So I've been doing some stuff for Fooker Emblem, and in one of the chapters there is a recruitable NPC unit. In the chapter that he appears, if he dies as an NPC unit, he comes back the next chapter as playable character. This doesn't happen if he dies as a PC in the same chapter he appears. How do I make it so that if he dies as an NPC in the chapter he first appears, he doesn't come back in the next chapter?
