Headscratchers / Redo of Healer

• So Keyaru, should he use his Recovery (Heal), is forced to experience all the pain that they ever have. Is there ever an explanation as to why this isn't the case for any of the other myriad of uses of his (Heal) he cooks up?
  • It's handwaved by him getting a Pain Resistance skill after getting abused and using Heal many times.
• There are times Keyaru uses Recovery on himself. Why wouldn't he be overcome with the full weight of the 2 lifetimes of his suffering he had to endure, all in an instant, as well as all the accumulated pain he's gathered from others when using it at all?
  • Probably because of the Pain Resistance skill mentioned above.
• Are there more heroes with the same classes as Blade, Bullet, Flare, and Keyaru?
  • The later chapters show that there are similar classes in other countries. Keyaru, Kureha, Setsuna, and Freiya encounter the zombified Rifle Hero, Dagger Hero, and others when going after King Proum.
• If Keyaru had all the power to defeat the demon lord and had just obtained the Philosopher's Stone, what was the point of having a do-over and not just exacting his revenge in the first timeline? Especially since the redo involves him experiencing more suffering to get back to a point where he could exact revenge. And with the stone, he could have the entire kingdom at his beck and call. It's not like anyone is powerful enough to stop him.
  • So he can undo everything they did.
  • He doesn't actually stop many things that he could even after the redo. He could have stopped Norn's massacre of the demon village and only went after her when the merchant was killed, declaring that it was grounds for revenge, even though he could have stopped the circumstances that led to his friend getting killed in the first place.
  • Revenge Before Reason—He doesn't just want them dead. He wants to make them suffer like he did, then give them karmic deaths.
