The Black Cat Air Squadron at the End of Its Rope

【Aerial Combat + Another World + Plot】Long, long ago, several enormous holes suddenly appeared in the skies above the Desolate Lands. All kinds of objects fell through them, along with people from other worlds who called themselves the Youhan, Aimerike, Deisi, and Luxiya, among others. Towns sprang up in places that had once been utterly barren, and oil wells and factories rose from the wilderness. Most of all, the objects known as “airplanes” were quietly changing people’s lives. Though the portals eventually closed, the technology and knowledge left behind took root and flourished here. Airplanes let people soar through the skies, and the seemingly endless supply of oil laid the foundation for aviation to thrive. The great age of aviation has arrived in the Desolate Lands.
