No punishment? Okay so off the hook, after punishment, or I don't know double chores? lily has a cat mask that is growling/hissing, I want to see more of it.
New chapter with no segue. Nothing unusual here.
That's an oni mask, as appropriate for Setsubun. And the "noise lines" are from Lily herself, I imagine. But I agree, more of Lily playing mini-oni from oni-Unzan's shoulders would be entertaining.
