The Infinite World Where Only I Know the Plot

"What Kakashi? He's nothing but a ridiculous, shoddy imitation of the great Gojo Satoru!" "Forget Kakashi. I heard that the masked Madara in Ninja Village War was actually a fake! His true identity was the Fourth Hokage, Minato Namikaze, who faked his death! Back then, he was really just putting on an act with his shadow clone!" "I've figured out the protagonist of Kamen Rider! It's definitely Keiwa Sakurai! Both his parents are dead, he's kindhearted, and he always gets powerful items. Even his wish is for world peace! He obviously has protagonist written all over him!" "I heard the mages at the Clock Tower are all good people. I once met a mage who said he loved humanity deeply." "..." Hey, what on earth are you people talking about? In this world, anyone who becomes a Planetary Agent can transmigrate to different anime worlds to carry out missions. After just transmigrating here, Ishimori realizes that he might be the only one who knows the plot.
