All of Us Are Dead season 2 moves beyond Hyosan High: What Netflix confirms about On-jo, returning stars and new faces

Netflix names Park Ji-hu, Yoon Chan-young, Cho Yi-hyun and Lomon as returning cast members. They play On-jo, Cheong-san, Nam-ra and Su-hyeok. Their return is confirmed, although the announcement does not reveal every detail of their character arcs.

Netflix’s official season-two synopsis follows Nam On-jo as a university student in Seoul, still affected by the Hyosan disaster. A new city outbreak pushes the story beyond the high school that defined the first season.

Roh Jae-won joins as Han Doo-seok, a National Intelligence Service team leader. That is a confirmed character description from Netflix; it does not establish the character’s loyalties, fate or a particular explanation for the new outbreak.

Lee Min-jae, Kim Si-eun and Yoon Ga-i play Yong Ma-ru, So Ju-ran and Lee Jong-ah. Netflix places these new university friends alongside On-jo as they face the next outbreak, widening the group of characters caught in danger.

The Economic Times reported on October 20 that filming has finished and post-production is underway. That updates the production stage described in Netflix’s older cast announcement, which was published when filming began in July 2025.

The same current report discusses an early-2027 release but says Netflix has not confirmed a date. Season one remains on Netflix. Treat a month circulated online as an expectation until the platform announces the actual season-two premiere.
