Nipasu

A female droid who was summoned by Berthier in episode 62. She was assigned with the task of corrupting the Soft Ice Cream Shop Bob Floy, an ice cream shop located on one of the Crystal Points of the future city of Crystal Tokyo, with Dark Power. She assumed human form, took over the establishment, and posed as a saleswoman there. However, the ice cream that Nipasu sold was designed to induce negative emotions and feelings of thermophobia in those who ate it, driving them to purchase and consume more of it.

Eventually, the consumers would end up being frozen within solid blocks of ice and stored in the large cold room at the back of the ice cream store, thereby contributing to the corruption of the Crystal Point with Dark Power. To attack, Nipasu emitted a blizzard of snow and ice from her mouth that was cold enough to freeze individuals in solid ice. Nipasu had dark green eyes and light blue-green hair.
