Ok Here he wave Keitaro's cute cousin. Probably the missing one from tolerable females characters of love hina, The others being Mutsumi, Kanako and Tsuruko.
I honestly hate love Hina outfits, not only are they mostly crap they are scarce. So basically for Haruka i just gave up.
Anyway this works fine with <lora:urashima_harukaV2:0.7> urashima_haruka,
To be honest she just uses different color aprons. In the dataset the most common ones are black_apron and yellow_apron. Other notable thing is that the smoking and cigarette tags appear a lot so thy might work. Wouldn't bet on it as the cigarette is small and i am not sure how well it is understood by 1.5.
No dataset for you as it is mostly manga and anime screencaps, instead it is just the tag summary so people can experiment.
