We are back on air after some exam-induced delays from my own part, but since I'm on break this week expect 130 to hopefully come out soon.
While I've unfortunately lost the color pages for this chapter, I did manage to recover the scan I had made 5 years ago (time sure flies!) of the extra commemoration page made for Kill Me Baby's 10th anniversary from the July 2018 issue of Kirara Carat, which was the same issue Chapter 129 was serialized on.
On page 5, that's not a revolver. Just calling it a gun might be better.
Yeah, it does look like a longer gun after all. Should be fixed on the volume release alongside a lot of redrawing improvements.
