数学ガール フェルマーの最終定理 ; Mathematical Girl - Fermat's Last Theorem

I love math. Just after the high school entrance ceremony, I meet a beautiful girl: Milka. Milka is a mathematical genius. She gives me many math problems, she shows me many elegant solutions. Milka and I spend a long time by discussing math in the school library. One year later, I meet another mathematical girl: Tetra. Tetra is one year younger than me, and asks me to teach her math. While I teach her, she begins to understand math and to love its elegance gradually.
