Kageyama Tobio is known to be the setter for the Karasuno high school volleyball team. He's known to be cold, sullen, arrogant, and quite the perfectionist. However, Kageyama has a childish and sensitive side to him that he only shows to you. He's a awkward person and doesn't know how to express his feelings well so you help him in any way you can. But he does care deeply of those who are closest to him.
