High-Rise Invasion
Oshimeter
Synopsis
One moment she's a regular 16-year-old, and the next, Yuri Honjou suddenly wakes up in a world made entirely of skyscrapers connected by suspension bridges: no ground, no escape, no explanation. Oh, and there are masked figures with axes trying to kill everyone. Within minutes of arriving, she witnesses someone get their skull split open, and it only gets worse from there. Her one lifeline is learning that her brother Rika is somewhere in this nightmare too, so she sets out to find him while trying not to die in the process. The setting itself is what makes this ONA stand out: this maze of rooftops and bridges feels both wide open and suffocating at the same time, and you never know what's waiting on the next building over. The masked attackers aren't just mindless killers either; there's something deeper going on with them that the series slowly peels back, adding a genuine mystery layer underneath all the blood and chaos. If you liked the death-game tension of Darwin's Game or the brutal survival stakes of Btooom!, this hits a similar nerve. It also carries some of that same dark, disorienting energy as Gantz, where nothing quite makes sense and the violence feels deliberately uncomfortable. At 12 episodes on Netflix, it moves fast and doesn't waste time getting into the action. Fair warning though, the gore is not subtle, and the show leans into its horror elements hard. It's dark, it's messy, and it doesn't hold your hand.

wait so i was not entirely wrong all this time. they do have a connection damn. i knew he’s got to be someone. and yet another interesting angel. there’s too many characters to keep track of. also i kinda like the way Mayu is right now. apart from it being dangerous for her. but she’s damn strong though so i just like it. interesting plots but it’s getting a bit confusing now.
gurl why are you blushing hmm HAHAHA why am i invested in this little crush she has on the sniper lol but all in all, damn im loving Mayu more. she’s cool as hell. and this whole episode gives me headache. how many people are there that are closer to God? im so damn lost. and there’s just soooo many characters i can’t keep up.
that chef mask nearly made my heart jump out of my chest. what a way to encounter him bruh. i nearly died from shock seeing him appearing like that. anyway the game is making much more sense now. but the end goal is still kinda unclear. btw i’ve decided that sniper is my favourite character HAHA he’s kinda hilarious thoughhh. but Mayu was crazy for that. are we seeing a new partnership potential? a crazy one?
dude are u kidding me. My jaw is DROPPED. This show didn't end with a full conclusion. I thought, surely there's an episode 13 that I missed. NOPE. The creators made this show to promote their manga. 🥲 Well it WORKED because now with the biggest cliffhanger ever, I need to know what happens lmao. Otherwise, this was an amazing series and I'm so sad they didn't continue it. It was getting so good and we were so close to learning so much. They were great at teasing viewers 😭 This was such a strong show from beginning to end. also Sniper Mask + Kuon 4ever
Omg that beginning battle was INTENSE. Also Kuon and Sniper Mask are SO CUTE with their interactions omggg. Then the plot twist related to Uzuki !! The mask they're up against at the end is kind of silly LOL but I can't wait to see what happens.
Rika is so strong hahaha. I'm loving getting all this extra time learning about Sniper Mask, I am so intrigued by his storyline. LIKE LET US SEE HIS FACE ALREADY!! What an intense ending, too.
I'm loving this team that's being formed as the story progresses! Back to having lots of action throughout, and I have no idea what they're going to do after the cliffhanger at the end.
This episode mainly focuses on the main antagonist and his mission (which doesn't seem too intimidating), so lots more dialogue. Nothing was boring though, it was all interesting but it felt like it was all mainly setting the scene for what's to come.
There was quite a lot happening in this episode lol, I was worried it was going to fall off with the plot but thankfully that didn't happen. Nothing felt like filler or pointless battles. With the way it ended, it seems that the team is up against something strong.
This episode got SUPER tense, and Yuri's about to take a big leap to another level of her capabilities which is exciting. The timing of events at the end was so crazy lol such a coincidence.
Lots of more characters are coming into the picture now, and we're starting to learn their importance. It's interesting when more humans take over the scenarios than masks, there's still the aspect of having power and it makes you wonder the capabilities of those in this world. The scene toward the end was pretty funny too lol and I TOTALLY relate to Kuon fangirling over Sniper mask 😂
I am loving watching Mayuko and Yuri work together as a team, they have such great chemistry! This episode was filled with multiple different game-changing scenes and it has me HOOKED.
oh i guess i’m wrong…but Rika was still suspicious. how did he know all that. whatever he said to Yuri…bruh is damn savage as well. the way he kills ugh. and it’s possible to figure out the actual goal here. based on whatever’s happening in the end i guess it’s the highest level you get to reach if you survive long enough.
I think Yuri and Rika have a great sibling relationship together, I can't wait to see them fight side-by-side! The change-up to showing Rika's side was thrilling and all of the encounters make me wonder how they're going to get out safely. Definitely interesting ending in this one, too!
Mayuko is such a baddie! Her personality is so unique and I'm excited for her to be a part of the show. Once again lots of exciting action throughout the episode, and I'm enjoying learning about the secrets behind the masks.
A great ending to the series! The episode was filled with epic battle scenes and I like how each of the MC played a significant role in this episode.
Man the tension is high now! Seeing all the characters will eventually meet up in the final episode for the final battle made me so excited! Hopefully Rika and Yuri will manage to catch up in the next episode!
The start of the episode really got me on the edge of my seat during the interrogation. But seeing how composed Rika was made me so amused with his composure.
Love how this show just jumped straight into things! It feels intense and hearing all of Yuri's thoughts makes you feel like you're going through the emotions with her as she's processing everything. I can tell the action in this show is gonna be good! Can't wait to find out the mystery of the sniper mask, too.
So far the plot progress smoothly. It's great to see Sniper Mask also got his spotlight in this episode as well. Now the episode seems to have all the key characters in one place, I wonder what will happen.
