After his mother's death, nobody was wishing to tell him

Gerald is the child of Patricia Walker and Edward Walker. He also was downcast and felt guilty after this event. When his grandfather scold him for everything that happened regarding Takumi, he didn't say anything, thus making Gerald realize and admitting his mistake. According to Edward, he is intelligent and has a sense of responsibility and tends to take everything upon himself, just like his mother. However, Gerald appears to also have a softer side. However, Gerald states his abilities are because he has important people around him, thus making him modest. Gerald usually tends to change from a strangely cheerful attitude to a dangerous one. Gerald cares for his family and its reputation and also for all the people around him. As claimed by Edward, Gerald really has the ability to manage business. He has some morals and is pretty respectful, as seen when he didn't check into Takumi's phone when he had the chance to do it.

Gerald is also quite calm, rational and collected. Gerald is seen to be sincere and serious when the moment calls for it. Though he appears devious and calculating, he is strangely jovial and enjoys teasing Cedric Morris, similar to how Takumi makes fun of his acquaintances. Gerald dislikes Japan for its dislike of smokers, though he does like the cheap cigarettes. He has a playful personality and, according to himself, he tends to overestimate himself when everything goes well for him.

Gerald has a same cool aura as his younger half-brother, but tends to change to a dangerous one when talking business and important stuff. After observing his reaction to the apples Misaki brought for Usui, Misaki Ayuzawa concludes (albeit comically) that Gerald and Usui are similar, yet not similar at the same time.

Even though Gerald and Takumi don't have the same father, they really do look very similar the only noticeable difference being their hair & eye color. Gerald is usually seen wearing a business suit. He inherited Patricia's weak body and it is assumed he has the same illness as her. Gerald is a tall, handsome young man with straight, dark blue hair and light blue eyes.
