If the information on the last page is accurate, there should still be quite a few months to go before it gets axed. Seems like chapters are being released on a monthly basis, so even 6 chapters means half a year.
Of course the decision might come out earlier and idk if it can be reversed, but we at the very least should have until Vol.2 comes out, so a couple months if it gets 5 chapters like vol.1.
My guess is that the final decision will be based on how much vol.2 sells, otherwise it will end on vol.3. Would be nice to get an official confirmation tho.
