The action happens in the Dimensional Infinity Fortress. Daki was a demon appearing as a beautiful young woman with a slender and tall yet curvaceous build. Her skin is very pale and has cracks in it. She had two pink flower crescents on her face, with her lime green eyes having the kanjis for "upper" and "six" in them, signifying her rank among the Twelve Kizuki.Her personality is very temperamental and childish. She will frequently let her emotions control her, which leads to bratty outbursts.
