Sorry for the untranslated (or even romanized) title-- I can't make heads or tails on how to even translate it, given my limited knowledge of the language (Google Translate auto-detects it as Chinese for some reason).
It's yet another short chapter. Usually this artist's stories have a predictable progression-- heroine gets defeated, raped, occasionally mind-broken, then time rewinds so that she defeats her opponent, turning those events into a "what if scenario". So far, this last arc has bucked that trend, as the rewind part hasn't happened yet.
I don't know if the artist got too busy--the first part of Ch. 28 came out 3 years ago, the second part last year, and this one a few months ago (sorry for the delayed upload)--ran out of ideas, or maybe his interest or motivation waned. It's entirely possible that he intended this arc to be the last, with the heroine well and truly mind-broken; then again, he has yet to release the "kouhen" or concluding part of this chapter. Here's hoping he does soon.
