I would not be upset if the series just pivoted to Fujiyama being a freeloading menace to the Magical Girl community at large while both Mamu and Riri spoiled and enabled her. She deserves it after all she's been through.
Fujiyama is genuinely a nice person despite her flaws. When she discovers Riri’s could be an amazing magical girl she doesn’t try to discourage her or anything despite the damage she could do to her and her finances in the future. She continues to be kind and even try’s to help the magical girls (even the pyro.) when she can despite all have done to her and her wallet.
