He noticed something is off about Karen, and manage to fool her saying that 'when you look at goblins, you might think they're cute or such but not with sexual desire right? the same applies for goblin, we don't desire human'
As Karen was moving away, another goblin found her and thought 'oh, were you taking a bath? let me go get a new set of cloth for you' which adds to her misunderstanding that goblins indeed do not sexually desire human.
While the goblin is away, she ponders aloud, at which point some spooky dude is like "well, let me take care of that then"
The goblin then came to Akira, and ask him to come and show him the cloth that was covering Karen earlier on the ground
Akira felt some strong sense of 'death' and immediately tell the other goblin to run back to the village NOW.
He then use light to reveal the assassin, who's holding onto Karen.
The assassin toss Karen down, Akira move in to catch her.
At which point the assassin stab him.
But surprise it's a shadow clone and Akira knock the assassin out.
As he's about to pick up the dagger the assassin dropped, he felt that strong sense of [Death] again.
And Karen say "That's the Goblin Slayer...." and the chapter ends there.
So hopefully next chapter will see the resolution to this little arc with Karen.
