The Moon that Watches

Ren Ichiro was never special—until the night he died.



Stabbed in an alley by someone he trusted, Ren wakes up ten days in the past, his body intact, his memories unchanged, and a strange new presence following him: a mysterious system called Tsuki. But Tsuki isn’t a guide. It offers no advice, no powers, and no salvation—only a cold countdown to his death and the silent promise: I am watching.



With time slipping away, Ren must navigate a familiar world now shadowed by suspicion. Friends may be enemies. Strangers might know more than they let on. And at the center of it all is Yuki Arisawa—a quiet classmate whose sudden interest in Ren feels more than coincidental. She’s the only one who might help him unravel the truth behind his murder… if he can trust her.



Caught in a loop with no rules and a system that only observes, Ren has ten days to rewrite fate—without knowing who’s pulling the strings.



The moon sees everything. But it never speaks.
