Saw the twist villain coming a mile away and am gonna guess either deus ex machina will ressurect her or it was all just a dream.
Also expected protagonist to have a bit more grit when he found out she died when he already accepted the possibility of killing her, along with the fact that he watched his entire clan get wiped out, his family getting murdered, and the fact that it apparently takes strong willpower to wield a demonic sword.
Saw this pop up a few times in the updates and thought it would be different or interesting, but it looks like it already devolved into the same bland isekai story I read dozens of times.
Also, I get that it's in a chapter, but when drip fed in parts, I can imagine the pacing getting shot in the foot and forced to crawl.
