The monster appears as a Kagami mochi. Basically its body consists of two round mochi (rice cakes). The smaller mochi is placed atop the larger, and with an a daidai (a Japanese bitter orange). It sits on a stand called a sanpō over a sheet called a shihōbeni.
It is a summoned monster of Shiramochi-ō, and due to it's connection to its master is immune to mind control. This Mochi Type Beast is able to mumble words such as mochi. It is strong enough that even high ranking entities such as Evil Lords and Pleiades would give pause. When defeated it leaves spoils in the form of pieces of edible mochi.
