Yes, you read that correctly. The stream announced that the series spawned by Final Fantasy VII Remake back in 2020 is a trilogy consisting of three games, of which Rebirth is the second volume. The Twin Towers to The Lord of the Rings, suffice to say. Or, as the credits in Remake stated, this marks the continuation of "the Unknown Journey", where...okay, if anyone has yet to play Final Fantasy VII Remake to its conclusion, I suggest you do so, as it carries enormously heavy implications and realities for what the rest of the trilogy will be exploring.
For now, enjoy watching Cloud and Sephiroth having a leisurely stroll towards what is presumably the Nibelheim Mako Reactor at Mt. Nibel, just on the outskirts of Cloud's and Tifa's hometown, Nibelheim.
