"A male raccoon that specializes in enchanting people. It has massive genitals, about 12 feet squared, which it uses to fool people. It sometimes covers itself in them and transforms, while other times using them as an umbrella. In the sake breweries of Nada, Japan, they say you can't make good liquor if there's no Mamedanuki around."
—Shin Megami Tensei: Strange Journey Compendium
Mamedanuki is a common Enemy Scan demon in Sector Antlia and Sector Bootes. Halphas offers to conduct a Mamedanuki hunt across Mitra's Tower in an EX Mission. While not a particular threat by itself, as an enemy it has access to the Macca Beam skill, which permanently removes a sizeable portion of Macca from the protagonist's reserves.
