Check out my AI-Manga creation using this in this article: (https://civitai.com/articles/13222)

Model is very versatile : For Non-Manga traditional images , add "text","speech bubbles" , "words" in the negative prompts and remove "manga art style/single panel,etc"

Works well with these 3 models as base models : WAI-NSFW-illustrious-SDXL V12.0 (https://civitai.com/models/827184/wai-nsfw-illustrious-sdxl) , Prefect IllustriousXL (https://civitai.com/models/1224788/prefect-illustrious-xl) , Animij V2 (https://civitai.com/models/1353314/animij) and Default illustrious-SDXL Base version . Adding this Vixon-Ghibli (https://civitai.com/models/1416735?modelVersionId=1601308) seems to give smoother simpler images

Lora weight = 0.6-0.9 Seems to work well for me , with 0.8 and 0.7 being best and some slight variations depending on the prompts . Recommended cfg = 6-8

Try to keep the negative prompts minimal . In the positive prompts : First add some beautifiers/modifiers , then the general scene setting and finally the character specific trigger words for enhanced experience ! (Eg : manga art style , black and white/nothing , single panel/multiple panels + masterpiece, best quality, amazing quality, very aesthetic, absurdres, highres, anime coloring + indoors , classroom , windows open , 1girl , solo , standing , looking at viewer , one eye closed + school uniform , brown hair , long hair , purple eyes , etc)

You can also insert any characters of your choice by using another Character LoRA !
