Software Translation:
Artist Shirotsubaki's style lora. He liked Idolmaster, he drew Idolmaster girl's picture. I liked Idolmaster, I made his style's lora.
That's all.
The trigger word is shirotsubaki, which I didn't use at all as shown in the example image. But in case the pony series somehow appears to be furry , or some other style, using the trigger word helps to restore the artist's style.
