I used a premade ust for the french version, I've just modified ALL the notes to fit Aiko's voicebank. it sounds correct for me, I don't think it's off-tuned.
If you ever move notes in a UST, you need to move them all by sets of 12 spaces at a time, otherwise the singing gets off-tune :C even if just by a little. 12 spaces on UTAU is a full octave.

I'm sorry but i don't understand well the lyrics... and it sounds like there's an english accent inside ^^
