This cube craft paper toy is the Spider Queen, the Boss of Tsuta Ruins, Amaterasu falls into her trap after using Vine on some Konohana Blossoms, from the video game Okami, the papercraft created by scarykurt.
The Spider is based on the Jorōgumo, a creature from Japanese folklore. Although there are many tales about this creature they all have the same basic story. The Jorōgumo is a spider that is able to take the form of a beautiful woman who uses her looks to seduce a man. When the man has bee seduced the Jorōgumo then traps and eats him.
As Amaterasu meets her so early in the game, she is an easier boss. Slightly stronger enemies appear later on in the game that share a resemblance to her, these are known as Bandit Spiders.
