Possessed Into a Game Where Failing the Tower Means Death

“Hey, everyone… can we please just focus on clearing the tower?”
A dark fantasy game notorious for its brutal difficulty.
I was possessed into ‘The Darkness Tower.’
Six years of my life. Thirty thousand hours of playtime.
The world’s first 100% achievement completion.
Painstakingly created by an ultimate veteran who has played every single character imaginable —
“How the hell am I supposed to reach the ending with a tr*sh build whose only skill is seducing NPCs?!”
— into a joke character made purely for fun.
All I have is MAX Charm and a brainwashing(?) skill.
All I lack is… literally everything else.
To prevent the destruction of the world.
And simply to survive.
The Tower-clearing game begins now!
