The room was filled with an insanely bright light, as if hundreds of sparks were falling directly on the main character. And then, out of nowhere, a cute blonde appeared in front of him, seeming completely exhausted. Here the guy learned that his brother’s wife actually possessed powerful magic, just like her new acquaintance.
