A classmate of Sakura's, and the Student Council Secretary. For no reason at all he would set up a table in the middle of a hallway and drink some tea. He seems to enjoy bondage, as he constantly carries a book around with the cover having the woman in a kinbaku. He is later to be revealed as a Code: Breaker as well, under the code-name 02 (and with this all the even Code: Breakers have been introduced: 2, 4, and 6). Like Rei he also uses the same Code of Hammurabi, but instead of Evil for Evil he replaces it with "and eternal shackles for the evil." He also doesn't seem to prefer killing his targets, stating that "life is precious." Heike's power is controlling light. His Lost form (the form each Code:Breaker takes when he/she temporarily loses his/her special power due to overuse) has not been revealed, as Heike always wears a full-body metal armor to cover himself when in his Lost form, but others describe it as "something incredible". In chapter 109, it's revealed that Heike is actually over 100 years old. He was born in the Meiji era and enlisted in the Imperial Army, all the while concealing the fact that he had a special power. At that time, the government was secretly carrying out a project to exploit the powers of power users, who were said to be of great aids to Japan in times of crisis. However, as Imperialism took over, the Imperial Army started a relentless purge of harmful and rebellious power users. It was at that time that Heike met the Code:Emperor, who were using his flames to protect fellow power users. Enchanted by the Emperor's strength, Heike joined him, and with 2 others (making them a group of four), founded Eden, an independent organization with focus on the research of special powers. Heike's shown to have a berserk side, which Yukihina describes as being akin to a mad dog, in contrary to his usual composure and just attitude.
A remnant of the strongest power user known to Eden, the "Code:Emperor's" soul which resides in Ogami's left arm (the arm of the Code:Emperor grafted into his body) and is the actual controller of his Azure Flame power. He's conceited and often looks down on the Code:Breakers, but can be easily moved to tears. After he finds out that Rui is his favorite singer "8 tears" he starts to have a crush on her. His power, beside controlling the blue flame, can be used to summon dead people's souls from hell. Later on, he's shown to take the form of a crowned young boy inside Ogami. According to him, this form is merely temporary, due to the lack of his full original strength. In the Meiji era, the Emperor, along with Heike, Sakurakouji Sakurako, and one other person, founded Eden.
The security guard of the basement in Shibuya mansion. She's a mechanical doll created by Shibuya with the power to "drain" power from power users, thus making her a perfect protector of the Pandora's box. She bars anyone from entering the basement, except Ogami, whom she seems to recognize. Inoichi used to be Sakura's caretaker when she was little and raised inside Eden's laboratory. She's programmed to protect Sakura, and tends to follow her everywhere. A mechanical doll that was created in order to protect Sakura. Her purpose of living is to protect Sakura. Sakura had a flashback in chapter 66, which revealed that she knew Inochi and was protected by her before she was adopted by the Sakurakouji family. Sakura also remembers that Inochi always stayed by her side when she slept and Sakura always sat on her lap when she was a young girl.

Minato Namikaze was the Yondaime Hokage of Konohagakure and the man responsible for sealing the nine-tailed demon fox inside Naruto Uzumaki when he was born. Doing so cost him his life, and before dying he asked that the villagers not see Naruto as the monster within him, instead wanting him to be viewed as a hero, a request ignored by the villagers. "Namikaze" translates literally as "Wave wind." "Minato" translates as "Harbor" or "Port." Minato shares a number of traits with Naruto, namely in appearance and attitude. Such comparisons are common throughout the first part of the series, and in the second as well. The second part of the series reveals that Naruto is his son, hence the comparisons, born to Kushina Uzumaki. In his youth Minato, along with two other unknown Genin, was a student of Jiraiya. Prior to becoming Hokage, he was also the sensei of Kakashi Hatake, Obito Uchiha, and Rin Nohara. Minato is said to be one of the greatest ninja Konoha has ever produced, with natural talent that had not been seen in many years. He specializes in using the Hiraishin no Jutsu, a technique the Second Hokage, Tobirama created, which essentially allowed him to teleport to any location with the use of a special seal. By attaching the seal to a kunai or an enemy, Minato could teleport to the location of the seal unnoticed, allowing him to wipe out nearby opponents almost instantly. This ability led to his title as "Konoha's Yellow Flash," and it caused him to be seen as so dangerous that a flee-on-sight order was given in regards to him during the Third Ninja War. He also created the Rasengan, a technique that does not rely on hand seals but instead uses a concentration of spinning chakra in one's palm that causes immense damage to its victim on contact. Later in the series it is revealed that technique is actually incomplete. Minato had planned to add his own nature manipulation training to the Rasengan, making it even more powerful, but could not manage to prior to his death. Later during the war he is resurrected by Orochimaru with Edo Tensei alongside all the deceased Hokage on Sasuke's demand. After Sasuke chooses to protect the village, he goes and joins the battlefield along with his fellow Hokage to help the Allied Shinboi Forces in their fight with the Juubi.
