Fuku

Petite and short for her age, Fuku ties her long dark-brown hair into a single braid that hangs behind her. Her violet eyes lighten toward the lower edge of the iris, and the irises themselves are pale and shaped as tall, narrow rectangles. For work she puts on a peaked tan beret along with oversized round spectacles. Her clothing appears to be the shop's standard outfit: a simple red-and-brown haori layered above a shirt with a white collar, and over that a white cooking smock.

Generally courteous, Fuku nonetheless carries a heavy load of worry about money and the family trade. She is certain the burden of keeping the business afloat falls on her, since her father's shop is doing poorly and her expecting mother can no longer help out, though Tomi insists that such cares ought to rest with grown-ups rather than a child. Stubbornly, she dismisses any talk of demons as superstition and will not stop selling after dark merely because her grandmother fears the creatures prowl at night. That conviction crumbles the moment Kyojuro Rengoku cuts down the Slasher right in front of her, after which she admits she was wrong and offers an apology to Tomi for doubting her.

Fuku is an everyday civilian with no combat training, no Breathing technique, and no supernatural gifts of any kind. During the Mugen Train storyline her survival depends entirely on Kyojuro, who first slices through the marked demon's heel and then beheads it before it can finish strangling her. She, her grandmother, and the Slasher were all created specifically for the anime and have no counterpart in the original manga; her debut comes in episode 27.
