Hige seems to know how to function the best in human society, even wearing a dog collar, although the true meaning behind his collar is revealed later in the series that is a tag/transmitter . He tends to use his intuition more than the others, but only when he's not thinking with his stomach instead. Hige is quite the ladies' man and is always on the look-out for a nice girl. He has the best sense of smell between the others. Hige seems to be a Mexican wolf in the series.
Hige's name means "beard" or "whiskers" in Japanese.
