The current Code: 03. At first glance, he seems pretty calm but goes on a rampage if anyone even brushes him. Oogami described him as the "most barbaric code breaker". He speaks using Kansai-ben. Despite his violent tendencies, he genuinely rewards kindness, and apologizes by giving gifts to people. In chapter 35, he gives Sakura a stuffed animal for her genuine concern for his well-being, and in Chapter 36, he attempts to get a golden toy for Toki as compensation for beating him up, even though he didn't want it. In chapter 36, he admits that he hates Eden, but has joined the organization so that he can take it down. A major love of his is the stuffed animal named Nyanmaru. In recent, he has mistakened Sakura as the true identity of Nyanmaru when her saying reminds him of the animated character. His ability is 'sound' which allows him to listen and identify sounds from distance, travels in the speed of sound and manipulate soundwave to attack. When he temporarily loses his power, he becomes a red-haired cat. Like Heike, he too seems to not prefer the idea of killing, as he went out of his way to save a pregnant woman and a small child from an explosion. His addition to the Code of Hammurabi is "An Eye for an Eye, a Tooth for a Tooth, and the Requiem of Fury for Evil." His Lost Form is a red cat with simple, black eyes, but he keeps his necklace on. It's later revealed that the reason Yuuki works for Eden is for the sake of his childhood friend, Makoto. As a child, Yuuki was ostracized due to his special power, and Makoto and Shigure (another special power user, a future Re:Code) were the only ones to approach him. Once, Yuuki selflessly tried to save others from the rubbles of a collapsed house, and Makoto got severely hurt protecting Yuuki. Since then, he has been in a coma, which caused Shigure to hate Yuuki and vow to kill him to avenge Makoto. In the latest chapters, Makoto is shown to partly regain his consciousness, and is able to send a message in Morse code to Yuuki, telling him to bring his friends the next time he drops by.
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.
Ikuno Komaki is Manaka's little sister who has a chronic illness that keeps her in the hospital. Prior to episode two of the OVA, her health improved and she was released, thus she was invited to the beach along with her sister. Ikuno is very supportive of her sister and she tries her best to support Manaka in her affection towards Takaki.
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.
She is yet another tenant of the building Shinkuro lives in. She always wears black and calls herself a very sinful woman. She likes cats and usually keeps to herself except when it comes to Shinkuro and Tamaki. Her attitude can be considered sarcastic most times.
A woman who works as the middleman for the Akuu Company, a secret mercenary group of assassin and skilled individuals.
