I am so sorry. I've been so busy that I totally missed that there was a new translator. My store has really gotten busy and its really taken a lot of my attention. I have updated the source links on the main page to reflect your new sources. Thanks for finding them!
About the pounds vs kilogram thing. The wikia is based on the English translations, so I need to stay true to what the translator has put and they used pounds. If the original Japanese used Kilogram I can make a note. The reference link is wrong anyways, it should be chapter 21.
The article title for Lightning Fire Divine Book needs to be changed back. The wikia is based on the English translations from Thyearia and they use "Book of Divine Lightning Fire." If there is a different wording it can be listed as a name variant, but the main title needs to be based off the light novel translations.
