Yen Press have licensed:
So I'm A Spider, So What?/Kumo Desu ga, Nani ka?
- Light novel version is ongoing with 5 volumes out at present. I'm not sure about the status of the web novel, but the last chapter was a month ago and the chapter numbers go up to 300 with various unnumbered chapters.
- Published under Kadokawa BOOKS (same label as Death March)
- Originally a web novel published on Shousetsuka ni Narou.
- This series ranked 3rd overall in the first tankobon/novels ranking in last year's Kono Light Novel ga Sugoi! booklet, and was first excluding the popular vote's ranks.
- The author said in an interview with Kono Light Novel ga Sugoi! that they were inspired to write the series after reading Tensei Shitara Slime Datta Ken (below)
- No release date yet.
Regarding Reincarnated as Slime/Tensei Shitara Slime Datta Ken
- Light novel version ongoing with 10 volumes, web novel finished with 10 volumes having been wound up quickly after the series got picked up for professional release.
- Published under GC Novels, a relatively small label for whom this series is basically their only hit.
- Originally a web novel published on Shousetsuka ni Narou, this series is arguably the one that started the trend for weird reincarnations on that site (see above).
- Probably the series that has seen the fastest growth in light novel sales in Japan in recent years without the aid of an anime or live action adaptation.
- Indeed it is now the best selling light novel in Japan by an author who has never seen an anime or live action adaptation of any of their works.
- No release date yet.
The Saga of Evil Tanya/Youjo Senki
- Ongoing series with 7 volumes out at present.
- Published under ENTERBRAIN (Overlord, Log Horizon).
- Originally a web novel published on Arcadia.
- Received an anime adaptation in Winter 2017 (although I've heard the anime deviates quite far from the novels towards the end).
- Volume 1 pencilled in for release in November, but it seems to be somewhat unofficial at the moment.
