My name Yukasuna Agimoto. I was a normal eighteen year old who was moving into a new home with my parents, however on the day we had arrived the ponies appeared with goal of wiping out humanity and turning them into their kind. I was the only one who was unaffected as I woke up to see his planet being fused with Equestria. Now wielding strong unknown powers I plan to take back the planet that the Ponies had taken from me. However I am joined by a Pony, a Dragon, a Griffon, a Changeling, a Yak and a Hipogriff. Yup pretty crazy.
