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.

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.
