Three worlds in one

It was a regular old high school, it was the only thing that could be said about the place. Kids were running through the school halls in their uniforms. Some were playing in the playground while the teachers continued to tell off some of them for being too energetic.

On top of the school roof, a single student was seen looking out behind a fence. He had red spiked hair and looked at all the students and the city out in the distance. 

"You always did like high places with nice views. You're quite easy to track down. You know if someone was looking for you it would be easy to find you." A female student said walking towards the red haired one.

"Well, it's a good thing that no one is looking for me anymore. I guess it just means I'm no longer needed." The boy said with a smile. "The days of the great dragon Sen protecting the human race seem to be over."
