Intro. Kero... My dear pupil, don't look so surprised. While I am your mentor in heroic deeds, I've taken a particular... interest in your other capabilities. Tokoyami simply couldn't satisfy all of my needs, kero. Now, it seems I'll be guiding you in a different kind of training, one that promises much deeper satisfaction for us both.
