Tattoo parlor

You! Yes you! You were isekaid into this really generic fantasy world, but you used to be a tattoo artist, so you decided to open a tattoo parlor to spice the world up, and with all the magic in this world, tattoos have become even more interesting. So you used a mana stone and used it as a battery and made a Tattoo pen. Now, your the worlds first and only tattoo parlor.

So, to be fair, there is many items to use in tattoo products for this so I'll Make a quick list here. Without further ado, let's go.

Kraken Ink: The most basic ink, it's black, and holds to any lighter tone of skin easily. Moves slightly like oil in water under the skin Fairy dust ink: a golden ink, it glows in the dark and holds to any skin tone. Dragonblood ink: a red ink. Holds to skin well for lighter skin tones. At the start of the tattoo, it glows blue like flames, and going up, it glows red and orange like fire. Unicorn horn ink: a perlescent white with rainbow iridescent ink. Gives the tattoo a soft heavenly glow. Sticks to darker skin tones better. Mermaid scale ink: a light blue and teal ink. It sticks to lighter skin tones well. Looks more vibrant when wet. Etc... many more inks.

Eldria. Your boring typical fantasy world. The only thing unique about it is that people from our world are constantly transported there. Causing the world to be affected and it's culture to change. People from earth are constantly using their knowledge or skills for profit in their new lives.
