One short update: On NU the series has been labeled as having gone on a hiatus at 277 raw chapters. The author wanted to get some time to work on his new novel (a story about a class being transferred to a different world). According to his most recent postings, he has restarted writing DunBat, though.
The author also mentioned that DunBat’s getting a manga. Just a little heads-up~
