Thanks for your work.
I noticed a little error, on page 23 in the bottom right panel, there is a repetition of the word "only", the first use is correct (at least as far as my knowledge of English's grammatical norms goes) but the second instance is redundant.
Clevatess really taking seriously the idea of rising Luna, with the revelation that he may not be the only devil king meddling with humanity possibilities are starting to show.
By the cover of volume 7, it seems magnet girl has been permanently and unceremoniously recruited by Clevatess and... maybe she is having a good life, she is smiling in the cover.
