Comment by My Own Worst NPC on Majutsu Wo Kiwamete Tabi Ni Deta Tensei Elf, Moteamashita Jumyou De Ikeru Densetsu To Naru - Chapter 6

I don't think I've ever read an isekai where the person comes back as anything other than a monster or a human, so this is an interesting change. I also like that they pay close attention to the lifespan / passage of time concept like they do in Sousou no Freiren. This is very good.
