Dungeon Defense

His parents were the worst kind of people imaginable.
Cruel, selfish, and utterly corrupt… their deaths left behind only one thing of value.
An inheritance of 500 million yen.
With no family left and no reason to follow society’s rules, the boy decided to live life exactly the way he wanted.
And his escape from reality became a ruthless online game known as “Dungeon Attack.”
A brutal strategy game where players struggled endlessly to defeat powerful Demon Lords.
But what countless players failed to achieve…
he accomplished alone.
After countless hours of planning, manipulation, and perfect strategy, he became the first player in the world to defeat every single Demon Lord in the game.
The ultimate achievement.
The final victory.
And yet… that was only the beginning.
When the game suddenly presented him with a strange mysterious question, he answered without hesitation.
The next moment, his world shattered.
When he opened his eyes again…
he was inside the game.
Not as a hero.
Not as a conqueror.
But as the weakest and most insignificant Demon Lord of them all—
Dantalian.
Ranked 71st, mocked and underestimated by every other Demon Lord.
He had no army.
No power.
No allies.
Only two things remained:
• His memories of defeating the strongest Demon Lords.
• And his dangerously sharp mind and eloquence.
In a world filled with betrayal, war, and ruthless rulers…
strength alone would not guarantee survival.
But cunning might.
The weakest Demon Lord was about to begin the most dangerous game of all.
A story of strategy, survival, revenge… and an unstoppable rise to power. ⚔️👑
