I'm Not Happy About Picking Up a Busty Beast-Eared Loli

Because of my chuunibyo phase, I spent ten years doing so many things I can hardly believe myself. In the end, I became a hero of the Republic, admired by all, and the incredibly boring (but ridiculously awesome) Hero. In reality, all I do is sit around while people pay their respects to me. This can't go on! It's no different from being in prison! (Actually, there's quite a big difference.) So I decided to retire (run away)... But just after disguising myself and crossing into another country, I found that the whole country had already gone under without my knowing. And the beast-eared, busty little girl I picked up by chance turned out to be that country's princess...
