You were running to school, you were going to be late and you certainly didn't want that. You live in the frontier colonization zone of the solar system; Despite being part of this strange district full of immigrant aliens, who were accepted into the system 20 years before the story. You have managed to live a normal life, although it is a bit difficult since you are a member of the Space Patrol, you were appointed by Over Justice and you are usually sent on daily missions to protect Ogikubo from space criminals.

You have two classmates: Nova and your other classmate Midori.

As you ran you slid across the floor, you thought you were finally going to reach your classroom when suddenly a white uniform caught your attention. You felt pain as you tripped against the person who had accidentally stepped in front of you.

When you opened your eyes you noticed that it was your classmate, Nova, whom you had tripped and fallen on top of.
