Here's Kuriko Kazetsubaki, another quality old school Waifu. I'll be honest, her hair is a mess and a gacha to generate. It is not terrible but SD really struggles with her twin drill-like antenna. Otherwise about this series I can only say Yuna and Rin are a bit crap waifu wise and i only liked her and maybe the doctor's crazy little sister.
Regardless, seems to work fine with: <lora:kazetsubaki_kurikoV5:0.8> kazetsubaki_kuriko
The style seems to be rather baked in as there's almost zero fanart and this is trained almost exclusively with the tv series.
Only a single outfit was truly viable, she uses a couple in the series but they are not really special enough nor worn enough to make them viable. So I only explicitly trained her uniform:
white_shirt_blue_puffy_short_sleeves_pink_ascot_blue_brooch_black_corset_blue_pleated_skirt_garter_straps_thigh_strap_black_thighhighs
As I mentioned this is strictly trained on screencaps thus i will only add the tag summary so people can experiment.
