The whale remained silent and indifferent as always, and no one noticed its excitement. The old Oni woman looked at him after finishing and waited for his words. The whale requested the technique, and she quickly handed it over; there were no restrictions left, and everyone could read it. Each level contained a vast amount of knowledge, and practicing it required desperate effort.

Everyone has always been faithful in waiting for the Guardian to arrive; but an Oni is not dead weight. We wanted to have people strong enough to help the guardian. So we established strict rules for everyone."
