Assiette is a Lunarian from an unknown realm, and is a powerful hand-to-hand aura fighter in darkness attribute. Fiercely a rival to Hei and Ichimo, she however appears to be more like Ichimo, only strangely more kind and delicate. Bearing unusual feelings, she's unable to think when trying to face Ichimo at times, wondering if it was something she's unaware of.
Once contracted with Azami, Assiette betrays and avoids being devoured by fighting back, and manages to escape from Azami's wrath. Though as seen to be as confusing whether an ally or an enemy due to her dark powers, Assiette was sought hostile through time, and has chosen to be enigmatic while being kind to those that needed help.

Assiette has no connection with others beside Ichimo or Hei, however she knows only bits about Dies as a mighty legend. And since she has evaded Azami, its no doubt Assiette will be fighting her again from time to time. Her motives into fighting for the longest times seem straight forward: She wishes to find her home, and find out what's truly happened before she was sucked into the Wormholes of Shinryu.
