Japanese Horror: I Adopted Sadako from the Start

Transmigrating into a Japanese horror world. He thought he could enjoy a leisurely life growing corn in Okinawa. But as the number of children he adopted kept growing, Uekawa Yu realized there was something off about his kids. His eldest daughter, Sadako, has black hair and eyes, likes to squat in wells, and occasionally makes the electromagnetic signals flicker. She keeps shouting, "Father belongs to me!" His second daughter, Kayako, likes to cosplay as a spider in the stairwell, and often makes a strange, croaking sound in her throat. Looking at the courtyard full of creepy, filial daughters, bizarre beings, Tomies, and Shiros, Uekawa Yu, worn out to the core, can't help asking himself: "Can I really survive this? Are there even any humans left?!"
