The teacher, Natsukawa Machiko from Panty Flash Teacher. Character requested by another user.

I went through quite a few iterations of training and nothing seemed to prompt really well but in the end I tried something different and seems to give some decent results.

Use green_eyes as a tag in the positive prompt. I usually use 0.8 weights for all my images + highres fix with 0.5 denoise.

Shouko Asada from the same series is coming tomorrow, I just don't have enough time today because of work.
