Reading this made me sick to my stomach. It's just so dark and inhumane. The absolute rush of shock I felt when Diana entered the room full of prisoners. It saddened me even more how those two girls still tried to keep each other alive and stay happy even in such a horrendous situation.
10/10 manga. Loved it. Also mikuni is such an adorable name. In my language we use "mekuri" to refer to cats.
