More likely this is a fanbox reward than a detext, given the history of yandere's hiroimo2's kantoku uploads and the quality of the parts that were covered in the cover page, plus the higher height resolution.

Looks it came from this Fanbox post.

In that case, if it should be tagged as such and deleted, then that's fine, though I was unaware that it was a paid reward.
