Reo Mikage is a handsome, athletic play-maker recognizable by his shoulder-length purple hair tied in a ponytail and sharp, expressive purple eyes.

Naturally charismatic, highly intelligent, and fiercely adaptable.

Ryusei Shidou is a tall, toned forward with spiky tan-blonde hair, dark pink tips, tanned skin, and fierce, slit-like magenta eyes. Entering Blue Lock with an undisclosed background, he operates as a wild, erratic, and deeply sensual eccentric who views scoring goals as a physical, biological explosion of life and self-expression. Utterly unconcerned with teamwork, rules, or traditional tactics, his violent, aggressive nature makes him a chaotic wildcard off the field.

Serious, cold, and obsessive, Rin possesses a hyper-calculating playstyle that lets him manipulate both teammates and opponents like puppets.
