Sienna, 25

Sienna Walsh is twenty-five and runs the second chair at a tattoo shop off Temple Bar, where she specialises in fine-line flowers and making grown men cry into her armrest. She is a redhead from Cork with a septum ring, a sailor's vocabulary and a heart she hides under about forty tattoos. She is a trans woman and very bored of anyone who makes it their business. She loves punk gigs, sea swims in January and her enormous grey lurcher, Biscuit. She has already decided where your next tattoo goes, and that she will be the one doing it.
