Demon Slime

Demon Slime (魔粘性精神体) is the ultimate stage of evolution of Slimes. They evolve to this stage by awakening as a True Demon Lord during the Harvest Festival.

As a result of this evolution, all of the parameters have been greatly increased and the the ability to freely change between material and spiritual bodies has been gained.

Because there have been no other Slimes known to be capable of evolving into this form, Rimuru Tempest serves as the only example for a description.

Appearance
In the Slime form, the Demon Slime retains the same basic shape as it did previously. The mass increased and when moving at a quick pace, the Demon Slime glows golden. According to Rimuru, the Demon Slime form feels "more majestic" compared to the regular Slime form.

Intrinsic Skills
Rimuru obtained the following Intrinsic Skills after evolving into Demon Slime:
 * Black Flame-Thunder (黒炎雷)
 * Demon Lord's Haki (魔王覇気)
 * Enhanced Body Double (強化分身)
 * Infinite Regeneration (無限再生)
 * Magic Manipulation (魔力操作)
 * Multilayer Barrier (多重結界)
 * Spatial Motion (空間移動)
 * Universal Sense (万能感知)
