Summer Time Rendering

📖 SYNOPSIS

After years away from his small home island, Shinpei Ajiro returns for a funeral he never expected — his childhood friend and adoptive sister, Ushio, drowned saving a little girl. Tragic, but straightforward. Except there are bruises around her neck that nobody can explain, and locals keep whispering about "Shadows" — doppelgängers from island folklore that supposedly appear right before someone dies. Within the first couple episodes, things go sideways in ways I genuinely can't tell you about without ruining it, but let's just say Shinpei ends up trapped in a situation where the island's mysteries become very personal and very deadly.

This is a 25-episode TV series that knows exactly how to use its runtime. The time travel mechanics are tight and well-constructed — if you liked the cause-and-effect logic of Steins;Gate or the brutal loop stakes of Re:Zero, this hits a similar nerve but wrapped in a small-town murder mystery. There's also a Higurashi: When They Cry quality to it — that creeping paranoia where you can't trust anyone in a close-knit community, and the folklore feels less like superstition and more like a warning.

OLM did strong work with the animation, especially the supernatural sequences, and the island setting gives everything this humid, isolated tension. The soundtrack leans into that eerie atmosphere without overdoing it. It's the kind of show where every episode ends and you immediately need the next one, not because of cheap cliffhangers, but because the puzzle keeps getting more intricate.
