The most recent LN volume was released in 2015. Since then, neither hide nor hare of any serialization (if my Google-fu is correct). However, along that same line, there hasn't been any announcement that the LN is over (again, if my Google-fu is correct, and if Wikipedia is to be believed). Ergo, the series is either on hiatus, ended at volume 11, or has quietly continued serialization, and hence my surprise that ponkan would tweet something related to it (if either of the first two are in fact the case).
UPDATE: LN vol. 12 is apparently coming out on September 20, 2017. Wonder what took so long.
