Crossing hundreds of years, Hero Lux once again arrived at Demon King City.
Last time he came, Hero Lux was prepared to sever the cycle forever.
He believed that as long as he completely destroyed Demon King City, the Demon King would have no way to come to this world again, and the world could remain peaceful forever.

Once the enemy, the Demon King, was gone, it wouldn't take long for humanity to fall apart, engaging in fierce battles for their own interests.
At that time, Lux still held on to a sliver of fantasy, believing this world wasn't beyond hope. Even if wars occurred, people who recognized the preciousness of peace would immediately stop the wars and find other ways to solve the problems.
