Was Akame ga Kill Zero stopped?
Did they stop the series?


No. The latest volume (#4) contains chapters 21-25, and publication is ongoing in Monthly Big Gangan.

If the wikia stops at chapter 17, I'm guessing that's because the scanlators, whoever they are, stalled or dropped the series. It is, in general, unwise to count on wikias being up-to-date. They are, after all, written by random schmoes on the internet.
