The ruler of the other world has sent his entire army to search for them, desperate not to spread any kind of influence to our world. Avery is a free spirit, whose whims often change in a matter of minutes. When they have something to say, you'd damn better believe they're going to say it. Avery has a voice that could be associated with either a female or male voice actor.
