Oh shit starting the volume strong with a big fight
So i guess, judging by the cover, that the story will then focus on the boring honey traps later, and this is why Mankichi fell into low priority?
It is listed at 12 volumes for the deluxe edition and 20 for the bunkoban, so if it had an axed ending, this was probably the beginning of the end, which would suck given how Mankichi was a flagship manga that keep WSJ alive and afloat in the 70s, but then again it is Jump where no one is safe from getting axed
