Nenene Fujiwara

Nenene Fujiwara is a former Code:Breaker that gave her life to save her brother Toki. She lost her memory and now does not remember her brother.

Background
She is Toki's older sister (although she seems, looks, and acts younger than him). She doesn't know that she has a brother. She is in second grade and vice-president of the student council. Like her brother she has heterochromia but hides it by wearing glasses. She has a strange habit of grabbing Sakura's breasts out of nowhere (something her brother tries to do to Sakura as well), cuddling herself against them and falling asleep on them; going so far as to name them (Mii-tan for the right and Hii-tan for the left). She also appears to have a possessive attachment to them, where after hearing the rumors that Sakura is going out with Rei she latched to her tightly and states she won't give up Hii-tan and Mii-tan. In Chapter 34, she is hinted at being the last Ex Code:Breaker where in Chapter 45 it was confirmed. Though it has been stated that she was killed by Re-Code:03, which could explain having no memory of her brother. She refers to Toki as Magness, based on his magnetic ability. Her code number, or addition to the Code of Hammurabi has yet been stated.

In chapter 74 it is stated that Nenene's power was magnetism, and was of such a high level (she gave half her power to Toki, but still had enough to carry on being a code breaker, and for him to become a code breaker), she is shown levitating several magnetic weights. In the same chapter she also gave half her power to Toki because he wanted to leave the house because he didn't like being there with people with powers, so Nenene gave him half her power so he would stay because he was her brother. Heike mentions to Toki that by doing so, Nenene gave up half of her life, thereby significantly decreasing future mission success rates. In the most recent chapters, it is highly suggested that her memories have started to return, as in chapter 89 she appears at the mansion, calls Heike by name, and tells him to stop bulleying her "lovely brother" Toki. She also appears older than before, as she looks to be roughly equal to Toki in height, has discarded her glasses, and dresses in a school uniform more suited for older students. Whether this means her half of her and Toki's magnetism powers has also returned remains to be seen. In Chapter 112 it suggested that she is associated with the Code:Names. She was seen at the Heisei Gakuen High the current hideout of the both the Code:Names and the Code:Numbers. (excluding Ogami, Rui and the RE-Codes).

In Chapter 114, Heike told Nenene about the Code:Breakers, and the hunt of Oogami's left arm. Which makes Nenene no longer safe since she has the knowledge, making Toki infuriated at Heike.

In Chapter 115, Saechika mentioned that Nenene is better than amateur, since she is the only Code:Breaker alive from the former group and is the best person to fill in Code 03, 05, 06. In other words, good replacement for Yuuki, Prince or Oogami.

Heike also mentioned if Toki failed to bring back Code:Emperor, he would send out Nenene to go after him, much to Toki's disbelief.

Personality
Throughout her appearances in the manga, she is portrayed as someone who is childish and naive to the point she seems to be like a 10 year old, possibly due to her loss of powers and her memories. But she is very kind and polite to everyone she meets, and those around her, especially Toki, would want her to be happy and safe.

Relationships

Toki is her brother, but she doesn't remember it. However, at Chapter 89, her memories start to return. The reason is that Pandora's Box was opened.

Abilities/Powers
