So I'm a Spider, So What? Wiki

Arachne is a Taratect subspecies with the upper body of a human and a spider for a lower body; what kind depends on what species it was before evolving. It is a special evolution available exclusively to small-to-medium sized Taratects that are at least level 50 and possess the Pride Skill.

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 its very existence is in doubt, it is impossible to measure the danger level of this monster.


Realizing it would be impossible to communicate with humans in her spider body, Kumoko makes her long-term goal to evolve into an Arachne, hoping that having a human torso might make her more appealing.

Powers & Abilities

The abilities of an Arachne appear to depend heavily on what species it was before evolving, the traits of which the spider half inherits. Overall, the evolution does not give any unique skills and merely offers an increase in stats. In fact, they might even lose some skills should they be incompatible with the body structure (Kumoko lost the Swim skill she had as a Zana Horowa).[1] However, in turn, an Arachne does possess some of humanity's unique traits through their human half, like being capable of speech and equipping items. Furthermore, having both a human and spider body gives it a unique field-of-vision and two brains, if one were to be destroyed the other can continue operating just fine.[2]

  • The species' name is a reference to Arachne from Greek mythology. Arachne was once a talented mortal weaver who proudly claimed to be a better artist than Athena, goddess of wisdom and crafts. They both challenged one another to a weaving competition, where Athena created a tapestry about the glory of the gods, while Arachne created one about the gods abusing their power and misleading mortals. Although both tapestries were exquisite, Athena was so enraged by Arachne's pride and her disrespect of the gods that she ripped the mortal's work to shreds and started beating her mercilessly. Consumed by shame, Arachne hanged herself, but Athena, out of pity, reincarnated the mortal as the world's first spider.
