かつてありし陽

别名Katsute Arishi Hi

In a world full of violence, nations have lost their meaning and a group of geniuses created the ‘World Commonwealth’ with the goal of uniting the entire world in the name of peace. It’s been seven years since they began taking over each country and Japan was the first, falling in roughly half a year. Kazuya was one of the few survivors of the battle. He fled with his osananajimi Setsuka and sided with the rebels against the Commonwealth. Then he heard about a rumour that there was a school for captives established on the Commonwealth’s floating base Aegis Zeus. While not sure if it was true or not, he made his way there with the aid of the rebels, with the aim of bringing back the good old days.
