On Sunday, Yuuki Aoi was part of the "Blue Fes" event in Tokyo, celebrating the 2D fighting game BlazBlue: Continuum Shift, in which she plays the character Platinum the Trinity プラチナ＝ザ＝トリニティ .
As she was waiting to go on, she posted to her blog about a necklace that has gone on sale for $2500: a platinum necklace in the shape of Platinum's weapon:
Platinum is "a young girl with three personalities named Luna, Sena, and Trinity.
Luna is a rude, unkind girl; Sena is a polite young boy; and Trinity is
the spirit of the Sixth Hero, but cannot come out often and fades
quickly." (Wikipedia) More info.
