Kiragi is the son of Takumi, the cousin of Shiro, one of the grandsons of Sumeragi and Ikona, and one of the step-grandsons of Mikoto. He was left in a Deeprealm much like the other children of Fates to safely protect him during the war.

Both optimistic and friendly, Kiragi thinks of everything in a positive way. Kiragi idolizes his father and aspires to be like him one day. Whenever Takumi downplays his compliments, stating that he is not worthy of such praise, Kiragi always tries to cheer him up and inspire confidence, even if he has to cry to make him say it. He hopes to one day be able to wield the Fujin Yumi like his father, but at the present, he cannot wield it during the events of Fates. He also loves his mother, but initially refuses to study as he considers it a waste of time. However, in his support with her, after seeing her efforts to make it appeal to his passions, he is inspired to follow through with his education, proving to be an adept scholar when he tries.

Kiragi is a skilled hunter and is his one true passion. Kiragi's skill as a hunter has developed numerous skills including the ability to hide his presence, track targets from a considerable distance to the naked eye, and hit targets from said distances with little effort. He also is a skilled pathfinder, able to travel through very dangerous terrain with little effort. This is evident in his supports with Rhajat and Midori. In Rhajat's case, he gets some mushrooms and is happy to give them to her, even though she mentions the skeletons at the bottom of the cliff, and later on, algae near the mushrooms. In Midori's case, he gets a special plant that she requested which is found in a dormant volcano filled with poisonous gases, much to her concern.

Despite being royalty, he dislikes being treated like one or being called a prince. His supports with the female Corrin show that he left his caretakers because they refused to let him go outside worrying that he might be hurt or killed. This is also evident in his supports with Forrest and Hisame. However, his supports with Female Kana show that he genuinely worries about his responsibilities as a prince, and that one of the reasons he is so fond of the forest is because it is a place where he can just get away from everything for a while. This is also noted if he marries, as his ending implies that he returns to the mountains to live a quiet life after helping his family.

He has the sharpest eyes in the army. His birthday is July 4.
