Ryusei Ishida

Ryusei is a tall, tanned young man with spiky blond hair, with two strands falling down either side of his face. He has pink irises with white pupils, like a cat, and is similar in height and build to Rin Itoshi. He is very expressive, and is often seen with a grin that resembles a snarl.

Ryusei Shido is another eccentric player in Blue Lock who has a strong penchant for violence, more specifically, physical altercations. At the core of Shido's personality is the drive to play soccer, not because he enjoys the sport, but because it is a biological phenomenon that makes him feel complete. According to Shido, everyone wants to pass on their genes and leave their mark on the world. Scoring goals is Shido's way of doing this, and it is his only goal. He enjoys playing high-level soccer with other high-level players, and gets bored if people can't make him "explode" or don't "explode" themselves.

He can be considered the polar opposite of Rin Itoshi, being completely self-sufficient and instinctive in his soccer. A notable trait of Shido is his penchant for violence to get what he wants, often unwilling to work with most people (if anyone at all). He seems to be fully aware and accepting of the toxicity of his behavior, and only feels mild remorse after being electrocuted and jailed for being overly aggressive and threatening to cause serious bodily harm to other players.

He seems to overcome these feelings when he is freed from his behavioral captivity by Sae Itoshi, who asks him to join him in playing high-level soccer and allows him to behave however he wants, as long as it is for Sae's sake. After being released from Blue Lock under Sae's supervision, he seems to become even more openly violent and often gets into arguments with the members of the Japan U-20 team, especially their best player Shuto Sendo, who initially has no respect for Sae.

Shido can be outright friendly and even affectionate towards others, such as Sae Itoshi, who gave him the opportunity to play with him and developed his level of play in the process by showing him a type of soccer he had never experienced before. Although he is prone to violence, Shido is capable and willing to acknowledge the skill of others, praising Isagi for "playing better" in the first game of the Third Selection (when Rin did not), despite Isagi stealing a goal from him.
