Starshine Academy: Calamity Impact 3rd (Haitus)

One airship. Four exorcists. After the First Eruption of Nether Demons had caused the death 300,0000 people and the Second Eruption wiped entire cities off the map, Celest Vagabond had done his best to evolve humanity. Improving technology and magic to the point that it was possible to fly airships to take down as many disastrous demons at once. Even giving them to students so they could hunt Demons independently. On board the Arkra Cruiser was Captain Ryan of a mysterious origin, and three of his subordinates. They got a mission to check out some abnormalities that were happening near the city they came from. This would lead them to the first clue to their pasts.
