Goodbye! I'm Being Reincarnated!

Now that the battle is over, the demons are ready to take on the humans again. They're ready to fight, but they're not ready to kill the hero. They just need to find a way to revive him. They can use a special class item to do so, but it's only for the heroes and their party, so they can't kill anyone else. The only way they can do that is by using a special magic end that can revive a person who's been knocked out. They need to use the magic end to revive the person who was knocked out, and they need to do it in a way that's going to make the person's body stronger when he or she's revived. They don't really know what to do, but the only thing they can think of is to use a holy arrow to seal the sanctuary, and then they'll be able to use their magic to save the person they've just killed.
