Rikuyo
She honestly didn't give much damn about local animals and spirits dying. If they died off because of a one snapped tree, their weakness was to blame. But spirits becoming scarce left her little option but to feast on humans. Rikuyo didn't see anything amoral in it, just she hanged around in human form most of time and scavenging your own species for food was kinda lazy, but this was an exception as animals weren't as nourishing as humans. And humans to be honest didn't taste too bad, they were kinda like a pork or a boar meat. And so she set off in search for clothes and supplies.
Fortunately for her a traveller strayed off the path, some foolish woman dressed in khaki coloured pants, a shirt and a jacket. First, Rikuyo ordered her to strip, after intimidating her with a display of strength. She couldn't afford her new clothes soiled when she hunted down the woman for food. Then, as soon as all woman's clothes piled on the ground, she rushed towards her without warning, grabbed her face with her remaining arm, lifted her slightly into air and squeezed her head hard enough to crush her skull. The girl tried to put up some resistance, but it was in vain. The redhead feasted on her still warm corpse, voraciously filling her stomach by consuming as much flesh as her stomach could hold. Wiping out blood from her mouth, she dumped the half eaten body into bushes and dressed up. With some difficulty, her arm regenerated, but just one human wasn't enough to restore her to a top shape.
"Ah well, there are more in that giant town. Or maybe there will be some spirit to eat there too." She nonchalantly remarked, without any care that she just ended a life. Hunting and being hunted was something natural after all.
