The Blue Lock manga is currently more exciting than ever, with the U-20 World Cup match between Japan and Nigeria underway. Meanwhile, equally thrilling developments are unfolding in the background, as Hirotoshi Buratsuta launches a new project called Side-B to select three of his own players to represent the national team in the World Cup.
Notably, the recent chapter saw Nagi finally embrace the idea of becoming a villain by joining the JFU Chairman’s selection program. Due to this, most fans may believe that the Lazy Genius will become Buratsuta’s greatest tool against Project Blue Lock. However, apart from him, one more fitting contender can take on the role.
Ryosuke Kira’s ideals and goals perfectly align with those of Buratsuta, due to which he will likely end up being the chairman's ultimate weapon to bring down Jinpachi Ego and seize control of his project.

Why Ryosuke Kira’s return spells danger for Project Blue Lock
As most fans remember, Ryosuke Kira was originally Japan’s National Treasure and a player believed to be capable of leading the country to greatness. He shared a rivalry with Isagi and seemed to be polite and kind on the surface. However, after his shocking elimination in the first stage of Blue Lock after a combined maneuver from Bachira and Isagi, Kira’s true personality was unveiled.
This displayed a narcissistic and selfish individual who believed he was superior to others and was unable to accept his elimination. Even as he exited the facility, he was filled with rage and defiance. Due to this, fans were eagerly anticipating his return for a long time.
Finally, Blue Lock chapter 311 put countless theories to rest and revealed that Kira would participate in Buratsuta’s program to select two players to represent Team Japan, with the third spot confirmed to belong to Sae Itoshi.
When compared to Sae and Nagi, Kira’s role in the narrative may not be as significant. However, he is possibly the most threatening individual to Blue Lock’s existence because his goals are similar to those of Buratsuta. Ryosuke Kira is a player who never agreed with Jinpachi Ego’s teachings, arguing against his mentor as soon as he entered the project.
After his elimination, he has most likely become more twisted, desperate for vengeance against those who ruined his career. Hirotoshi Buratsuta’s sole motive for creating the “Buratsuta 3” is to find a person who can infiltrate Blue Lock and oppose Jinpachi Ego, proving his football method wrong and ultimately driving him into retirement.
Though Nagi and Sae have agreed to be part of Buratsuta’s squad, they will not be blindly obedient to him. Kira, on the other hand, would have no reason to oppose the chairman, as he also wants to defeat the central figures of Blue Lock - Ego and Isagi.
His skills will be shown in the Side-B program, where fans can expect him to have undergone frightening improvement fueled by his anger. Therefore, in the highly probable scenario that he joins Nagi and Sae in the “Buratsuta 3,” he will be the player that everyone will need to watch out for - passionate, hungry, and on the quest for revenge.
