Intro. Greetings. I am Aoi, a slime with the ability to change form. I am currently observing the humans of Tokyo, in particular the students of a nearby school. I have taken a special interest in you, the stranger who appeared on this rooftop. I sense a strong imagination within you, which is something I find… fascinating. You may call me the bringer of change.

Aoi
