hime's credit-card weapon line in the description is not a joke

okay the 'weapon: her father's credit card' line made me laugh before I even started - and then she actually opened with exactly that energy, spoiled, mean, immediately talking about herself. classic tsundere shape but the rich-daughter angle gives it a specific flavor instead of just being generic tsundere number four hundred. anyone know if the maid-dress framing actually comes up in how she acts, or is it mostly set dressing for the personality?
