It is noted that one cannot really tell what is on his mind, due to his lack of inaonyesha emotion. He has also been described as being "in many ways, a sturdy big bro". In the 2010 krisimasi Event, it is hinted that he might have a vague interest in fashion, as he was somewhat disturbed kwa China's choice of casual wear and alisema that he should think about it zaidi often. He also seems to be afraid of the dark and admires Jackie Chan.
He speaks in a mixture of Japanese and English, with a Gyaru-o dialect, a speech pattern like that of a teenage boy which is often translated much like Poland's Valley Girl speech. Before appearing in the fake preview for Hetalia: Axis Powers Volume 3 where he "promised" China he would not draw explicit pictures anymore, he appeared in artwork for the series and was featured in the profaili page of the sekunde volume.
