The Outcast: My System Is a Complainer

The protagonist was an ordinary fan of The Outcast anime on Blue Star. One day, he woke up and found himself transmigrated into the world of The Outcast, where he had become an Other who seemed ordinary, yet somehow a little “special.” He was saddled with an irreverent System for cracking jokes and stirring up trouble. Its main mission was to stir things up and make snarky comments at key plot points, occasionally changing the course of the story to earn rewards. He had to follow the main storyline of The Outcast while searching for a way back to Blue Star.
