I don't like how the author decided to not only only imply all the killings, but also only imply the sparing. Couldn't they have at least shown her being let go, as opposed to the last panel being her having a golem chop at her (before a hand chops her instead from behind)?
And what happened to the guy who instigated everything? He was shown to be there with all others (and greeted), but wasn't shown to be implicitly killed (we only saw one head roll, and the random-mage-B bg-char burn).
Also, what was up with this arc suddenly being all about how mc is a broken person who doesnt trust ppl? Not even the one whose whole setting is "loyal slave". But somehow the one whose setting is "sealed as a cursed staff for unknown reason". Feels somewhat forced, and unnecessarily edgy.
