Friendship, love, fights, and fireballs: never cross swords without being introduced first!

They are three: a magician princess, a formidable fencer, and a brilliant tinkerer. They don't know each other and they don't like each other, but they must put aside their differences to save the world. Fights, betrayals, explosions, budding love affairs, and fratricidal rivalries—they'll witness all of these. And then, there is... him. The man who doesn't know how to do anything, doesn't understand anything, and has somehow wound up in the middle of this story. But he's nice. That's something, at least!
