After the colosseum fight, she admitted defeat to Rou and got recruited by him as a possible war potential.
Due to her experience meeting many people in her travels and because she had briefly done a similair role in her original world, she was given the title of "Royal Capital Shop Manger" by Rou and made the General Manager of his store in the Royal Capital on day 190. She wasn't pleased with the job due to the stress of dealing with merchants and Nobles that were constantly trying to haggle the prices.
