William, is not your ordinary highschooler, he is introverted, quiet, a tad bit impatient, and has an obsession with firearms that others would consider downright creepy, he also happens to have a closet obsession with My Little Pony. One day after going to a sleepover he is brought to Equestria by Griffon, Dragon and Changeling mages and given the ability to summon any piece of military hardware he so wishes in hopes that he would lead them to victory against the ponies of Equestria. He is happy, but when he discovers their attempt to deceive him...

Ok, well... It really wasn't deceiving. Because they never told him who they wanted him to go up against. But regardless!....
