Erubetie

One of the Four Heavenly Knights, she is a slime monster. Called the Queen Slime, she is the most powerful of all the slime monsters. Able to divide and expand her body at will, her attacks are very unpredictable. She also seems to be capable of controlling water at will, using it to inflate her own body. She can even use her slime to make a person younger but can also take away that person's memories is so desires. In actuality, she is a colony of over 10,000 slime spirits and other monsters that are controlled by a single will. Most willingly fused with Erubetie, but there are some who were attacked and taken by force. She cannot technically be called a Slime monster any longer. Erubetie keeps control over the colony inside her with her iron will. When facing humans, she is filled with both anger and despair. At one point, she desired to live with humans in peace... But due to thousands of beings inside her, it may be that her personality has become quite confused.
