Tokyo: Gain Fans to Grow Stronger, My Stepsister Is My Top Supporter

The moment the System arrived, Kashiwagi Tsuki knew one thing: being liked would make him stronger. The more fans he had, the healthier his body would become and the more outrageous his skills would be. But he started out with a frail body that might not last until he turned twenty. All he could do was grit his teeth, make videos, and pay for promotion, hoping strangers would give them a glance.

Just as he had finally scraped together a few points, his stepsister moved into his home. Worse still, the top donor, "Demon King," who helped him edit his photos every day, was messaging him in a way that sounded less and less like an ordinary friend. Kashiwagi Tsuki had a vague sense that something was off, but he didn't have time to investigate. A wealthy shrine maiden at his school was being pressured by her family to go on blind dates and had made him her shield, while the top donor seemed ready to take off his mask too.

The trouble kept growing like a snowball. To stay alive, he could only keep attracting fans and getting stronger, turning everyone who came near him into a believer. But if one day his most devoted top donor suddenly stood before him and revealed their identity, should he be grateful or run?
