is a member of the Fuma clan at the rank of Jonin. She was among the Fuma clan members who were betrayed by Orochimaru. She was one of a three-member group who guarded Orochimaru's base in the Land of Rice Fields.

Though she was actually a young girl, she constantly disguised herself as a member of the opposite gender (mostly a grotesque man). While disguised, she would use the Antlion Technique (Arijigoku no Jutsu) to cause everything in a certain area to be drawn into a large pit. After removing this form, she is able to use Ephemeral Vengeance (Utakata), creating four wings out of chakra on her back. She can then fire a gigantic blast of chakra at her opponent: the amount is said to be so great that this jutsu can only be used once in a lifetime. She can also fly and teleport while in this form.

She shows extensive loyalty and dedication to her fellow clan members, using her Ephemeral Vengeance even though it would endanger her life. This same respect is also shown towards Orochimaru, who Kagero views as the person who will bring the Fuma clan back into its glory. Kagero died during a fight with Naruto while disguised as Kabuto Yakushi. She constantly made references to the life of a mayfly while in her first male disguise, which makes sense, as "Kagero" can mean Mayfly. While disguised as Kabuto, Kagero uses an unnamed kamikaze technique that uses chakra strings to connect the heart of the user and the foe. When one heart stops, so does the other. This was thwarted however, by Sasame, who gave Sakura Haruno a special seal to sever the string.
