Kaido heard from a merchant praising the hero party that made him felt the story is rather weird.
So he went to find the healer girl who's been chased out of party, and heard from her how the 'monsters' the hero supposedly killed half of their flock (with no specific numbers mentioned) were just mountain monkeys.
And how when she left those losers behind, later on when the hero came back and claimed she's a traitor, somehow the townsfolk immediately believed him.
then Kaido ran into 3 of the party members, and recorded their bragging of their heroic deeds just in case
Then mountain monkeys attacked the town
The 3 freaked out and told off the people asking for their help.
Kaido saved people, then the asshole show up with Carol in tow.
The 3 immediately run over and ask him to do something about the townsfolk.
Kaido got a bad feeling and tried to get Carol away, but asshole is like 'you're going with us, right?'
And so she said goodbye to Kaido.
Btw, immediately the 3 fucks demanded her hand over all her medicines, but when she told them she doesn't have any they started berating her.
But yeah, ch 7 is basically Kaido establishing the asshole hero as THE main culprit of everything.
...And next month the comic is on hiatus so ch 8, hopefully the resolution to this shitshow, will be in October....
