Motoko Aoyama aka. the Kendo Girl (Love Hina)

Trained on Anything V3 using cherry picked pictures from the Love Hina Anime adaptation (aired in 2000).

Gettings pretty good results with a default weight of 1, and then going to 0.8 (more liberty on outfits) or to 1.2 (better looking face and fidelity of the character). Adding kendo training and shinai keywords in prompt helps to get her with the kendo outfit and a fighting pose.

As training pictures are only from the anime adaptation, you will also have a high chance to get the same "2000 anime style feeling".
