Erubetie

Erubetie is the final of the Four Heavenly Knights that Luka encounters in the Monster Girl Quest universe. The queen of the slimes, Erubetie is embittered over human's polution of water, drastically reducing the slime population in the process. When she meets Luka, for the first time, she aims to kill him, unlike the other Heavenly Knights. Undine's intervention prevented this, however.
