High-Rise Invasion (Season 1)

High-Rise Invasion (2021) is a Japanese Netflix anime you can watch online on iFILM. Schoolgirl Yuri wakes on the roof of a skyscraper just in time to watch a masked figure split a man's skull with an axe. Every exit is sealed. All that's left are the catwalks between towers and the killers who patrol them.

The logic here is brutal and plain. The Masks rarely finish you off themselves — they push their victims toward despair until they jump on their own. Yuri sets out to survive and find her brother Rika, trapped somewhere in the same nightmare. Along the way she meets other survivors, some willing to team up, others as unhinged as the executioners chasing them.

Based on the manga by Tsuina Miura and Takahiro Oba, the first season runs twelve episodes. It's a fast, bloody survival thriller with simple rules and rising momentum — built for fans of battle-royale setups and grim action anime that doesn't waste time.
