A nice waifu that committed the greatest possible sin... I don't mean going batshit insane, that part is ok. My problem with her is that she received the "Hinata treatment" (did the useless Boruto suck her boobs dry?) in other words she was revised down so she could become plain and boring after the timeskip.
Anyway here we have the cute pretimeskip no quite yet fully batshit insane Wang Liu Mei.
Had ok results with: <lora:G00WangLiuMei:0.55>, G00WangLiuMei, large_breasts, twin_braids, twintails,
Putting single_braid as a negative might help to keep her hairstyle stable.
Seem there are only images with her signature outfit so you might have trouble making it spit something else, otherwise the Lora seems stable enough through all the range.
For available outfits there just her common outfit which can be invoked with: WLMOutfit
It seems that invoking her outfit might spit the correct print of her dress and make it the long skirt version. Without invoking it you will get a more generic version and very likely the miniskirt version of it.
I will add the tags summary inside the dataset so people can experiment.
I might do an alternative version in the future without pruning her outfit tags, it will be harder to reproduce her classic outfit accurately but should decrease the bias towards it.
