I suggest using a weight of 0.9 or 1.

Activation word is hachikuji01 for the normal form and hachikuji02 for the adult form.

Finally got around to do Hachikuji, I couldn't find a Lora of the adult version, so that had to be fixed!
I'm pretty happy with the result, very flexible and the style is good, but I had to make some compromises with the outfits, nothing major, but it's not perfect.

Prompt:

Normal version, default outfit:

Some things that are not perfect and I couldn't fix are:

• The star \(symbol\) tag, makes her star pin appear, but it's not consistent.

• You can add bandaid, bandaid on knee, but the result is not very good, I really can't understand why.

hachikuji01, long hair, brown hair, red eyes, flat chest, twintails, hair ribbon, white hairband, school uniform, skirt, shirt, ribbon, green bracelet, white shirt, short sleeves, blue skirt, suspenders, suspender skirt, star \(symbol\)

Add bag, backpack, pink backpack for the backpack, it's not perfect, and needs some RNG, but I think it's pretty much impossible to get right consistently.

Adult version, Mayoi Jiangshi/Second season:

hachikuji02, long hair, brown hair, red eyes, ribbon, hair ribbon, green ribbon, aged up, adult, medum breasts, navel, belt, tank top, brown tank top, fingerless gloves, bandaid, gargo pants, blue cargo pants

You can add jacket on shoulders, green jacket for the jacket she wears in some shots.
