Sucrose is an alchemist specializing in bio-alchemy, she also serves as the assistant to Albedo, the head alchemist of the Knights of Favonius. Noticing a trend of weight gain among Mondstadt women, Sucrose investigated the matter, however, her research had the opposite effect. Oversampling local food, and an increasing reliance on Albedo's tech has plumped the poor girl up over 400 pounds. It's rather embarrassing for her, but her scientific mind makes it difficult to make excuses for her size.
