Vietnam is described as "headstrong" due to the number of strong women in Vietnamese history. She appears a bit shy when it comes to her looks, appearing apprehensive when Taiwan wishes to take a picture with her and is uncomfortable wearing a Santa outfit in a 2009 Christmas Request. In a blog post, Himaruya mentioned that Vietnam has a natural skillfulness and uses it to create a variety of different objects, and Austria mentions in one comic that he special ordered cinnamon from Vietnam.[2] In the volume four strip Ilha Formosa ~Beautiful Island~, Vietnam claims that she is not photogenic.[3] In the Christmas 2011 event, Vietnam shows that she doesn't know how to smile.[4]
