Ms. Yuri

Ms. Yuri, known as Ozono Yuriko (大園ゆり子) in Japan, is a character from the MegaMan Battle Network series. In the first game she teaches summer school, and was an ex-member of WWW. In the anime she is the operator of NeedleMan.EXE. She is the twin sister of Ms. Mari.

MegaMan NT Warrior Axess
She is a member of Nebula in Axess and partners with Dr. Regal. She uses NeedleMan.EXE to cause trouble and can disguise herself as Ms. Mari easily, the only difference being the lipstick and hair bun (Ms. Mari shapes her hair like a cinnamon bun; Ms. Yuri's hair is more croissant shaped). She is portrayed as a mysterious character, whose past is unknown and appears in the sidelines, rarely getting directly involved, but often the secondary mastermind to everything, directly below Regal. She is revealed to be Ms. Mari's sister, but is supposedly dead. Her past is explored in an episode involving Misaki, a Net Agent that she tricked. She was on a plane when a meteor sent by Duo crashed into her plane. She survived though (at Duo's request) and gained new powers, such as quick recovery and high Synchro Ratings. Ms. Yuri also became a probe for Duo to observe humanity with Dr. Regal. He orders Ms. Yuri to kill Ms. Mari and gives her a Dark Synchro Chip. But she refuses and in the ensuing battle she is thrown into the sea with Misaki, courtesy of ProtoMan, who was still under Dark Chip influence.
