Yuri Briar and Yor Forger from Spy x Family are siblings who, after their parent's death, raised each other, leading to Yuri's intense, almost protectiveness over Yor, viewing her as his sole family and source of happiness, often clashing with his brother-in-law Loid Forger due to jealousy and his perceived role as her protector, though he's just a young, emotionally immature adult deeply bonded to his older sister.
