He has dark hair and a buzz-cut with bald stripes along the sides of his head and big, oval-shaped eyebrows.
Kiryū appears to have a tendency to over-analyze. He is shown stressing over the ulterior motive behind Bokuto eagerly greeting him prior to their match, even though Bokuto had no such motive. Despite being a top 3 spiker, Kiryū admits to not having confidence in his own abilities. In the past, he struggled with feelings of not being able to be the dependable ace his team needed, like Ushijima was for his school. That part of his personality remained unchanged even in high school when playing against Bokuto brought out Kiryū's insecurities. However, he possesses a strong sense of responsibility to his teammates that drives him to improve and overcome heavy pressure.
He currently attends Mujinazaka High, located in Ōita Prefecture, and is one of the nation's top three aces. Back in middle school, Kiryū was already a reliable ace who led his team to a second round victory in the National Middle School Athletics Tournament. Due to their similar play style, he was compared to Ushijima and said to be a better all-rounder. However, Ushijima broke through the heavy defense constantly marking him whereas Kiryū succumbed to the pressure and backed away from the challenge. After their loss, Kiryū was devastated to hear his setter apologizing to him and promised he will hit every toss.

Kiryu appears on the second day of nationals with the rest of his team after being seeded into the second round. He is seen observing the first set in the match between Inarizaki and Karasuno. His team won their first two matches and lost to Fukurodani in the quarterfinals.
According to Kuroo, he is one of the top 3 spikers of Japan. He has a powerful spike rivaling Ushijima's, but he also has formidable leg strength due to the emphasis his school puts on physical training. Even when hitting sub-par tosses, Kiryū is able to maximize the strength of his spikes without losing precision. He also has a very powerful jump serve and very proficient at receiving.

- "There are people out there who never care about how others are rated, nor do they ever compare themselves to others... if anything, it's like they don't have a single errant thought, to the point where it seems as though they don't know anything else in this world but volleyball, and it's like they only exist to play volleyball... it's people like Ushijima, or Bokuto... how could I stand losing to them?" (Chapter 330)
- "I know, that to be without fear, or anxiety, to be able to move one's body the way one wants it to move...to be able to enjoy oneself, is what it truly means to be the strongest." (Chapter 334)
