Green was a member of an assassination group - Elite Seven, he was a serious and intelligent young man who had a weird fetish when it comes to Armpits. He was usually calm and relied on strategy rather than brute force. He used a whip-type weapon called Sidewinder, which Green can use to attack multiple enemies at once. He has a massive crush on Akame and always tried to impress her. He was especially attracted to Akame's armpits and even got a nosebleed while looking at them during a mission.
