Detective Conan - Episode 1154: "The Yamahime of Yakushima (part 2)"

The investigation into the murder of Hidaka Yoshimi, a representative of forest conservation on Yakushima, takes a dramatic turn. The suspects—her ex-fiancé Tsukada Taro, her friend Kokusho Kasumi, the mountain guide Kitabeppu Ryoya, and supermarket employee Yamamoto Yuji—are under surveillance. While Conan and the team expose the legend of "Yamahime," a blood-drinking forest monster, as a diversion, Kokusho Kasumi is seemingly attacked by the creature as well but mysteriously survives a fall from a cliff.

Conan discovers a secret passage in Tsukada's sawmill, pointing to illegal trade in protected Yakushima cedars. Despite suspicion falling on Tsukada, the true culprit is revealed: Kokusho Kasumi, Yoshimi's former friend and stuntwoman. Driven by jealousy, she killed Yoshimi, staged her own attack as a Yamahime victim, and attempted to murder Tsukada after he rejected her love.

In the final confrontation in the forest, Kokusho, disguised as Yamahime, faces off against Conan and Ran but is stopped by Kogoro and Yoshimi's father. The resolution reveals how Kokusho exploited the legend to cover her crimes. The episode ends with the culprit's arrest and Tsukada's rescue, while the sad realization remains that envy and vengeance were the true monsters.
