Fumie Hashimoto (橋本 文恵: Hashimoto Fumie) is the seventh member of the Coil Dennō Investigation Agency. She is an elementary school student who has brown eyes and brown shoulder length hair. She befriends Yasako almost immediately, and has a quick-witted, playful nature. She is an experienced hacker and an adept user of metatags, and makes use of her digital pet, Oyaji, in her investigations. She is reported to be 120 cm tall, weighing 27 kg only. Her younger brother by two years is Akira, who has a mutually acrimonious relationship with Fumie. Akira perceives her as too much of a bully (to him) and tries to document these moments behind her back to use against her in the future.

Her seiyu in the Japanese dub is Sachiko Kojima.

She is Daichi's rival and their loud personalities cause them to often clash and fight—despite this he has feelings for her that she hasn't noticed.
