Boy: "There's no way this heavily modified Unlimited Blade Works is my fault! Why do I have to collect the weapons myself and put them in there? Why won't it activate even though I have enough mana? Why does a shut-in like me have to become a hero of justice? This has to be the author's fault!"
In short, it's the story of a shut-in who gets lucky and becomes a planeswalker, learns Unlimited Blade Works, Projection Magecraft, and Reinforcement Magecraft from the Red Dog, then goes around the various worlds showing off... Ahem... saving the world (and girls). (Stern face.)
