First of all, thank you to RokkumanRaito for the bounty sponsorship.
The trigger words for this LoRA are: Felicia, Midori, Nakagami Takashi style.
The training primarily focused on these two characters, with limited素材 for other characters. The artwork turned out really well.

If you don't want to create black and white images, and instead prefer colorful images of Felicia, add these two prompts: blue hair and blue eyes.
For other characters, if you want to create colorful images, adjust the colors accordingly based on the desired color scheme for the character.
