This is a side story to Kingdom Hearts: Masters of Tomorrow

Your name is Plentiful Happiness, or Plen to your friends...well, if you had any.

Thanks to Sunset Shimmer, everyone in Canterlot High School, including your childhood friends, Applejack, Pinkie Pie, Fluttershy, Rainbow Dash, and Rarity, completely hates you. You've been battered, bruised, and beaten in more ways than one, until one day, you finally had enough. That was also the day you became one of the Keyblade's chosen...and changed your name to Empty Abyss.

With your mind clouded with vengeance, you abandoned everything and everyone, especially your own family, to pursue your own path to become stronger, strong enough to get back at the people who ruined your life.

After all, darkness always finds its way into a wounded heart...
