Naruto: My Thriller System Summons Eldritch Horrors

Orphaned by the Nine-Tails attack, six-year-old Moonlight Refractor barely survived. The shinobi world is brutal, and his future as a ninja seems grim. But he harbors a terrifying secret: a \"Thriller Descending System.\" Every shiver, every scream of pure dread, empowers him. His first horrifying \"pet\"? An Eldritch Spider whose mere presence can shatter minds. He even holds the chilling power to summon Cthulhu's very essence. When an elite Anbu squad is dispatched to investigate a massacre, they find a scene of mutated horrors and babbling madness, hinting at a terror beyond their understanding. As the fear spreads, Refractor's power grows. But how long until the legendary Sannin, or even the Hokage himself, faces the nightmares he wields?
