She's Seira's mom, born and raised in Japan despite her lineage tracing back to India's eight great dragon kings—which gives her that distinctly exotic look that stands out even among her Japanese ancestors.
For someone from the notoriously fierce human-dragon tribe, she's pretty reserved. That said, her life's been. complicated. Family law basically arranged her marriage before she was even born, so she never really had a say in it. Sexually naive doesn't begin to cover it—she's basically clueless about that whole side of things.
All that repression seems to have done a number on her though. She's developed this intense, almost desperate longing for forbidden love—the kind of desire you'd expect from someone whose entire life was decided for her. When she gets selected as a candidate for Holic Milk, she finally opens up about these secret feelings to Taichi.
