Monsterpedia Entry
''“An indigenous monster to the Yamatai Region. Apart from their extremely long tongues, they are very human-like. Black Alice endowed them with extra physical strength, drastically increasing their combat abilities. Although their intelligence isn’t too low, they are sometimes teased and ridiculed for their happy-go-lucky attitude when it comes to licking any man they can. They seem to have gotten involved in the current situation without really knowing what was going on.

Loving human sweat, semen, and any dirt on a human’s body, when they find suitable prey they will continue licking them clean. Their long tongues are quickly able to send any man in the throes of agonized pleasure. They won’t ever lick their prey to death, but the intense sessions can leave men unable to stand for days. If attacked by a group of Akaname, they will take turns licking their prey until he is completely dry.”''

Trivia

 * The akaname (垢嘗?) is a demon or yōkai from Japanese folklore. Meaning filth licker in Japanese, akaname can also be translated to mean red licker since aka is an homonym for red and filth. For this reason the akaname is often described as being red in color. The akaname is the “personification of the fear of using a dark bathroom late at night.” It is said to come out at night to literally lick up the grime and dirt that accumulates in unclean bathrooms.
