Silbarrel Silbarella

About
Silbarrel Silbarella is an individual originally from the Free Cities Alliance, working as the chief of dorms of Happiness Pharmaceutical. Her ugliness is legendary and she is actually pretty infamous for it. Rance considers her his greatest foe, due to the great fear it inspires on him to just look at her.

In Rance VI while fighting Sieg, who was reading Rance's party minds to transform into beings that they feared the most, Rance immediately thought of her, which demonstrate the fear that he has of her.

In Rance Quest, she became the leader of Lion Mind after Alkanese left the group, renaming it to "Cheetah Mind". Crook determined that her ugliness was so great that she could potentially destabilize the System due to the impact she causes on other people/due to the danger of her genes spreading out, deeming her as a Balance Breaker and sealing her as a result.

She is freed during the events of Rance X.

In the year RA0009, the Neo-Twelve Knights utilized the great power of the mysterious creature SBR to distract Rance, before Reset was able to hit him with Hand of Klausen and restore his sanity. It's assumed that SBR is actually a (joking) reference to Silbarrel.
