The head and highly respected man of the yakuza that is said to fight the strong and help the weak and nicknamed "The Raging Dragon of the East". However he is revealed to be a weak ill man who gets nosebleeds when he gets overexcited, but loves his daughter dearly and only wishes for her to be happy and untainted by this world.

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.

The main protagonist of the series. Despite his looks and easygoing personality, he is a capable and strong worker who works for Benika as a dispute mediator. When he was young, he lost his family in a terrorist attack. As a result, he became withdrawn from the world until he met Benika. He wished to be as strong as her so he could live on. Benika decided to leave him at the H�zuki household. It was there that he trained his body extensively and learned H�zuki-style martial arts. His kind demeanor attracts considerable attention from the opposite gender, though he is completely oblivious. In emergencies, he is able to produce a large 'horn' out of his right elbow which classes him as "Type 1 Class 2 Fighting Demon". This special weapon was designed for the purpose of assassination. This lets him use his full strength in combat, but shortens his lifespan. When he is forced to fight, his personality changes to a more aggressive one. Between the anime and the manga, there are differences in the way Shinkur� is depicted. In the anime, Shinkur� is not as confident and appears to have less control over the Hozuki horn.
