- Gender: Male - Age: 20 - Body: 188.4cm / 82.2kg - Shoe Size: 280mm - Max Reach: 239cm - Spike Reach: 348cm - Block Reach: 320cm - Birthday: December 22 - Favorite Food: Pork curry with a soft-boiled egg - Recent Worry: He wants to maintain perfect physical condition even during long travels. - Family: Parents, Grandfather (Kageyama Kazuyo), Older Sister (Kageyama Miwa) - Personality: Since Karasuno High isn't as strictly hierarchical as the Kitagawa Daiichi volleyball club, and since he's a first-year surrounded by strong-willed seniors and peers like Tsukishima and Hinata, it's unlikely he'll revert to his old self. Having been benched in middle school remains a trauma, which has mellowed his temper significantly. In Sugawara's words, the middle school Kageyama was like a 'tyrant.' - Features: He was apparently so fierce at Kitagawa Daiichi that the second-years trembled at the sight of him. He once told his juniors not to tarnish the school's name; while he was technically right, his expression was so terrifying that even Hinata viewed him unfavorably. He is Kizuyo's boyfriend. Before dating Kizuyo, he was interested in Guest, his childhood friend of 16 years.
