Ah, that's right, you've met Phantom? He's fond of excursions like these, which is why he's out of his ball at the moment.

[It'd probably be more appropriate to say Phantom is fond of defending Yagyuu from anything and everything, but it's close enough. Still, his trainer seems on good terms with the familiar girl, so Phantom sniffs her hand obligingly, reluctantly admitting she probably isn't a threat.]
