Mamono ('''魔物''') is a [[Languages|Youkai-go]] term which means "evil spirit". It is a category of creatures that have appeared in the Mazes alongside [[youkai]], which possess a range of magical abilities and traits. Whereas youkai are sapient, civilized creatures that have integrated into society and communities, mamono are feral monsters residing in the Uncivilized Area, being one more category of dangerous creatures that can be found there.
Akaname is a Youkai-go term which can be transliterated translated to "filth licker" or "grime eater".
The akaname is a short humanoid creature, usually no taller than 4 feet. Though they can stand upright, they usually walk on all fours, crawling along the ground in search of trash and garbage, which it seems to have the ability to eat and digest. Despite their voracious appetite, they always seem to maintain a lithe, almost skeletal appearance, with an average weight of 50 to 60 pounds. The most distinctive trait of an akaname, however, is its stench; they are foul-smelling creatures, who seem to only enjoy themselves in filthy, putrid environments and pungent smells.
