GANTZ:O

GANTZ:O (2016) is a Japanese sci-fi action anime you can watch online on iFILM. A teenager gets stabbed to death in a subway station, then wakes up alive in a sealed room — pulled back by a black sphere called Gantz.

The sphere drafts people at the moment they should have died, hands them combat suits and heavy weapons, and sends them to hunt aliens nobody else can see. This time the killing ground is Osaka, and the local squad runs on its own brutal rules. The creatures here are bigger and faster than anything the newcomer expected, and survival comes down to who reads the fight first. Yuki Kaji, Daisuke Ono and Saori Hayami lead the voice cast.

Directed by Yasu Kawamura and Keiichi Sato and built entirely in CGI off Hiroya Oku's manga, the film leans hard into close, weighty combat where a single wrong second is fatal. If you want your action grim, fast and short on mercy, this one delivers. Stream GANTZ:O (2016) online on iFILM.
