In Himouto Umaru-chan, Umaru Doma has two distinct "states":
I am wondering how do both English-speaking fans and Japanese-speaking fans call these two "states". Is there an official name given?
From what I observe, when she changes from the "small" state to the "big" state, the text "うまうーん" appears behind her:
So I suspect that the big form is called うまるーん.
