>Deep in the seas of the faraway world in a liquid dimension, lies the Kingdom of Erid, known to be home of Prism, Shadow and Light Slimes. However, Light and Shadow slimes were at war with Prism Slimes, but the one who ended the war was Tiamat, or rather, her past selves - Yala, Jella, May, Neena, Olya, Gina, Miya and Kari. Eight different slimegirls of different descents have estabilished a new civilization in chaotic world of Erid, making the time of peace and prosperity.
All eight of her past selves have united their bodies, minds and souls to become as the gorgeous Empress of all Slimegirls - Tiamat.
