Juri (樹里 Juri?) is the referee of the Dark Tournament after Koto was forced to switch to commentary.

Juri is an unknown type of sea creature demon, given the webbed tail and ears as well as the fin-tipped tail. Juri has mint-green hair, like Yukina. Her skin is tan and she wears blue lipstick and eyeshadow. She wears a tight black bodysuit with a hole in the front and back which exposes her belly, navel and back. She also wears a small pink top, a matching pink skirt, red arm and leg warmers, a small purple bow tie, and a pink bandana. Juri is apparently something of an idol of the Human and Demon Worlds.

Juri doesn't seem to be as sadistic as Koto (though only in the English dub version was she a sadist), but she seems much more cowardly as she is seen constantly fleeing away from the fight when she gets scared, claiming she is not paid well enough or curled in a fetal position wondering where her mamma is. She is also a good deal more squeamish than her friend, often expressing disgust at the remains of dead contestants. Despite this, she is still somewhat professional, as she noticed that during the fight between Kurama and Karasu, Kurama had fallen and she began to count. Due to this, even though Kurama had killed Karasu, he lost the match as he had been down for just over ten seconds. Like Koto, she doesn't seem to hold any prejudice against Team Urameshi.

In the manga epilogue and in the All or Nothing special, it is shown that she had changed her line of work (in the anime, she's seen working as a waitress during the Demon World Tournament). Now, she has become a famous character in Demon World, enough to win a cult of supporters, along with Ruka and Koto where she develops a crush on Suzuki, which is also shown in an ad during the events of Eizou Hakusho.
