Well it's not on HIS OWN back but his son's so the son can't see amd the father can and he got tattooed for no particular reason other than his father did it that's it( if I remember correctly). Anyways he doesn't care much about neither the gang nor the tattoo.
Also you gotta know what's password and what's not which depends on how well it blends, looking at the maze sort of design it might not go well with traditional Japanese style because that's done in colour mostly and that black pattern might just stand out because of anamoly on the design.
Honestly could've done a better job hiding it tho. Or just remember it lol.
Also if he were to do it in his own body than doing it in thighs or smth will be better
Also, it shouldn't matter what kind of design if the Tattoo Artist knows what he's doing. And you don't have to put actual numbers in the Tattoo. If you really want to get intricate, use original symbols in place of numbers. That way, it shouldn't matter what design or type of Tattoo it is. They can be in one little area or placed strategically throughout the Tattoo. I had a Tattoo that I got with my first Ex, on my lower back where the "Tramp Stamp" type of tat would be. When I ran away from her, I immediately got it covered up and put my Mother and Grandmother's names in the middle in the swoops and curves of the design. One would have to look closely and stare at my lower back and ass to see what it really is. LMAOOO.
Shoot. I'm so sorry for all the notifications. I'm answering according to the paragraphs and keep forgetting.
I also agree with hiding the codes better. If they are using numbers, you might as well just shout it to the Psycho Brother at that point. Having it there immediately reminded me of the TV show Prison Break and Michael's tattoo.
Oh so Can't remember passwords huh.
