In the remote Edo-era village of Okitsu, pearl divers are being torn apart by sharks that have been bewitched by the sinister cult leader Koushirou, who seeks to harvest the gems from their mutilated bodies. Desperate, the village hires Kotaro Shiozaki, a temple guard trained in the art of the blade, to eliminate the threat. But as he delves deeper, he encounters Kikuma, a mysterious female ninja whose motives are as murky as the depths the sharks haunt. With the ocean turning red and the cult’s dark magic growing stronger, Kotaro must confront a nightmare where nature itself has been corrupted by human evil.
User Reviews
“I was expecting a silly B-movie, but it surprised me with some genuinely tense underwater scenes. The shark effects are practical and creepy, and the ninja action is well choreographed. It's not perfect, but it's got a fun grindhouse vibe.”
“The premise is ridiculous, and honestly it never quite hits the mark for me. The acting is wooden, and the plot feels rushed. It's cheesy in a bad way, and the scares are more laughable than terrifying. Could have been so much better.”
“I came for the gore and I wasn't disappointed. The shark attacks are nasty and the kills are bloody. It's not high art, but it's a solid time for horror fans who don't mind some ridiculous fun. The ninja lady is cool too.”
“It had its moments, especially the dread of the shark-cult concept. The atmosphere is decent, but the execution is uneven. The climax felt rushed and left me wanting more. It's a middle-of-the-road horror that could have been great with a better script.”
