From Kodansha:
A young woman, net nickname "Mushi-nee," finds herself sucked into a world not unlike the online real-time strategy game that was her only escape. She had captained the "Arachnea" faction but it's one thing to do on a computer, and another to find herself face-to-face with giant arachnids who hail her as queen! But rather than shrink from her fate, she steps up to become the conquering queen she knows she can be.
