This volume of 「アマチュアビジランテ」 centers on the sudden return of a terrorist who disappeared twenty years earlier, now back to set off what is called a final war. He is described as a seasoned ideological criminal, someone who has survived countless confrontations and knows exactly how to manipulate chaos to his advantage. His reappearance throws the series' ongoing struggle into a new, far more dangerous phase.

At the heart of this entry is a clash between the protagonist and an opponent who proves far tougher than anticipated. The story places this confrontation in a very public space, a subway station in broad daylight, turning an ordinary commute into the stage for an all-out struggle. The contrast between the mundane setting and the scale of violence gives the conflict an unsettling, almost cinematic charge.

Readers drawn to the series for its sustained intensity will find that intensity pushed further here. The fight is framed as the culmination of long-building tension, a final reckoning rather than just another skirmish, and the story leans into that sense of finality. The protagonist is shown facing circumstances described as his greatest crisis yet, suggesting that this confrontation tests him in ways prior conflicts did not.

What makes this entry worth attention is less a twist in premise than an intensification of everything the series has built toward: a returning foe with history and skill, a public battlefield that raises the cost of failure, and a hero pushed past his limits. For anyone already following the story, this is the moment the series has been steering toward, delivered with the same focus on tension and consequence that has defined it so far.
