So if Rimuru we see in the anime is a slime, not a human, then how can we see him changing into a human? This is because of Rimuru’s unique skill, “Predator.” This skill allows Rimuru to absorb anything and transform into it.

In the series, Rimuru meets Shizu, another Japanese girl who has been transported to the same fantasy world during the world war time. They quickly became friends, but Shizu was dying due to a demon inside her named Ifrit. Rimuru helped her by defeating Ifrit and freed her from its control. However, Shizu’s life force was depleted too much and she knew she wouldn’t survive much longer. As her last wish, she asked Rimuru to absorb her so that she would not be absorbed by the world she hates.


Rimuru honored her request and absorbed her after her death. like that, he took on her appearance. After this event, Rimuru started using his human appearance for convenience, especially when visiting other nations and attending important meetings with different races. This transformation helped him interact more easily with others.
