Seishiro Nagi/Relationships (2024)

Team V[]

Reo Mikage[]

Nagi has a very close relationship with Reo. He was Nagi’s first friend and they promised to win the World Cup together after their first meeting. Reo often gave Nagi rides on his back to carry him around, in an effort to make sure Nagi had to work as little as possible.

While initially reluctant to enter Blue Lock, Nagi agreed after Reo promised to take him to a more interesting life. He made Reo promise to stay together with him to the end, showcasing their close bond. In the tag elimination and match against Team X, Nagi even takes initiative to protect Reo from oncoming attacks by other players. He emphasizes their promise to stay together and the fact that they are partners. When Barou mocks him for being Reo’s slave, Nagi becomes annoyed and takes initiative to disprove that point. Naturally, Nagi's soccer at the start of Blue Lock revolved greatly around Reo. Reo's main role was to set up Nagi's ball traps by giving him long range passes or setting up his attacks.

After losing to Team Z, Nagi began investing himself more in soccer with a strong desire to get better and improve. Because of this, he began distancing a bit from Reo. Where Reo wanted to remain by Nagi's side, Nagi wanted to keep moving forward in soccer in order to pursue their dream. Thus, he actively pursued new opportunities to improve, such as when he decided to join Isagi and Bachira's team in the Second Selection, temporarily leaving Reo. As Nagi did not communicate that this was for the sake of their dream, it led to miscommunication and Reo thinking he was abandoned. Where Nagi was earlier very obedient with Reo, he later began developing a harsher stance with him after Reo pushes him away, telling him how their goal to become the best in the world wasn't such an easy thing to do and how Reo was forgetting their promise and not pushing forwards. In Nagi’s mind, this has all been for their sake, so he becomes frustrated that Reo is severing their partnership. He let him know that he wasn't going to just stay at the same level with Reo, but was going to improve and evolve, suggesting that Reo take these words to heart. At the end of their 3v3 match in the second Selection, Nagi even goes so far as to call Reo "a pain" when the latter showed his dissatisfaction with the changes that Nagi had underwent. Nagi felt that the soccer Reo plays is not enough for the kind of soccer he wants to play. He still, however, holds Reo in high regard and respects the decisions he has made (especially so after their match together in the Third Selection), and still considers him to be his friend.

In the U20 match, their relationship had somewhat restored, as Reo takes the initiative to give Nagi a towel during halftime. This is further supported when Reo is subbed in and they do some passing combinations, carrying a similar chemistry to when they were on Team V together.

During the NEL arc, Nagi joins the same team as Reo, Manshine City. While Reo was determined to become fully independent from Nagi, Nagi sought Reo’s help after struggling to score during the match. While Reo rebuffs him, Nagi pleaded and appealed to their shared dream of becoming the world’s best. Despite their fight, Reo agreed and they began combining even more in sync than ever before, as a result of their growth. Nagi scores with Reo’s help and they high five, bond rekindled. After the match, they appear to be as close as before, with Reo taking care of Nagi. This time, Nagi verbally expressed his gratitude towards Reo for introducing him to football. It is clear that their relationship and promise mean a great deal to Nagi.

Team Z[]

Yoichi Isagi[]

Nagi initially meets Isagi during the First Selection in the cafeteria when Wataru Kuon tries betraying Team Z to avoid getting expelled from Blue Lock. They have more of an interaction during the last game of the First Selection and they both witness each other's skills and presence on the field. Isagi sees Nagi's insane ball control and trapping ability while Nagi begins to recognize not only Isagi's spatial awareness ability but his potential and overall influence on the field. Losing to Isagi made him realize his dream with Reo could disappear, so he took the initiative to change. He sees Isagi as a rival who stole the light of evolution from him during that match, and has worked to reclaim it since. Isagi can sometimes be the voice of reason when Nagi and the other Team White members were bickering, but they are not close outside the pitch. Nagi is stated to not be close to anyone outside of Reo and Zantetsu.

