Steins;Gate: Fuka Ryōiki no Déjà vu is to Steins;Gate what Burial at Sea is to Bioshock: Infinite. It’s the bit extra for those that really like the franchise. That final piece of story that exists despite the fact that the original narrative has been fully concluded. And, of course, it only exists thanks to some haphazard use of parallel universes. You thought Steins;Gate was over? Well now the main character keeps jumping onto a different world line for no reason, and it’s not really over till this stops happening.
