Wow, I totally agree with you! 🙌 I just finished those same episodes, and honestly, Sentenced to Be a Hero is really surprising me. You're absolutely right about the concept. We're so used to being the "Hero" in anime being the ultimate dream, pure glory and beautiful girls, but here they take it to a whole new level. The fact that immortality is a curse and not a superpower changes everything; seeing them revived only to continue suffering in the war adds a very dense touch of psychological horror. It's not just the fighting, it's the trauma of never being able to rest.
