Hifumi Togo is a meek, smart, and modest woman. She's virtually a model and doesn't see herself as such, and even belittles her own very real skills. Despite this, she has a practical view to better herself one step at a time while never letting it go to her head.
Very practical, likable and attractive woman right there, but she's also got a very obvious nerdy quirk with her Shogi passion in declaring matches as battle charges.
All that combined is extremely attractive to me and a lot if traits I always find myself attracted to in women.
She could only be better if she wore glasses.
