what's the thing that was implied to be used against alice?
Miss had already slapped alice, so probably her hand? LOL
But if you are talking about what appears in the 3rd panel it is probably that yukkuri discipline device ( a stick with foam to cushion the blows enough so as to not break yukkuri skin.
How long are you going to keep this up?Eventhough I've been punishing you suitably each time... Whatever happened to my good girl Alice?Why can't you just listen no matter how many times I tell you or remind you?
