Bando Mitsugoro VIII's Hachimaki

Origin
Bandō Mitsugorō VIII was one of Japan’s most revered Kabuki actors until his untimely and unusual death. In 1975, he ordered several servings of fugu kimo, the liver of a pufferfish that proves extremely lethal if prepared incorrectly. Although banned by restaurants at the time, he claimed to be able to survive the poison. He died in his hotel room seven hours later from convulsions and paralysis.

Effects
Gives the wearer an intense desire to eat fugu. The hachimaki stores the poison inside of it until another person wears it. That person gets poison injected in the bloodstream and dies over a period of several hours.
