Suppose a Kid from the Last Dungeon Boonies Moved to a Starter Town, Vol. 6 (light novel) by Toshio Satou

Lights, Camera, Action!​ There’s a casting call for movie extras and stuntmen, and the agents are looking for one of the military cadets! With the help of a little magic, Alka transforms Lloyd into a handsome young man perfect for the role. Meet Roy Akizuki—fresh new face in the action–movie industry! One small change in the script lands him the starring role, and thrown into a cast of chaotic actors, Lloyd improv skills are immediately put to the test. It’s getting harder and harder to tell if the scenes are just on-screen drama or actually happening...Either way, they’re starting to veer off script, and it’s too late to turn back now!
