Thanks for working on this, Sho Habby!
I assume the volume releases will resolve this complaint but I don't want to harp too much.
As stupid_chris mentioned, so far there aren’t any volume releases planned yet. If you want someone to license it physically, here are the most plausible culprits:
Viz Manga. They previously licensed Kubo, so it’s possible, though they didn’t jump on it this time. Still, that survey there is good if you want them to pick anything up you like.
Seven Seas. They pick all sorts of manga. I linked directly to their site, but every month they link a survey which allows you to suggest three manga and LNs you’d like them to pick up. They also do a giveaway where one random survey-submitter gets a free gift from them, and you get a coupon for their books on Bookwalker.
There’s also Yen Press, though according to their website they don’t have a survey in place - they keep an eye out for what’s popular. You can try emailing them anyway.
