An odd guy who is always dressed in a Nyanmaru costume, claiming he is Nyanmaru even though they pointed out to him there is a zipper on his back. He is the only other confirmed "Rare Kind" and has the ability to nullify other powers. He's rather crafty, and takes advantage of the Code:Breakers (namely, Ogami and Toki) quite often when they move into his Shibuya mansion. Although Shibuya's not in possession of any special powers, he's still an extremely able fighter. He trains Ogami Rei and Toki in preparations for the battle against "The Seeking One," and forces them to call him "master." Shibuya's later revealed to be "The Seeking One"'s sword teacher and Sakura's biological father. He wears his costume to prevent Sakura's memory from awakening, and wishes for her live a normal life, a fate usually denied to a Rare Kind. Only Rui knows his secret, and often uses this to threaten him. Like Sakura, when he temporarily loses his Rare Kind's power, he takes a miniature form of himself. In the battle between the Re:Codes and the Code:Breakers, Shibuya remained on a neutral stance, and didn't participate in the fight until "The Seeking One" had retrieved the Pandora box. In the next arc, he temporarily removed his costume and rescued Sakura, Ogami and Haruto from the Code:Breakers.
A brash, bespectacled girl with braided hair who has rather vivid bish�nen sexual fantasies. Her apparent role in the anime is to provide comic relief from the side of the girls. Although her physical attributes manage to attract the attentions of the Baka Trio every now and then, the sight of her face is enough to put an end to any perverted thoughts they may have.
Tubalcain Alhambra is one of Millennium's artificial vampires, but much more powerful than Luke, Jan and the basic Millennium troops.

Taichi Hiraga-Keaton's friend and business partner. Together they run a insurance investigation agency located in London.
Sakura's mother has the appearance of a grade schooler, which is why she was mistook as Sakura's younger sister. She likes to cosplay, always dressing up in different attires and having a closet full of different outfits. Despite her appearance, she is shown to have a violent side after consuming alcohol. Rei describes her as "being blind in love for her children" because she has taken pictures of every memorial moment of her daughter (from her first day of school to the first time she ate wasabi). Ironically, she whines that she should have taken more.
A girl who Shinkur� lived with when he was young and also his sparring partner. Her soft demeanor (albeit with yandere tendencies, triggered by other girls approaching Shinkur�) hides the fact that she is a strong fighter, whom Shinkur� acknowledges to be much stronger than himself, despite her being older by just one year. Yūno is upset that Shinkur� has not realized he was her first love. Even now, she still has feelings for Shinkur�, always finding excuses to spend time with him, such as cooking meals for him. However, her advances tend to be very threatening (most likely because Shinkur� always has another girl with him) and scare him into just letting her hear what she wants. Yūno resents the decision Shinkur� made in deciding to move out her household to live on his own and fears he will change into a hooligan. She has made it very clear that she wants him back in the H�zuki household. Yūno has a younger sister named Chizuru, who is five, who also has a crush on Shinkur�. Even though the H�zuki family are no longer assassins, their grandfather expects Yūno and Chizuru to carry on the H�zuki family martial arts. In the anime, Yūno is much more assertive in her advances towards Shinkur� and does not appear to have the yandere tendencies.
