About the book: year / And how did this happen?! Having strongly believed in ourselves, we made a mistake - we allowed the Voskhod organization to get too close. People eager to study the higher spirits deprived me of what was most precious to me. I don't know what to do. I don't know where to look for Aika and the others. How much time do I have? No, how much time do they have... In addition to this, they also need to find a place where all the inhabitants of the underground city can move. So much at once...Calm down, Rin, calm down. Inhale and exhale. We will definitely figure everything out. We will look for girls and, at the same time, a place that matches the description, which once served as the home of the strongest higher spirit. I swear to God, when I pull out Aika, Kuro and Aurora, I will not leave a stone unturned from this damn organization!
