Yugi Moto. (Not: Atem/Spirit of the puzzle Yami) for a student in High school Yugi could pass as a Grade school student, however he never lets his size compromise defending his friends. in a show where fighting evil isn't a contact sport Yugi shows us that you can fight the shadows no mater what size you are. Kazuki Takahashi stated that Yugi is in fact, diabetic, which is how he explained his short stature. that's what Takahashi's thinking was when he made the character
