Slime Demoníaco

The Demon Slime (literally "demonic viscous spiritual body") is the ultimate stage of slime evolution, reached only by awakening as a True Demon Lord during the Harvest Festival. Because no other slime is known to have reached it, Rimuru Tempest stands as the sole example.

In slime form a demon slime looks much as before but with greater mass, sometimes glowing gold when moving quickly and feeling "more majestic" to Rimuru. As a divine being it can freely shift between material and spiritual bodies, possesses an immortal, ageless body, and wields power great enough to stand on equal footing with the True Dragons.
