Toda speaks surprisingly good French and is the semi-official voice actress for any role Jodie Foster played.
Interestingly enough, she dubbed over for Tanya Roberts as Julie Rogers in the Japanese dub of the 70's Charlie's Angels series, a series that a certain anime that she's well known for voicing in is often compared to.
