Kodoku (蠱毒, "curse poison") is a recurring venom-based drug introduced in Fushigi Yuugi: The Mysterious Play. It is a uniquely sinister poison that alters one's state of mind. Targets typically experience amnesia while under its effects.

Background

Kodoku is an element of Japanese folklore, however, its origins can be found in Chinese folklore under the names "gu" (蛊) or "jincan" (金蠶). To produce the poison, a sorcerer must seal an array of venomous insects, snakes, and other pests inside a vessel to devour one another. The sole survivor will possess a collective combination of their toxins. The process is then repeated with the survivor and a group of larvae. The final creature will possess a highly concentrated poison, which the sorcerer will extract to use on their intended target. It is typically made into small tablets and packaged in a paper envelope.

Yui using Kodoku

Combined with black magic, the poison can possess varying characteristics based on the intent of its user. Qi suppression and psychological disintegration are its base properties. Kodoku can be used to confuse, seduce, or harm their target by manipulating their memories and prompting hallucinations. Controlled doses are enough to completely change a target's character.

Little is known about the remedies for such a poison. Even the power of a Celestial Warrior cannot heal a Kodoku victim. If it is not administered in large amounts, it may work its way out of a target's system. However, as the poison influences perception, to defeat it requires a sort of mental triumph.

Story

Fushigi Yuugi: The Mysterious Play

Tamahome under the influence of Kodoku.

Kodoku Arc

Kodoku first appears in the hands of Nakago when he gifts it to Yui after she is rejected by Tamahome, their captive in Kutou. Nakago instructs her to lace his food with the drug, however, after multiple attempts, Yui cannot bring herself to poison the Suzaku warrior. Her stance soon changes after catching Tamahome devising an escape plan with Miaka via Chichiri's communication spell. Later, while Yui is taking a bath, Tamahome offers to take her with him back to Konan, despite now knowing she willing chose to be the Priestess of Seiryuu. When she gives him no answer, he turns toward the door. Panicked at the sight of him leaving, Yui decides to use Kodoku. Her handmaidens set out qi suppressing incense, which immobilizes Tamahome. Yui emerges from the bath and places the poison tablet on her lips before slipping the warrior the drug with a kiss. He collapses in her arms and is taken to Nakago.

Hours later, Yui prepares for Miaka's rescue and Tamahome emerges in new clothing and new memories. He now seemingly only has eyes for Yui, and despises Miaka and the Suzaku Seven. Yui is shocked at his transformation and wearily accepts a kiss from him. Nakago is pleased with the results of the poisoning and tasks Tamahome with protecting Yui.

Miaka, Chichiri, and Tasuki arrive at the Kutou Imperial Palace, expecting to meet Tamahome. However, they are greeted by a magical barrier that restricts all magic and a handful of Kutou guards. After allowing Chichiri and Tasuki to hide within the palace grounds, Miaka is thrown in the dungeon. She escapes only to find Yui and a delicious feast for two. The girls discuss their relationship before Tamahome interrupts. Miaka exciedly goes to greet him, but the Kodoku had poisoned his mind against her. He mercilessly breaks her arm. Heartbroken, Miaka tries to leave with Chichiri and Tasuki. But Tamahome attacks and nearly kills Tasuki. Miaka and the two warriors barely escape with their lives as they are forced to leave Yui and Tamahome behind.

Ultimately, Tamahome is able to overcome the Kodoku's effects with the power of Miaka's love for him.

OVA 1

The poison re-appears in the first OVA when Kaen slips it to an unsuspecting Tamahome, poisoning him for the second time. However, he much more easily breaks free of the poison's influence.

Trivia

• The effects of the Kodoku are irreversible by medicinal means or celestial healing, such as Mitsukake's powers.
