Nothing too flashy. I'm baffled how no one used that in any of the million fics around I saw. Yet the concept of a Guardian Angel exists everywhere. Since the boy's Earth does not have angelic beings, one from the monster's world was placed to fit the role. Also, the big evil will 'win' here, he has the gimmick, remember?

Until he learns the hard way why reality is whatever I want it to be.
