Talk:Rio (game)/@comment-26231946-20151005053312/@comment-26841482-20151005055029

As Highermind said, "There's an ending where Rio dies and Kaneki survives."

Kaneki is alive in :re, so I guess that the manga was mirroring the game and Rio does not exist in :re.

As for how he died? I don't know. Suicide, maybe?
