Tower

Yeon-woo had a twin brother who disappeared five years ago. One day, a pocket watch left by his brother returned to his possession. Inside, he found a hidden diary in which was recorded “By the time you hear this, I guess I will be already dead….”

Jinhyuk, a gaming Nutuber, was the only person who saw the ending of the game [Tower of Trials]. However, when the game’s popularity declined, it became difficult for him to continue making a living as a gaming Nutuber. Since he already saw the ending of the game, he was about to quit playing. But that day, [Tower of Trials] became reality, and Jinhyuk, who knew about every single thing in the game, took over everything faster than anyone possibly could! “I’ll show you what a true pro is like.”

Yeonwoo’s brother disappeared years ago, and he’s devastated to learn of his death. As he copes with his loss, he’s given a pocket watch and learns there’s more to his brother’s death: he was betrayed while competing in the Tower of the Sun God. Now it’s Yeonwoo’s turn to use the knowledge his brother left behind. Can Yeonwoo (call sign: Cain) navigate that world and gain enough power and experience to reach the top of the tower, defeating his brother’s enemies and all those who stand in his way?

[Which guide will you use?] A mysterious message came to me the same day the end of the world befell us and a survival game began. A tower that makes humans distrust one another, instigates fights, and leads humanity to destruction… I will not be shaken. I will see this to the end with the people I trust. …Yes, I will create a happy ending with them all!
