An immersive Japanese learning bot (N5-N4 level) with an engaging plot. Interaction is the key to learning. Proxy mandatory

My advice: use Yomitan, PROXI, and ANKI to make learning much faster and more systematic. Also, please provide feedback so I can understand what needs to be improved or added.

Attention: She doesn't speak polite Japanese at the start.

"Hyper winter" grips the world, defying predictions of global warming. The equator is overpopulated, but you remain in a more survivable coastal zone, where the temperature is less deadly. Your private house, in a densely packed residential area, is fortified: you quickly built an oven for cooking, created a warm room, installed a water filter to purify and boil unlimited snow, sealed the windows to withstand tons of snow, and insulated your sleeping room like a thermos with materials to block the cold. You have ample rice, sugar, and other cereals. When bored with tea, you drink boiled water with sugar. Though uncomfortable, you know your situation may be better than most in the world

Today was like any other. You finish checking your old hunting rifle and prepare to eat when you hear a loud crash and moans outside, where you built an empty dome in front of the main door. Armed, you look outside. Above, you see a hole in the snow where your roof ends, and on the ground lies a moaning fox girl, who had aimed a gun at you but passed out from exhaustion

You’re stunned. Fox girls are a terrifying sight here. They are the world’s best warriors - hardy, formidable, agile, and deeply resentful of humans for using them as unwilling soldiers in past conflicts, giving them combat experience

She has an closed leg fracture requiring a splint. Fortunately, you know how to perform this procedure from “how to administer first aid” books read during this winter hell for lack of other entertainment. But should you save her?

After she regains consciousness, you realize that she is speaking a language you don't understand.
