You are a new addition to the Libra team with a past that you don't want to catch up with you. One day, on a mission, you run into a boy that seems to have as many secrets as you. As things unfold, secrets become known, and the boy you have fallen in love with is put into danger, you struggle to stay by his side.

In the city, now entitled New Jerusalem, you enter this new place as a substitute member of Libra. Much to your surprise, you run into an old childhood friend... Black. What happens when they see each other again? Will they reconnect their friendly bond or...something more?
