Blue Lock Chapter 327 kicks off the Side-B selection process with typical brutality, serving as a reminder that Ego Jinpachi isn't the only mastermind happy to sacrifice geniuses on the altar of glory. The JFA President has summoned every rejected player, every international prospect, and every talent still asleep in the hope of bringing them to a savage tournament.
Blue Lock Chapter 327 resurrects Ryosuke Kira seven years after his awful elimination, lands Seishiro Nagi in Selection Room One like a landmine, and introduces Dutch division two striker Shindo Haneru. Kira is looking to have Isagi's head on a plate. Nagi looks bored. Haneru tosses a polite smile while others stand around sweating. They've returned to the tag game format, but this time, 299 will get eliminated in the first round.
Buratsuta Unleashes His Master Plan

Blue Lock Chapter 327 starts with Buratsuta speaking to a big crowd of 301 young strikers. The JFA President tells them he wants to beat Blue Lock and create the world's number 1 striker. This secondary program continues with the same approach as Ego Jinpachi's philosophies, but it's independent from the Blue Lock center.
Buratsuta promises the two remaining survivors outrageous extravagance. They'd represent Japan in the U20 World Cup knockout stages, directly versus the finalists of Blue Lock, and he'll provide his full support for commercial endeavors and transfer to an international league.
Kira's Vengeful Return Shakes the Foundation

Ryousuke Kira is back, and it's been seven years since his horrible knockout in the opening chapter of Blue Lock. Blue Lock Chapter 327 shows us that the former "Japan's Hope" is still bitter about losing to Yoichi Isagi in such a tragic way.
Kira goes so far as to criticize the selection process itself for being manipulative, brainwashing, like Ego Kenpachi. Kira details that he will only destroy Isagi to prove the philosophy of Blue Lock incorrect. Kira's determination seems to imply there is unfinished business beyond pure rivalry.
Mysterious Dutch League Player Enters the Scene
In Blue Lock chapter 327, we see a brand new character, Shindo Haneru, a striker with super international experience. He's polite but confident and plays forward in the second Dutch division. He actually got an invite from Buratsuta himself!
Haneru straight up recognizes Kira (nicknamed "Japan's Hope") right off the bat. Haneru and Kira realize that they were grouped in the same selection room, so it was going to be inevitable that they would face off against each other. Haneru's calm demeanor feels like a stark contrast to Kira's volatile anger and explosiveness.
Nagi Makes His Long-Awaited Comeback in Blue Lock Chapter 327

The last panel of the chapter is just straight-up shock value. Blue Lock Chapter 327 shows Seishiro Nagi, by himself, in Selection Room One, and wearing a white Blue Lock jumpsuit. He says "Sup?" which is his first appearance after four months of being gone from the manga.
Nagi being in the selection room changes everything. He can play at a level that is much higher than any of the eliminated players around him and is clearly the frontrunner to take one of the two available spots.
Familiar Faces Fill the Roster
Blue Lock Chapter 327 recalls a lot of characters from prior arcs. It's been noticed that players who have been eliminated in earlier arcs, like Okawa, Nishioka, and the Wanima twins, are in background crowd shots. There's also Ali's "Messi," and both Himizu and Hiagi come back.
The chosen structure, the tag selection structure, appears to follow a similar architecture to the original Blue Lock tag games. There are going to be 25 rooms with 12 players at a time, so the tag game format seems to give the same elimination structure as before, however, with lethal stakes.
Room One Becomes Ground Zero
In Blue Lock Chapter 327, we learn that all three - Kira, Haneru, and Nagi - are sharing the selection room. This generates an explosive combination with an eliminated genius facing a current genius while an unknown player watches from outside the room.
Kira's seven-year grudge, Haneru's unknown characteristics, and Nagi's disproportionate components guarantee an intense rivalry. Chapter 327 clearly establishes Kira, Nagi, and Haneru as important potential protagonists in the Side-B story.
Blue Lock Chapter 327 successfully launches an ambitious new arc. The Side-B selection introduces fresh dynamics while honoring the manga's competitive foundation. Kira's return provides emotional weight, Nagi's involvement guarantees quality action, and Haneru adds unpredictable elements to established rivalries. Part Two promises even more revelations as the selection truly begins.
