Summer Time Rendering

When a seaside town’s legends become lethal, a grieving teen must break a time‑loop to save his friends.

After years away at university, Shinpei Ajiro is summoned back to his tranquil hometown of Hitogashima for the funeral of his childhood friend Ushio, who drowned while trying to rescue a lost girl. The ceremony takes a dark turn when Shinpei’s best friend points out fresh bruises around Ushio’s neck, suggesting foul play rather than an accident. Determined to uncover the truth, Shinpei starts piecing together the last days of Ushio’s life, only to find the island slipping into a bizarre nightmare. Residents begin vanishing without a trace, and strange phenomena—echoes of a long‑forgotten legend—start surfacing. Mio, Ushio’s sister, recalls an old myth about “Shadows,” spectral doppelgängers that appear before a person’s death. As the line between folklore and reality blurs, Shinpei discovers a hidden loop of time that traps the island’s inhabitants in a deadly cycle. With each reset, the shadows grow more aggressive, and the stakes rise for everyone he cares about. Armed with a fierce resolve and the promise he made to Ushio—to protect Mio—Shinpei fights against the inexorable pull of fate, confronting both supernatural forces and the darkest corners of his own past.

A time-loop mystery thriller where a teen investigates his childhood friend's death on an isolated island, battling doppelganger monsters that kill and replace people. Expect repeated violent deaths, creepy body-horror imagery, and tense psychological stakes, balanced by a strong investigative plot and emotional character arcs.
