The artstyle used by Satoshi Urushihara in the illustration artbook "Naburu".
Recommended settings: Hoshino v2 at 0.7 or lower.
The original artbook has many images with dark elements as background. The LoRa sometimes interprets that the whole generated image has to be toned down. Increase the CFG scale to mitigate that. At least 3 is recommended to not have darkened images.
