Aoi Asahina, sometimes shortened as Hina, is a pleasant, nice, optimistic and fit extrovert. Athletic, Aoi makes sure to keep her body in shape. However, if one were to assume she has no place in her diet for sweets, they might be surprised to find she loves doughnuts! And luckily for her, for others maybe not, she has developed the ability to swallow and keep large quantities of food in her stomach and digest them with ease... And if she wishes, she can do the same with people with no problem.
