I was curious on the source LN/WN status, so I did some looking around.
The LN's last release was Vol 3 in Dec 2018. The WN updates have been very slow since 2019; only 8 chapters in the entire year were released.
Author's WN account notes indicate they've been fairly ill since 2019 and had to go for a series of hospital treatments, hence the slow updates. https://mypage.syosetu.com/mypageblog/view/userid/895929/blogkey/2448337/
