Equestria has fallen on the darkest hour it has ever faced. The Elements of Harmony have expended their power from constant and frequent use, and only one hero who was summoned across time and space can save them. The fate of the world rests on the shoulders of the strongest man and his disciple.

Characters based off MLP FiM and also from Onepunch Man by ONE. (I heavily recommend giving the manga a look, though you will most likely want to check out the issues that were redrawn by Murata Yuusuke.)

After years of learning her new powers and growing into being an Alicorn, Twilight Sparkle has reached maturity. Her loving mentor Celestia feels she is now ready for the ultimate test, to succeed where her sister and herself failed. Celestia reveals the origin of her sister and herself, and tasks Twilight Sparkle to travel across the great sea and take the throne in the land that they were exiled from.

Three friends who have fought together countless times have decided to retire from their lives as adventurers. They return to their home city and take up local jobs, they have lived this way for half a decade now. But their retirement from their youthful ways of adventuring is put to an end when they are tasked with a new goal from their leader, to find a cure for their people.
