Ivory Tower appears at the second meeting of the Pure-Colored Kings in place of White Cosmos, and does so in a way that renders him nearly undetectable, even to the Kings assembled there. They introduce themselves very plainly.
At the third meeting, when Silver Crow is confirmed to not have the Calamity Armor in his possession anymore, Tower briefly attempts to ascertain the location of where Crow hid it, but is quickly cut off by Black Lotus.
Ivory Tower has a slender, ivory-colored figure and a simple armor design, and doesn't appear to carry any weapons. Their head, however, is tall and pointed, and there is a parting line on it, but no eyes or mouth can be made out.
Ivory Tower has never been depicted in full, so their appearance is unknown save for a diamond-shaped, pointed head with a slit for glowing white eyes (there might only be one eye). There also appears to be a golden insignia above the eye slit.
- Under Cover - An Ability that presumably allows him to conceal his presence in some way.
