Takina from Lycoris Recoil, wearing her standard 2nd class uniform.
The uniform itself was modeled in Blender, while the rest of the model was made in VRoid Studio. I've recently remade her hair to match the actual design a bit more (the old version looked terrible lol). The new hair is also free to download on BOOTH in case you want to make something with it too!
