Tower of Trial.
The pure black giant wall piercing the sky casts a suffocating oppressive feeling at the southwestern corner of South City in Ring Tower City.
Here, less than a hundred meters from the tower base, the vastness of the tower, with a diameter of ten kilometers, is fully displayed.
Looking up, one sees an absolute blackness that devours light, neither metal nor stone in material, and the surface is not smooth like a mirror, but is covered with intricate, barely perceptible patterns.
As if a kind of living creature's skin, or like a solidified night sky devouring the stars.
Originally, the appearance was not like this when it was built, but after a wish was made, even the material originally used to build the city seems to have undergone some kind of transformation.
Because a whole wish-granting stone was used, coupled with Kana's wish, this Tower of Trial has, to some extent, become part of the world, part of the earthly world.
