The visuals in the background looks beautiful (meaning Toei isn’t in charge of this).
Sadly, not KyoAni either because you can tell they like to make everything in the animation, beautiful, but the animation was a bit plain to be them.
My bet is on 8-Bit or P.A. Works.
8-Bit because you can kinda tell similar animation styles from Comet Lucifer and the PV.
P.A. Works because they need something to save them from Charlotte.
Wasn’t there something like “SF” in the preview ?
April 1st is always a big day for Key.
I doubt that this was fake. No one would waste money for animating something just for a joke.
