I don't really know either Sonic. Hell, you guys are the experts, so I'll leave it to you to figure it out who this person is exactly. Only input I wish to give is that:
Her name is "Rabu" in Japanese, spelt exactly the same, (in hiragana as opposed to katakana) and her measurements, including height are exactly the same as those listed on Tokyo Topless. Anyways, just sayin', no biggy.
