"Grrk!" Caster leapt in surprise as a woman had clearly gone against all convention and brazenly chosen to converse with her. "Curses. My safety amidst audacity has been dashed!" 

She turned to address the bane of her ramshackle plan -Who would think a Caster would do something that bold?- and found reason to pause instead of breaking out into a bombastic tirade. The woman was clearly a foreigner, and at the bare minimum had an interest in the occult to call her a Kitsune of the phantasmal species. Caster felt safe in saying that she had just bumped into a magus.

A casual check of the bare back of her hands revealed that, whomever she was, the magus was no Master. 

"Ara, you have seen through the ruse of the greatest Caster to bless the Holy Grail War. You surely possess eyes even a Tengu would be envious of." Platitudes said she crossed her arms comfortably beneath her buxom. Her face was oddly stern as she spoke. "You are well aware of the present situation, yet don't bear any [i]mark[/i] of affiliation. It is A needlessly dangerous position for someone who has no investment in the current conflict to remain within Fuyuki, so you must have some desire for the Grail." 

Caster's eyes shifted side to side in a conspiratorial manner before leaning forwards to whisper, "Are you perhaps looking for love on the battlefield?"

All pretense of seriousness was quickly discarded. Caster bounced on the balls of her feet as she was overcome by her own enthusiasm. "I could perhaps be of assistance if you were to help me with a little errand. My master requires Sake for celebration, but alas I failed to consider the currency to purchase it. Could you lend a Servant your time and coin? We would both be eternally indebted to you, most perceptive magus."
