Shendai obtained a system called the God-Level Comic Shop. As long as customers read comics, they can receive rewards-and Shendai can freely decide what those rewards are. Pain: "Boss, when will Hunter x Hunter be updated? Can that author be more consistent?" Kakuzu: "I want to read rich-man comics. Boss, are they available?" Tsunade: "After seeing Observation Haki, I've been winning nonstop. I've already made a fortune." Madara: "I've read One Punch Man three times. When will I get a Saitama-level body as a reward?"
