Arachne

Arachne are a special evolution of spider-type monsters. It is independent from the evolution tree. The Arachne is a medium sized spider monster that has the upper body of a human attached to the head of the spider body which acts as the lower body of the monster. The Arachne can see with all 10 of its eyes (two human eyes and 8 spider eyes) and can use the human body's arms for increased dexterity. The spider body is the same species as whatever the spider monster was when it evolved into the Arachne.

Monster File
A monster with no confirmed sightings in recorded history. As such, there is little to no information about it, and it is shrouded in mystery. It is said that the human part of the monster's body has the appearance of an exceptionally beautiful girl, but this is only a rumor, the truth of which is unknown. Because there are so few witnesses, it is questionable whether this monster even exists at all. The only sightings occurred during periods in which the Nightmare of the Labyrinth or a Nightmare's Vestige were also sighted, so it is thought that witnesses may have simply mistaken them for this creature. Because it's very existence is in doubt, it is impossible to measure the danger level of this monster.
