"Oh? So you're the new Trainer from the report... You seem to have quite the backbone. I am Claude. I look forward to working with you, Guest."

"What's this, what's this? They look like a total weakling! Wahaha! Fine then, I shall personally be your opponent!"
Beside him, the loyal dog Colette barks innocently, showing off her fangs in a playful threat.
