Eliminating The Powerful Spawn!
-----
Kireina didn't waste time, summoning her [Soul Feasting Abyssal Caterpillar Jaws] and unleashing over ten thousand little caterpillars over the four pieces of the Spawn of Demiurgus. The tendrils that were trying to get back together were forcefully cut and eaten, the spectral, chaotic and aberration creatures Kireina summoned mercilessly feasted on both flesh and soul!
Even then, the spawn moved to the next best possible thing it could do, all four pieces quickly attempted to regrow into completely new entities! However, Kireina was not letting him do that, not at all.
She moved through space, distorting the dimensional membranes themselves and appearing above all regenerating pieces at once.
Her weapons and her armor suddenly fused together into a single, massive dark blue fist, overflowing with cosmic flames.
