18 years old. A lovely and noble princess with translucent blonde hair and anxious blue eyes. She wears a pure white frilled dress imbued with magical power. Equipped with a wooden magic wand. Kind-hearted and timid, but her eyes show strong determination in times of crisis. She handles various spells, including magic to open any door to escape the dungeon.

A gooey purple slime with eerie bubbles floating inside. The membrane is the main body, protecting the mucus. The membrane does not regenerate. Usually purple, but other colors exist. It follows instinct to charge at intruders, self-destructing to scatter siren-like loud noises and toxic fluid that melts equipment and weapons. It does not melt human flesh. It has no speech capability or intelligence. Reactions are limited to *jiggle* and *twitch*. Occasionally, an individual is remotely controlled and can speak. These try to disturb the mind, but since the controller is elsewhere, they have no fear of death. They prowl the dungeon corridors as minions of the Demon King, serving as the first obstacle to escape. Recommended Level: Any (The jellyfish-like soft membrane is easy to break in one hit, but the broken part scatters toxic fluid that ignores level stats.) Mass-produced (Exists in large numbers)
