1. What is the procedure of the Volume release here?
When I release a new volume, it will be on the Hataraku Maou-sama page on this site. I will also add a blog post to announce it. The newly released volume will only be on my site for one week, after which it will be removed and you would have to find it at the Hataraku Maou-sama Discord server when it is released there. There will be a password hint given in which you have to solve it.

The password hint will be in the general format of xxxxxx1234567890 where the ‘x’s will be a character’s name, which is all in lower case letters and the string of numbers is the ISBN10 number of the Japanese volume (there is no book with the ISBN10 number of 1234567890, please don’t be idiotic and copy that as the password), which you can easily find on the Hataraku Maou-sama! wikia.

2. I downloaded the file but I can’t extract it with the password.
If you’re on a phone, switch to PC. Not all mobile zip file extractors are password friendly. If you’re on PC, switch to 7-zip if you’re using winrar, because that can be quite iffy as well. Lastly, make sure you are actually inputting the correct password.

3. How can I get the Hataraku Maou-sama volumes if I have missed the one week period or I wish to get older volumes?  
You can join the Hataraku Maou-sama Discord server at this link https://discord.gg/vfBNHj6. Please register an account and read the Rules and FAQs on how to become a member. You can only download the files after becoming a member. Please do not upload them onto other sites.

Please take note that as of 1st January 2019, all the volumes released by Yen Press has been removed and every time Yen Press releases a new volume, that volume will also be removed from the Discord server.

4. Will you be translating Hataraku Maou-sama! Volume 21?
As mentioned, I translate from the Chinese version. As of now, the Chinese publishers have not announced the release date of Volume 21. If Yen Press manages to catch up and releases within a few months of the Chinese publishers, I will not translate Volume 21 at all since the official release is so close.

5. I just finished Season 1 of Hataraku Maou-sama!, where should I continue from the light novel/manga?
You can continue reading from Volume 3 of the light novel. As for the manga, start reading from around Volume 26.

6. Is there any recommended reading order for Hataraku Maou-sama! novels?
This is the preferred order:
1, 2, 2.8, 3, 4, 5, 5.5, 6, 7, 8, 9, 10, 11, 0, 12, 13, 14, 15, 16, 0-Ⅱ, 17…
It is also possible to read the series in its release order:
1, 2, 3, 4, 5, 6, 7, 8, 5.5, 9, 2.8, 10, 11, 0, 12, 13, 14, 15, 16, 0-Ⅱ, 17…
