I would advise to not use latex for this(from what I found on google, I haven't seen the anime).
You need to cover a good deal of skin, and latex is not breathable at all. I advise against using anything non breathable as a body paint. If it seals your pores, its it not healthy to cover large areas of skin for long periods of time. You skin can't breath and cant sweat, if its warm out someone could pass out, especially if you are wearing wigs too. Not to mention how painful it is to get latex out of the little baby hairs that cover your body, even with remover.
You can still get the same effect out of the water or alcohol based body paints. You may have to touch them up a few times during the day, but your skin will be very happy about it. Kryolan aquacolors have good coverage for a good price, but if you really want to durability and have it not transfer to objects that are handled look into skin illustrators, or temptu professional colors. They are alcohol based paints, and they stay on really well. They are on the pricey side, but no more then colored liquid latex. They are marketed to be done with an airbrush, but you can get an even coverage with a seas sponge as well.
