Does anyone know of any animes that start off with, "Hey wake up!" And then the main character goes off to save the world?
I enjoyed this theme in many TV shows and videogames, and was wondering if there were more instances where it popped-up (since I'm approx. 15 years behind on anime).

Edit: Well! I found Noein and Oh My Goddess while browsing animes! They both fit :)
Just like the Ocarina of Time Opening.
