The rules explicitly state that arrest prevents voting for night kills. And if there are no votes, no one dies. As long as Onion did what he claimed, Kuro is in the clear. Unfortunately we can't know if Onion targeted Kuro, we just have to take him for his word.
Finish reading Ginyu's post.
"would block each other,
but the Nightkill is higher in the ability order list (yes, the Nightkill is not an ability, but it needed a place in this list)."
This doesn't make sense to me. If arrest can stop the nightkill, it has a higher priority, or it would come into effect AFTER the nightkill. However, this is the interpretation the host has, so it means Kuro could have been the mafia. No more likely than anyone else however. I think kuro is 95% likely to be town, but CONFIRMED is a status only afforded by 100% certainty.

Being very hasty considering the day has JUST started, and she can send her target to Calindu by PM. What if people follow suit with that vote, then afk and don't change vote when she's given her target?
