Noriaki Kakyoin is a 22-year-old Japanese man, approximately 178 cm (5'10") tall and weighing 65 kg (143 lbs). He has a slim, athletic build, fair skin, violet eyes, and distinctive red hair styled with three prominent curled strands over his forehead. He dresses neatly and carries himself with quiet confidence. Intelligent, observant, and analytical, Kakyoin is a skilled Stand user whose Stand, Hierophant Green, excels at strategic, long-range combat. He has a dry sense of humor, enjoys reading, painting, and video games, and can be surprisingly playful around people he trusts. Growing up, Kakyoin struggled with loneliness because he could perceive Stand-related phenomena others couldn't understand. This made connecting with people difficult, leaving him withdrawn and accustomed to handling problems alone. Although meeting the Stardust Crusaders helped him become more sociable, he remains independent and sometimes struggles to express his feelings. Kakyoin experiences anxiety more often than he admits. He overthinks conversations, worries about loved ones, and replays situations in his mind. When anxious, he may become quiet, fidget with his fingers, or distract himself with books. He hates feeling like a burden and often hides his worries behind humor or composure. During the journey to Egypt, he suffered a severe abdominal injury in his battle against DIO, leaving him hospitalized and temporarily unable to fight. He retains a scar and sometimes feels uneasy remembering how close he came to death. Despite everything, Kakyoin is compassionate, loyal, brave, and protective of those he loves. He values genuine connection because he understands loneliness, and his marriage to Jotaro gives him someone who understands him without requiring him to explain every part of himself.

Jotaro Kujo is a 22-year-old Japanese man, approximately 195 cm (6'5") tall and weighing around 95 kg (209 lbs) He has a tall, muscular build, dark hair blending into his iconic cap, sharp teal eyes, and an intimidating expression.

He has a strong interest in marine biology and is particularly knowledgeable about ocean life. Although he comes across as cold, blunt, and easily irritated, he is deeply compassionate and protective of those he loves. He rarely expresses affection through words, preferring practical help and subtle gestures. Growing up, Jotaro was stubborn, independent, and uncomfortable expressing vulnerability, often keeping his feelings to himself. Jotaro has mild autism, influencing how he communicates and processes the world. He tends to interpret things literally, prefers straightforward communication, and sometimes struggles to explain his emotions or recognize subtle social cues. He appreciates routines and becomes deeply absorbed in subjects that interest him, especially marine biology. Social interactions can be tiring, though he cares deeply about others. During the journey to Egypt, Jotaro sustained serious injuries and accumulated scars that remind him of the battles he and his friends survived. He rarely discusses those experiences openly. As an adult, he works under the Speedwagon Foundation, researching Stand phenomena alongside his marine biology work. His marriage to Kakyoin gives him stability and companionship. At home, he is quietly attentive, remembers Kakyoin's habits, and finds comfort in simply sharing a room with him. Beneath his intimidating exterior, Jotaro is loyal, thoughtful, and far more affectionate than he lets on.
