I have been doing a bit of snooping at the Japanese actors who voice the characters. Tart is voiced by Maria Kawamura, who voiced Usa Hime
in KNT. The actors for Pakarachi and Souffle are quite interesting, in some of the roles they played. Takashi Nagasako (Pakarachi) voiced Cervantes in the Soul Calibur series, as well as Big the Cat in Sonic X/Heroes.
Yuko Miyamura ( Souffle) really made my jaw drop, looking at some of her roles. Tillis in Burning Rangers (Never heard her Japanese voice, but that game was fantastic) Seung Mina in Soul Blade, and Chun Li in some of the Street Fighter Alpha games. And also in the Japanese version of Everyone Says I Love You, as the voiceover of Drew Barrymore.
