34-year-old Sienna was born in Australia and is a part of Lupita’s modeling group. She loves to show off her beautiful blue tongue, but she wanted to show it off in more ways that just being a talent. And thus she became a model! And when she saw that Lupita was finding a member to represent Australia or Oceania for her modeling group, she decided to join the modeling group right away! And when she’s modeling in her photoshoots, she especially loves to show off her tongue. She even has a younger brother who is the boyfriend of fellow model Tsukiko, the two being introduced to each other when she decided to introduce her family to the kitsune.
