Kyoutani also comments on how he thought Yahaba was a 'more shallow guy' in which Yahaba agrees, and according to Kindaichi, he also seems to be a show-off (as seen when he throws a ball in front of Yachi so that she can notice him) (Source: Haikyuu!!

Team: Aobajousai High School Age: 17 Height: 179.3 cm Weight: 70.2 kg Birthday: June 10 Year: 3rd Year, class 5 Number: 4 Position: Wing Spiker Ability Parameters (out of 5): Power = 5; jump = 4; stamina = 4; intellect = 3; technique = 3; speed = 4 Hajime Iwaizumi is a 3rd year student from Aobaj�sai High; he is the team ace and wing spiker. He is also Tooru Oikawa's childhood best friend and "pillar". Iwaizumi is a stubborn but reliable teammate, often filling in Oikawa's spot as a morale booster if needed. He acts supportively to all, including Tobio Kageyama, and calls Oikawa out for his childish antics. He often resorts to violence with Oikawa, but this does not change the fact that he cares immensely for him, as shown when he makes an effort to stop Oikawa from either working too hard or losing confidence. Iwaizumi's firm-yet-caring attitude has lead to some members of the Aoba Jousai team to look up and respect him, even more than their captain. (Source: Haikyuu!! Wikia)
Team: Aoba Josai High, Kitagawa Daiichi (former) Age: 15 Height: 189.2 cm Weight: 74.3 kg Birthday: June 6 Year: 1st year Position: Middle Blocker Middle blocker of the Aoba Josai High School volleyball club. He was Kageyama's teammate back in junior high school. Kindaichi was one of the players who hated Kageyama's selfish plays and refused to understand him. Kindaichi appears to be quite competitive and a bit stubborn. It took him a while before he finally accepted that Kageyama has changed and even when he did, he still didn't accept Kageyama's apology, choosing instead to stay as enemies. He seems to respect and admire the third years of his current team, specifically Oikawa. After being complimented by the setter once, he stumbled over his "thank you" while standing stiffly with both arms by his side. (Source: Haikyuu!! Wikia)
