I wonder how much advance notice the author had; this is actually a pretty solid ending for an axe, to the point it would have worked for an extended one-shot/single-volume series.
On top of that, the good ending for Frog Girl... given the prospensity for the holy-on-a-pedestal-virgin that Japan seems to have a thing for, we've got a married(?) mother who ran away after the guy got a royal beatdown for his abusiveness...
