Characters

Fuyumi Tomoe is a Commander-ranked fighter in the organization Olympia, and the commanding officer of Jack Smith. She is extremely powerful, even by meta-human standards, and is feared throughout the world as the "Demoness of Ice". Among all humans in the world, her strength is believed to be ranked within the top twenty.

Fuyumi usually seems like a cold and unapproachable individual, but she reveals her softer side whenever she is around her younger sister, Koyuki. She has a complex relationship with her father, who views her as a "failure" despite her great talents due to the comparatively far greater potential of her younger sister.

She always seeks out the most powerful opponents, with the intention of defeating them and proving to herself (and to her father) that she is somebody whose strength deserves acknowledgement.
