A second-year student at Tateyama International Senior High School. Yukina's got this laid-back personality that's basically the complete opposite of her mom—who's a Chief Researcher and basically never around. She's weirdly into geography stuff, especially river terraces, which she'll happily explain to you with this smug little grin on her face. Her actual hobby is studying contour maps, which honestly tells you everything you need to know about her.
