Over a year ago, Twilight Sparkle, Discord and four million other ponies escaped from an alternate Equestria on the verge of collapse, hoping to start a new life on Earth. If only all humans were as open to ponies as most.
Some things never change: He's still the number one most unpredictable and knucklehead on the planet. The fact that he's now the Mad God Discord and doesn't remember being Naruto the Savior didn't change that. Twilight just had to make him remember.
Twilight discovers she is an old soul, having lived many times yet getting further and improving the world each time. Now an alicorn, she has new options to explore: including remembering, but at a cost. Luckily, Discord is there to help her.
Barely even friends, then somebody bends, unexpectedly - just a little change, small to say the least: both a little scared, neither one prepared... beauty and the beast.
