Like other Hierarchical Cities, Wadatsumi was formed after the Dark War. The city itself had architecture more commonly seen in Japan, which was left uninhabitable after the Dark War itself. In the centre of the city was a large pagoda, the Wadatsumi Castle. During the Ikaruga Civil War, Wadatsumi was the last city to fall to the Novus Orbis Librarium, serving as a final bastion for the Ikaruga Federation and Tenjo Amanohokosaka. The city was burned to the ground and all citizens were killed or evacuated.
Since the war, the ruins of Wadatsumi served as a testament to the NOL's strength and no efforts were spared to its restoration, unlike other other cities such as the 6th Hierarchical City of Yabiko. Underneath the Wadatsumi Castle rested Kushinada's Lynchpin. Relius Clover, alongside Carl Clover, Litchi Faye-Ling, and Nu-13, battled for this artefact within the city's underground against Izayoi, Makoto Nanaya, Bang Shishigami, Noel Vermillion, Ragna the Bloodedge, and Valkenhayn R. Hellsing.
Because Kokonoe was born in Wadatsumi, it can be assumed that the city was one of the first built after the Dark War.
