The story is about a boy named (M/n) Akane. He was bullied when by the Generation of Miracles except Kuroko. But on the last day of middle school, (M/n) left vowing he would beat them no matter what and moves to America and starts becoming better and better at basketball soon mastering all the skills nicknaming him 'Dragon Blade', light on his feet, eyes and accuracy are as sharp as a blade and the strength of a dragon and the skills the wielder possess. He has a tattoo on his back that ends at his stomach because of the nickname 'Dragon' by his old teammates in America called 'The Knights'. He has dark blue highlights in his hair and a lip, eyebrow and ear piercings which an 8 pack. His eyes are Blue but turn Crimson Red when he is in the zone while playing. He doesn't open up much in the beginning but once you know him the more he opens up. His states are through the roof in every skill that he can play in any position and can also have the ability to be like Kuroko but prefers to use his skills with another skill in order for no one to copy his moves and unable to see him until the minute he makes the shot. He is from the team in America known as 'The Knights' that are number one in America after earning their place in nationals. After his parents died in a horrible car accident, he inherited his parents companies in both America and Tokyo, Japan.
