Benisu

Venis, or Beniko, is the Kuonji head maid and Shinra's personal attendant. She is known to be violent and have a short temper. Her name has a similar phonetic sound to "penis" when said in Japanese. This is shown to greatly aggravate her when the Uesugi siblings make fun of it. Venis grew up in a poor section of an unnamed European city, working at a relative's restaurant while learning to cook, learning to fight while protecting herself from those who would try to grab her, and teaching herself math in the streets. After the restaurant closed, she was picked up off the streets by the Colonel, who was impressed by her skill in cooking and brought her to work at the Kuonji house. She values Shinra's praise and attention above all else because she feels that Shinra gives her a reason to live. She initially clashes with Ren, who refers to her as Beni in order to prevent himself from laughing at her name. However after the two are kidnapped and Ren allows himself to be beaten in order to protect her, she begins to see him in a new light, although he does inadvertently come into the room in which she is still changing.
