Something is making people fall unconscious in an area around an expensive hotel owned by Chrome's former colleague. Chrome sends Lloyd to fill in for lost manpower as a part-time job, but the rest of the usual gang end up there by coincidence.

Selen successfully argues that taking Lloyd out on a lovey-dovey date is somehow beneficial for everyone. As they proceed with their "investigation", Kikyou the spy, believing Lloyd is the unwitting culprit, approaches from the shadows.

Witnesses report a huge snake monster in a dungeon near the city. The king sends the cadets to investigate. However, Alka, Micona, and the mysterious man Sou all get involved for their own reasons.
