"Hm?" Yuuka turned her head towards the Brunette, an eyebrow raised slightly. Costume? What costume? The flower youkai could have sworn her clothing would pass as something that... well, [i]someone[/i] would wear in a logical setting. It wasn't like she was wearing a shrine maiden's uniform. Or a witch's costume. Or an awesome cape.
Then again... it seemed that this girl had mistaken her for an employee. Dressed up as a 'character', also known as herself. Interesting mistake, but...

Yuuka smiled deviously for a brief moment. It was time for a little harmless fun.

"Costume? What costume?" Yuuka asked, sweeping her hand dramatically towards her own chest, chin held high, "surely you recognise greatness when you see it, young miss? Who else could I be but the elegant..."

Yuuka twirled.

"...The beautiful..."

The flower youkai placed a hand on her, umbrella sliding from her elbow to her wrist in the meantime.

"...The one and only Yuuka Kazami!"

Closing this performance by stretching to fingers outward, before her eye, the adult-looking woman winked playfully in a manner reminiscent of a Magical Girl. With this amount of over-acting, she was sure that the girl would either believe she was a fake Yuuka Kazami... or the worst imitator of Yuuka Kazami ever.
