Cater Diamond

Cater Diamond is a third-year student in Heartslabyul. He's very perceptive with great communication skills, as well as popular, stylish, and a gourmet. However, he can sometimes be cruel. Cater has orange hair, the top portion tied back into a ponytail while the rest hangs straight. His eyes are green. Under his right eye, he has red makeup shaped like a diamond. He wears a white shirt, with a red diamond patterned vest covering it. Over the vest he wears a blazer that the others in his dorm wear, except for Riddle. He wears a black and yellow ribbon around his waist, and red and white high tops. He also wears white trousers. Cater is an easy-going and peppy third-year. He is an avid social media user and keeps up with all the latest trends. He is noted to use lots of modern slang in his speech. "I am him, and he is another. Split Card!" Cater's unique magic is called "Split Card" (舞い散る手札スプリット・カード, Supuritto Kādo; lit. "Scattered playing cards"). He is able to split himself into clones that each act independently. Creating and keeping the clones up is exhausting for him, so the magic does not last long. He has a great sense of balance, according to Riddle. Because of his dad’s work as a banker, Cater's family had to move about once every two years, all over the world. Cater hadn’t had any long-lasting friends because of this. Because of his family's frequent moving, he feels like a pro at packing things.

Cater has two older sisters who, according to him, boss him around. He has described his sisters as “unreasonable,” his dislikes in his profile are listed as “having to suck up to his sisters,” and when everyone was going home for winter holiday, he said he’d rather stay with Trey’s family. In his voice lines, he mentioned that he can’t relate to Yuu feeling homesick because his sisters would just be waiting for him at home. His sisters rated everything by how cute it was, and if something “wasn’t cute” to them, then Cater would have to redo it.

His sisters would get more excited about his birthday than he would and buy him all kinds of presents he didn’t particularly like (such as stuffed animals, dolls, perfumes, soaps, etc). But they weren’t trying to be intentionally mean, and recently they have started paying attention to what he really wants.

When he was about 10 years old, his mom and his sisters were always baking sweets. Cater was excited about this at first because it meant he could get lots of treats, but his sisters would make him eat everything. If he refused, they’d look so disheartened, and Cater couldn’t say no to that, so he kept forcing himself to eat. Because of this, he now hates sweets.

Cater is sociable, expressive, fashionable, trend-conscious, adaptable, and highly attentive to how people and experiences are presented. His speech is cheerful and casual, and he readily approaches people across dorm and year boundaries. He likes lively interactions, jokes easily, and tends to keep conversations moving rather than allowing situations to become overly serious.

He is exceptionally socially perceptive. Cater pays attention not merely to what people say, but to emotional boundaries and the atmosphere around them. His explanation for why he would want Vil as an older brother is revealing: beyond Vil's fashion knowledge and fame, Cater admires what he perceives as Vil's ability to read people's emotions, understand the room, and maintain appropriate distance even with family members.

This emphasis on proper distance appears connected to Cater's own experiences. He is friendly with many people but dislikes feeling imposed upon, and his stories about his sisters repeatedly involve accommodating other people's wishes while suppressing his own inconvenience. His ideal relationship seems to combine warmth with respect for personal boundaries rather than demanding constant intimacy.

Cater is also highly sensitive to trends and collective attention. Magicam is not merely something he occasionally uses; he actively studies what photographs perform well, which locations are trending, how to obtain unusual angles, and what subjects attract engagement. When discussing a famous waterfall, he has already analyzed why its photos are popular, what limitations other visitors face, and how broom flight could let him create images nobody else can reproduce.

Consequently, Cater often evaluates experiences partly through their presentational potential. Food can be interesting because it is visually original, a café because it is photogenic, a dorm because its aesthetic suits photographs, and a destination because it is currently attracting attention online. He even loses interest in visiting a trending location if he expects the trend will have disappeared before he arrives.

Yet his online orientation is more deliberate than superficial compulsiveness. Cater thinks carefully about photography equipment, lighting, backgrounds, composition, privacy, cosmetics, posting schedules, and audience response. He wants more photogenic walls in his room because repeatedly setting up equipment is inconvenient, but rejects filming extensively around the dorm because doing so could violate other students' privacy.

He also has a strong aesthetic and stylistic sense. Receiving the diamond suit in Heartslabyul immediately prompted him to consider how its color would coordinate with his existing cosmetics. He enjoys experimenting with makeup, combining styles, following new products, and adapting his appearance to different outfits and situations.

Cater's upbeat presentation can conceal preferences he does not readily advertise. His dislike of sweets is something he kept secret despite constantly attending Heartslabyul tea parties, and Trey apparently understood it before Cater formally told him. This suggests that Cater's public persona is not necessarily false, but it is selective: he prefers presenting whatever version of himself keeps the situation enjoyable and socially smooth rather than exposing every private discomfort.

He is from the Shaftlands. He is skilled at astrology. He is a part of the light music club with Lilia and Kalim. He likes trying out cafes. He can skateboard. His favorite food is spicy ramen.
