Cagliostro is the founder of Alchemy in Granblue's world. Was originally born very sickly (and male) and eventually made alchemy as a "fuck you" to life so she wouldn't die young, and just kept working on making her body more and more to her tastes over millenia. Can't swim (not relevant but something we learned with the release of her summer version).
Not relevant to this story but there's a great Cross fate episode between her and Ladiva (the other trans character I know of in GBF)
Charlotta's the captain of the Lumiel knights and her fate episodes are basically all following the fact that she's super awesome and chivalrous but doesn't like people thinking she's a child so she wants to get taller so they stop, she's a harvin and they generally gap out below 4 feet.There was one event about her trying to give up GBF's version of happy meals to appear more mature.
This does have a good point in that it would make sense for Charlotta to go to Cagliostro for growth potions... or considering how often she offers it to people (Deliford, Ladiva, etc.) A new body... though she only offers cute girl bodies even to Deliford who's a husband and I think father and like 40 or something? So she might not be willing to aim for height... I dunno sorry for the rambling.
