Sekai's pretty smart to reveal his secret using the magic stone in his hands. Now he has Fury and Lucille to help guide him through the village, and now he has new information to help him investigate the murder of Aksho Law.
Fury figured out what may have happened pretty quickly. Good for her, that means she's willing to cooperate with this perverted hero, but now she knows something terrible happens when the village opens up.
I feel bad for the Aunt, she has reasons to be suspicious. But she has no reason to believe anything Sekai is saying, so of course she'd be ok with having him killed.
I wonder what the hag is doing perched up on a tree? She seems to be smirking, did she cause this?
