Koa did his best to sink his teeth in hard, out of respect for her, even if it wouldn't do much to harm her, given the way familiars were built. He felt her jaws dig into his flank, and felt a stab of pain, though it was nothing compared to what they'd fought. Her bite was strong, that much he could feel.
After a moment longer he finally released and drew back. "You're strong! Really strong!" he declared. He wasn't sure if it was a Tyrunt thing or not, but he felt like he understood her better now. A thought occured to him, and he took out his badge and texted a quick message before putting it away.
"Rascal, my Tyrunt back home, would love you."
