From the article:
While only Episode 1 has been officially released, all 12 episodes have appeared on unauthorized torrent sites. The material appears to be finalized, including full animation and audio, though the source of the leak remains unknown.
One of the circulating torrent file descriptions includes a link to a Japanese streaming site, happydouga.jp, though its connection to the leak is unverified and may have been falsely added by the uploader.
Expect more ACE takedowns… seriously it’s not worth it hosting these leaks… You’ll get the entire site deep sixed
Remember how many websites died because of ReZero leaks?
