Fukami is quiet and calm most of the time, often only using few words to get his point across. He has feelings for Wadanohara, but was jealous that Samekichi stole her attention. However, he does not act on these feelings without outside interference, even going as far as to comfort Wadanohara in accordance with Samekichi's disappearance in the true end of Wadanohara and the Great Blue Sea.
