In the midst of the night, a lonely Alicorn Princess stares sorrowfully towards the star-lit sky on the balcony, wondering what the future will hold in the nearly one thousand years since her sister's banishment. But as she ponders, a small unknown object comes spiraling down.
With little else to do, Celestia flies towards the landing site, only to discover a tiny little creature with a monkey tail, a saiyan, sleeping peacefully in a metallic pod. In her motherly instinct, alongside a desire to ease her loneliness, Celestia radically adopts this boy called Kiryu.
But, the thousand year mark is growing near, darkness begins to creep up from the shadows, enemies both domestic and foreign look wanting towards Equestria. This is the beginning of a new tale, a story about how a small kind boy becomes the greatest Defender of Equestria in history, along with the help of new friends and allies!
