SPEAKING OF ANIME

Is there an isekai anime with this kind of concept: Man dies, gets resurrected or teleported to another world. Man dies in the other world, returns back to Earth. And then man dies again so he can go back to the other world because he has unfinished business or something that forces or convinces him to return? Anime or manga, whichever is fine.

Yes, there's Vision of Escaflowne. Hitomi didn't die, but she returned to Earth after getting fed up with the war, strife and suffering, and returned because she wants to make a difference. But I'm specifically looking for the MC dying.
