Steins;Gate: Burdened Domain of Déjà vu
This was really really good. I didn't really know what they could even do with a sequel to this story but they did it anyways because that's what mad scientists do. Like it was shockingly amazing and good. It's hard for me to express just how good this was but it was really good. As a coda and epilogue for something, this has to be one of the best I've ever seen. That's how good it was.
