasion' fanfic dynamics get stuck in a loop? Most writers latch onto the core survival tension between Yuri and Sniper Mask, which makes sense—that predator/prey, hunter/hunted dynamic is baked into the source. But I feel like so many stories just turn that into a generic protective guy/competent girl romance, flattening all the weird, frantic panic of the manga. The setting's this surreal death game on rooftops, but the fanfiction often feels like it's happening on solid ground. I crave fics that really lean into the verticality and isolation. Like, a relationship built on literally having each other's backs while dangling off a ledge, where trust isn't emotional but a physical necessity for the next jump. The few I've found that explore Mayuko and the mask-maker's messed-up devotion, or even platonic bonds between random survivors who know they might have to kill each other tomorrow, hit way harder for me. The mainstream ship stuff can be fun, sure, but it often misses the unique, paranoid flavor of the original.
