How I did it
I used a tool called Style2Paints. It let’s you color line arts using AI. I used a lot of Human hints to fix a lot of the color problems that the initial painting has. I also used the colored cover of TenSura Vol. 5 as a Reference. The line art also comes from the Status Section of TenSura Vol. 5 and used the portrait from there and upscaled it with Waifu2x to get a higher resolution photo.
