Seishiro Nagi Manga Blue Lock Chapter 306
The final page detonates like a landmine: Seishiro Nagi is in Selection Room One.
Casually leaning against the wall in a white jumpsuit, Nagi says only one thing: “Sup?”
After four months of absence from the manga, his return instantly changes the balance of power. Nagi is far above the eliminated strikers surrounding him — and he’s the undisputed favorite for one of the two Side-B survivor spots.
Chapter 327 also shows familiar names in crowd shots — Okawa, Nishioka, the Wanima twins, Ali’s “Messi,” Himizu, and Hiagi — proving Side-B is not just filler, but a major revival of past talent.
The tag-game format returns, but this time the number is brutal:
25 rooms
12 players per room
299 players eliminated in Round 1
Side-B is survival of the smartest — and the cruelest.
The most dangerous room holds the three biggest wild cards:
| Player | Motivation |
|---|---|
| Kira | Seven-year grudge against Isagi |
| Haneru | Unknown talent with international polish |
| Nagi | Genius with no equal in the room |
Blue Lock Chapter 327 sets the stage for a rivalry that could redefine the series’ power structure.
The emotional stakes (Kira), the technical ceiling (Nagi), and the unpredictable variable (Haneru) guarantee that Side-B will not be a side story — it’s a war.
