Azaka's classmate and friend, both students at Reien Girls Academy. She has been secretly murdering people since childhood, but she numbed her ability to feel pain in order to seal off her powers. Despite being terrified of being seen as an abnormality, Fujino continues to hide her condition from others. Her murders seem to give her inner peace.
Fujino possesses the unique ability to bend space and objects with her mind, which she uses as a murder weapon by twisting the bodies of her victims into grotesque shapes. She also gains clairvoyance in conjunction with this power, allowing her to manipulate objects without needing to see them.
In the sixth movie, Fujino briefly appears during the opening narrative, using a cane to walk down a flight of stairs with Azaka by her side.
