I can't confirm if the catalog numbers are written on the release (not many pictures online) but it should be:
AN-0001
https://vgmdb.net/album/92669
AN-0002
https://vgmdb.net/album/94586
AN-0003
https://vgmdb.net/album/94587
The JAN codes are sequential:
4582528393964
4582528393971
4582528393988
If AN-0004 is 4582528393995 and AN-0005 is 4582528394008, then that's probably confirmation.
