Truth is something you can only understand by seeing it with your own eyes.
The history of the war between humans and demons is long, spanning nearly five hundred years.
We have an arch-enemy, the Demon Lord Lei Fostaria. We must slay the Demon Lord and bring peace to the world.
The only existence capable of opposing the Demon Lord. The one who will exterminate the demons and slay their lord. In the past, there was a hero named Serena Azfall, hailed as the strongest in history, but she was brainwashed.
We, the Kingdom, must win this war. The people massacred by demons will not return. We must reclaim the stolen territories. Demons are evil, and the Demon Lord is a cruel and cold existence.
