HERO (also known as Henry) is a young, 19 year old med student with a mild personality. He is passionate in domestic work like baking, cooking, and cleaning, making him an ideal employee. HERO has a charismatic side that he uses to charm others. He notably possesses talent in succeeding in virtually everything he tries, though he admits his reputation is heavily exaggerated. HERO is rather calm and understanding towards anyone he meets, even trying to comfort them in times of distress. Despite this, he is rather mellowed down in terms of personality, mostly due to suffering from depression over MARI'S death and trying to get his life back on track. HERO also appears to keep his emotions in check most of the time, although he does get deeply emotional whenever he remembers MARI's presence. Regardless, HERO still ties to remain strong for his friends and will do anything to make sure they feel comfortable and safe.
