Thank you for making Siren. Siren is the only one tool can rename multiple EPUB files by metadata.
I have some Japanese and Chinese EPUB files cannot be found metadata information because it has different file structure.

Siren can load "OEBPS/content.opf" but cannot load "item/standard.opf" for metadata information.
According to container.xml, there two different file structure.
container.xml


Because the publishers follow The Electronic Book Publishers Association of Japan and Digital Comic Association in japan.
