Asahi Azumane

Asahi Azumane is a 3rd year student in Class 3 from Karasuno High; he is one of the boys' volleyball club's wing spikers and its ace. He has long hair which is usually styled as a bun behind his head and dark brown eyes matching his hair as well as his eyebrows. He also appears to be growing a short scruff on his chin, his overall appearance makes him look way beyond his age yet slightly unapproachable.

In Season 2, he is shown no longer wearing his hair in a bun, but swept backwards with a sports hairband. In contrast to his appearance, he is rather quiet and gentle, and has difficulties realizing that he is Karasuno's ace, as he initially doesn't feel that way. He shows to be weak-willed at the beginning when he leaves the team before the first years come, feeling that he let down his entire team when they lost against Date Tech High even though they counted on him.  After coming back to Karasuno, he realizes that his will to play volleyball is much stronger than he thought, and with the help of his teammates, he acknowledges his position as Karasuno's ace (even though he is still mocked sometimes by Daichi for not having any "ace-like presence") and gains self-confidence. 

Asahi is said to have a "Glass Heart", taking everything that is said about him to heart, and becoming depressed because of it at times. While he still feels insecure about a lot of things and seems to be quite a scaredy-cat, he clearly states that he has no intention of letting anyone take his ace position away from him in later chapters, showing his development from the beginning.  Asahi is the most powerful attacker in Karasuno. He is known for a strong spike that can blast past most defenders. His best spike is when he's given a high toss that is slightly away from the net. After their battle against Nekoma, Asahi learned how to do a back row attack. As a result of the Summer Training Camp Arc, Asahi learned to perform a jump serve. His receives also became more solid than during the Interhigh match against Seijoh.
