Doujima has messy black hair and wears glasses.
Doujima is a laid back and friendly guy who doesn't seem to take many things seriously. Although he is occasionally perceived as shallow, he does have a strong moral center as he gets upset when he finds out that Akari Hyuuga's crush was lying to her and it is also implied that he may not be too book smart.
At middle school, Doujima attended kendo club with the previous student council president who recommended him to the student council.
