This is a fan work based on the anime Girls und Panzer (an official prequel?). It mainly tells the story of the protagonist, Miho Nishizumi, competing in a tankery tournament last year at Kuromorimine Girls' Academy. I'm no military expert, and my main focus is on character design. I've drawn on scenes from the previous tournament shown in the anime, as well as the manga Girls und Panzer: Little Army. Please point out any details that don't fit.
Feel free to read the story, offer suggestions, write reviews, or leave whatever comments you like. The author definitely won't... ahem... get angry.
(Gradually expanding. It's been serialized on Qidian and 17K for a long time; I've moved it over here.)
