The following are helpful links to LN illustrations from a reliable source.
Volume 1: imgur.com/a/Yevs0
Volume 2: imgur.com/a/rNuY8
Volume 3: imgur.com/a/lA7ME
Volume 4: imgur.com/a/zuMeE
Volume 5: imgur.com/a/TZ057
I suggest we should upload those illustrations on respective volume pages like other light novel wikis did. It could draw more attention from readers.
That's a good proposal however wikia might consider this as a violation to their regulations.
On the side note, we can put a license to those images are part of non-commercial, share-alike attribute.
What do you think?
