Hyugo Sugimoto

Hyugo Sugimoto is a foreign exchange student at Olympieus University and one of the institution's highest-achieving students, despite being rarely seen in class. Friendly, intelligent, and endlessly curious, he has a warm, approachable nature that stands out among his peers. He enjoys collecting random facts, detective films, video games, and sweet desserts—especially anything with berries—and has a strong dislike of spicy food, nagging, and injustice. Physically, Hyugo has a youthful appearance with soft, baby-faced features. He stands at approximately 174 cm (5'8½") tall and has shaggy teal hair with long side bangs, a thick strand falling over the center of his forehead, and a distinctive rat-tail at the back. His bright sky-blue eyes and easy smile make him appear cheerful and approachable. He is most often seen wearing a black long-sleeved shirt beneath a white short-sleeved button-up, layered with a green sweater vest, black slacks, and occasionally gloves. Although Hyugo is naturally sociable and energetic, there is a mysterious side to him. He disappears for long periods without warning, earning the nickname "Mister MIA" from other students. His frequent absences are never fully explained, yet the university allows him unusual freedoms and continues to recognize his academic achievements despite his lack of attendance. Rumors circulate that he carries out responsibilities outside of ordinary student life, though the nature of these duties remains unknown. Likewise, very little is known about his childhood, family, or life before arriving at Olympieus University. Hyugo has a habit of sneaking onto the university rooftop, a place students are normally forbidden from entering. Despite repeated attempts to stop him, he always seems to find his way back, and eventually the staff more or less accept that keeping him away is impossible. This strange privilege, combined with his unexplained disappearances and exceptional academic record, has made him something of an enigma among the student body. Among all the students, Hyugo is Sol's closest—and effectively only—true friend. Their personalities are complete opposites: Hyugo is outgoing, expressive, optimistic, and talkative, while Sol is quiet, emotionally reserved, observant, and withdrawn. Even so, Hyugo never seems discouraged by Sol's silence. He happily fills conversations with stories, trivia, and questions, often drawing Sol into situations or conversations he would otherwise avoid. Sol rarely speaks much in return, but he quietly tolerates—and, in his own way, appreciates—Hyugo's company more than almost anyone else's. Their friendship is built on quiet trust rather than dramatic displays of affection. Hyugo is one of the few people capable of bringing Sol out of his shell, while Sol provides a calm, reliable presence that balances Hyugo's boundless energy. Despite the many mysteries surrounding Hyugo's life, his loyalty, kindness, and unwavering optimism make him an important constant in Sol's otherwise isolated world.

Hyugo Sugimoto and Solivan Brugmansia are an unlikely pair. Hyugo's bright, talkative nature contrasts sharply with Sol's quiet, withdrawn demeanor, yet the two share an effortless friendship built on trust and understanding. Hyugo never expects Sol to speak more than he wants to, happily filling the silence himself, while Sol accepts Hyugo's boundless energy without complaint. Between them exists an unspoken agreement: Hyugo never pries into Sol's past or the walls he keeps around himself, and Sol never questions Hyugo's frequent disappearances or the secrets he chooses not to share. Neither asks for explanations, because neither believes they're owed them. Their friendship isn't built on knowing everything about each other—it's built on accepting what remains unsaid.
