Maybe We Are Bankrupt

Each horde of demons consisted of 500 soldiers, some of whom could fly, others could only walk.

They arrived by ship, some were shot down by cannon fire, but many survived and some ships escaped being hit by the attacks.

Solsticea had a large coastal region, so invasion by ship is relatively easy, the rulers never thought that one day they would be attacked in this way. This was a very stupid thought, since the Northern Continent had always been known as the Demon Continent, yet it had been a few centuries since any Demon Lord had appeared.

The demons began to attack every form of living being they came across, they made no distinction between monster and human. Or belonging to humanity.
