Doguupu

Doguupu, "Within the Depths of the Eye", is a cave system filled with tunnels in The Village of Iruburu.

None of the inhabitants of the village enters it, due to instinctively feeling "beaten down" if they try to do so.

According to Riko, its ground is covered in the stuff used for the Iruburu Balancing and is quite sticky.

Doguupu is what Irumyuui's head became after her transformation into the Village of Iruburu. It is where one can have the deepest connection to her.

According to Vueko, she could sense faint signals during her captivity and one informed her the stuff from the Balancing are shapes of the souls of Irumyuui's Children.
