“Welcome to the [Dramatic Life] System. Your mission is to enter one anime world after another, repair key plot points, and... become the perfect ‘supporting character.’”
Comic artist Lin Xiao dies suddenly and transmigrates into the “System-task cannon fodder” character from his own story. As the original author, he knows every plot point and every character's weakness inside out. So...
In Jujutsu Kaisen, he is a kind and reliable assistant supervisor at the technical college, smiling as he records everyone's cursed techniques. In Demon Slayer, he is an obscure clerk for the Ubuyashiki Family, reviewing every demon's movements by candlelight late at night. In Bungo Stray Dogs, he is the Port Mafia's most harmless informant, committing every ability and weakness to memory.
The System thinks he's honest and dependable. The protagonist team sees him as a reliable partner. The villains consider him an insignificant passerby.
Until the greatest crisis in the original story arrives, and the protagonist team is on the verge of despair. Then this “supporting character,” who always wears a smile and barely registers, finally sets down his pen.
“I've had enough of this script.” He pushes up his glasses. Beneath his gentle mask lies the calm indifference of someone who sees everything clearly.
“Now, we do it my way.”
The one-line pitch: He transmigrates into a cannon-fodder character in a System mission, then turns the tables by using his author privileges to make the worlds of various anime his own backstage stage.
