Ben Tennyson, sophmore at Rysen Academy, the number 1 school in the multiverse for heroes, has become a student advisor. While doing a mission for the school in a dimension that resembles a combination of ancient and future Japan, he comes across an unusual girl who claims to be a sorceress. Feeling that she has potential, Ben decides to test her and accept her into the Academy. Soon, through an unusual spell placed by the young girl, Ben discovers the Shogun Aliens, new enhanced versions of both his normal and Ultimate forms that contain power exceeding even that of the Regal Seven. But the problem is...... Kurayami and Zs'Skayr also desire this power.

The final battle for love, life and liberty has begun! Ayla has had to defend her people in the past, but this time, it is no mercenary rabble outside the gates of her castle: it is the army of the Margrave von Falkenstein himself. Her people are outnumbered and have nowhere to run. But they do have one last, desperate hope: A knight in blood-red armor with the face of a god and the heart of a devil. Will the enemy succumb to him? And more importantly... will Ayla? The third and final volume of Robert Thier's "Robber Knight"-Trilogy.
