Reiji Kizaki (木崎 レイジ Kizaki Reiji?) is a character in the manga and anime series World Trigger. He is an A-rank agent, leader of Tamakoma Branch's Kizaki Unit, and Chika's mentor. He is skilled in the use of Sniper, Attacker, and Gunner/Shooter type triggers, so skilled that he is known as the "Perfect All-Rounder."
He has short auburn hair (which was originally black, as seen in the old group picture) and green eyes. He is tall and quite muscular. He usually wears a grey-purple shirt and black trousers. When in Trigger Mode, he gets a grey-blue shirt with the Tamakoma Branch symbol on the sides of the sleeves, a black flak jacket, black military pants, and combat boots.
Reiji is a very calm and serious individual. He can be very strict, as shown when he scolded Chika for forgetting the basics of being a sniper, though she proved him wrong by showing him she didn't. The only case in which he has been shown to lose his cool is when Yuri is around.
Chika Amatori: Chika Amatori is Reiji's student. Though he is strict at times, it is clear that he has confidence that she could become a great sniper one day. There is mutual respect between the two.
