Another manga with ending "just end like that?" ahhh moment
it's the end broskiit literally just said volume 3 end, that doesn't mean the thing is over tho
so in short the hole thing is a dud, cause the author stopped caring.for those curious what happen next, you can check the WN here: https://ncode.syosetu.com/n1720gr/
it seems some change is made in the manga compared to the WN
the manga should be finished around chapter 48, but compared to the WN there's some difference in the fight, like in the WN that orikura girl also participated in the fight
if curious what happened to former mc party member, it seems they got brainwashed and become part of the demon army and attack mc later
the latest chapter involve fight between mc and the priestess girl, he succeed in defeating and recovering her at least, tough the WN become hiatus after that
