Utawarerumono: Itsuwari no Kamen

The only thing I can remember is coming to in the middle of an unfamiliar snowscape. Where that was or how I got there, I don't know. I couldn't even remember my own name. The memories just wouldn't come. I only had a moment, left at a loss, to ponder what to do — but fate seemed intent on furthering my misery as a giant, insect-like monster burst from the snow and ice to attack me. Naturally, I ran like hell. The creature cornered me anyway. That's when SHE appeared, as if from nowhere — the beautiful, mysterious girl who saved my life. She told me her name was Kuon. A beautiful, mysterious girl... ...with a tail and ears like a beast's.