As teammates on the field, they have a good chemistry and understanding of each other. Isagi takes full advantage of Nagi's trapping skills and ball control and Nagi takes advantage of Isagi's ability to create chance opportunities sometimes pushing him to get the goal he wants. They climb Second Selection and acquire Barou after their initial loss to Rin's Team Red. They lose a second time to Rin's Team Red in the Second Selection due to Rin’s "luck”. When Isagi was chosen by Rin to continue on, Nagi and the Team White promised to climb up and meet Isagi along with everybody else and Nagi watched as Isagi went on ahead to face the World's Best. This was yet another moment of Isagi stealing the spotlight from him, adding to his frustration as a rival.

They met again when Third Selection began as Nagi had kept his promised and was apart of the Second Team that cleared Second Selection. Though they did not play anymore official games together in Blue Lock they both made the Blue Lock 11 as offensive midfielders, directing supporting and attacking with Itoshi Rin. They have both steeled themselves for the Japan National Rep match

Off the field, Nagi goes back to his mostly indifferent personality and does his own thing ignoring what Isagi and everyone else says in favor of watching something or playing a video game on his phone. Though he does listen to what Isagi has to say when he is trying to speak logic on or off the field.

Hyoma Chigiri[]

Nagi and Chigiri only have a few panels with each other but Chigiri introduced Nagi to Noel Noa, the current best striker in the world, as well as other professional players. They appear to get along well, watching videos on Nagi's phone and talking about Chigiri's injury. They run "Nagi Seishirou's trap-whatever-you-can championship" to the dismay of Barou.

They work together well on the pitch, and were part of the second team to clear the second selection. They also both choose to go to England in the second stage of Blue Lock, continuing their time as teammates.

Team X[]

Shoei Baro[]

Nagi and Baro are rivals, though both share a goal to defeat Isagi in a game. Their first meeting is in the Team V vs. Team X match. After Baro calls a him a slave, Nagi retorts with how he is not a slave, but Reo’s partner, and begins becoming fired up. Nagi scores a goal which Baro calls boring, so the former initiates a play, something he rarely does, and deliberately targets Baro. After this goal, Team V wins 5-2 and Baro states in their next encounter, he will win.

The two next meet in the second selection in the 2v2 match. In the matching room, Baro walks in and Nagi makes fun of him, saying how surprised it is that the king was here. He challenges Baro, but due to the 24 match cooldown they are forced to wait. Once the cooldown is over, Team White (Yoichi Isagi and Seishiro Nagi) faces off against Team Red (Shoei Baro and Asahi Naruhaya). The arguments and insults once again occur between Nagi and Baro, but their scoring ability remains about even. When Team White wins 5-4, Isagi and Nagi decide to steal Baro.

As a trio now, it is made clear that Nagi and Baro simply do not get along in the slightest, especially as teammates. They break out into an argument practically as soon as given the chance. It’s revealed that Baro likes tidiness and cleanliness, much to the annoyance of Nagi. The two fight about this multiple times, in the room, baths, etc.

In the next match versus Kunigami, Chigiri, and Reo, Isagi and Nagi end up playing mostly as a pair which annoys Baro to no end. Once the trio wins the match, they all have different opinions as to who to take but surprisingly unanimously agree to take Chigiri.

After losing to Rin’s team in the 4v4 match, Isagi is stolen leaving Nagi, Baro, and Chigiri, the three of them deciding they would seek revenge. Back in the room, Baro and Nagi once again argue but eventually the trio agree they must evolve to reach their goal of beating Isagi. In their next 3v3 match, they win by Baro and Chigiri overcoming their weaknesses. When Nagi says he had overcame his and became mentally stronger, Baro laughs saying he had only been defiant, saying he would not change that easily. Nagi retorts that Baro was also defiant, but are interrupted with the decision to decide who to steal. The three of them agree to steal Zantetsu.

The 4v4 match with the team is yet to be seen, but the outcome is revealed that they are able to win. After this, the next time the two meet is in the Manshine City versus Ubers match. After losing, Nagi asks Baro about what his goal is- what his drive to play soccer is. Baro says it’s obvious that he wants to become the best in the world. When Nagi asks what comes after that, Baro answers he will create a new era and become the definite king. Nagi’s weak attitude annoys him, and Baro states that he isn’t even being annoying. After Nagi is confused, Baro says that his hunger is gone, and to go die at rock bottom if he does not want to properly change and find his ego.
