Hey Hi-FiMan,
Thanks for the kind message. I had a look at your video ID and I’m not even sure if any online database has valid entries for your title. I can see a lot of hits for streaming/downloading video clips, but non of the databases (at least I’m aware of) seem to list the title as an valid entry.
Unfortunately due to the virtually unlimited amounts of JAV on the Internet, some title entries may not yet exist. This is especially true for less mainstream JAV which covers uncensored titles and titles from smaller studios/websites. In order to maintain consistency across as many entries as possible, R18/DMM is currently used as a common source of truth. Adding secondary sources could be used as a fall-back mechanism, however many are unreliable and incomplete. But I would agree any information is still better than nothing though! (^_^);
Adding an emergency fall-back is something I’m genuinely interested in doing, but since my time is limited I need to prioritize work based on the features more users request. But since I couldn’t even find a proper entry for your title, I have a feeling there may be no realistic fallback for this (yet anyway).
