Uncle Abe is reaching out from the heavens, causing storms, stopping trains, and overfilling hotels, just to give this absolute dolt a chance to finally make a proper move. Don't waste it, the birth rates are at stake!
Honestly, I kinda prefer that there's no sex. Hell, should go even further and make the girls not initiate things as blatantly and shamelessly as they did this chapter. It was completely out of place.
I wouldn't overestimate the fan as a weapon. Even when made out of steel it cant weight too much (or it would seem very sus during any sort of weapons-check), and due to short length the energy transfer wouldn't be that efficient.
Still, better than nothing, and definitely very stylish.
Something I dont get is why is MC surprised at all... He's been living in this world for years now, and studying its laws and customs. Why does he still act like he reincarnated yesterday?
