Chia Chia Records Taiwan is a legit CD company with physical stores within Taiwan , same with 5music Taiwan
So yeah I think it's the real deal . I'm surprised something like this happen cos I never seen before
Then again I never order via Chia Chia Records Taiwan but they're reliable
The preorder links for DVD & Blu-ray on Chia Chia Records Taiwan's website
DVD , 2 DVDs

Blu-ray , 1 Blu-ray

What Chia Chia Records Taiwan listed is the Japan press . Taiwan press of Ayu's releases start with AVJ xxx , not AV
Also I never encounter a releases where the Taiwan press is released before the Japan press , if so that will be really odd
