I don't have any idea what font to use, but my suggestion would be to skip the font all together. Thin lines on thin skin can be prone to blowouts and you're looking at your wrist and elbow ditch - not a great place for that. If you absolutely must have the font, I'd ask your artist to find something - he's the one that will have to make it work.
So I’m planning to tattoo this design I made on my forearm(as in the attached image-about 18x6 cm)
But something that I was wondering about was the font to use with the Japanese letters, as they are going to be quite small my tattoo artist advised me that we should find a font that’s less like brush strokes
so my question is if somebody has an idea for a font which would fit the overall theme but will not fade badly and will be more easily tattooed
P.S I know that zoro and ichigos panels are not very good for a tattoo as the lines would fade to make it look incoherent, this is something I already talked to my tattoo artist about and he will design it better by hand
