does anyone know when the next chapter of Mahou Tsukai no Yome will be out?

Apparently, it's been licensed so it's been dropped.

How will I be able to read it now then? Would it be in stores somehow ?

What does a license do

I looked at the scanlation team's website, and it says that a publisher called Seven Seas licensed it.

Basically, a publisher have the rights to translate it to a certain language. It's an official translation, so a lot of scanlation teams drop the projects to get people to purchase the books themselves to help support the author.

If you click on each volume, they give a list of retailers that might have it in stock.
