I no good at Internet.

The standard response is here.

Volume 5 has been released in Japan, 9/25/2024.
That's after JNC did the initial license negotiations, so it'll be a newish discussion with Overlap (the Japanese publisher.)
JNC is very good about keeping a series going, but they very rarely say anything prior to announcing that pre-publication posting will commence.
