FWIW:

Aiko 4 previews are a sticky in the Plat. Club Member's Only Forum by the name of "I {heart} Aiko (A4 PC Preview Thread)"

Whilst I'm still learning Chinese, the bottom-left character is the Chinese character for ai/love and the bottom-right is zǐ/child. Has Aiko become Chinese now?!?

Also, in terms of Traditional Chinese characters, the promo graphic literally reads I Love Love Child! Guess she'll still be problematic here in the galleries...
