Chapter 142, titled X's Goal, reveals the bomb hidden in Mafuyu's own body and pits Shin against the captured recruit. Their clash exposes Uzuki's demand that Mafuyu kill an Order member, just as the JAA chairman arrives.
Searching for the others, Shin comes across Kaji unconscious on the floor and hurries over in alarm to ask what went wrong. Kaji manages to warn that Mafuyu is present and that a bomb has been set in Mafuyu's bedroom. Kashima then breaks in to correct him, explaining the device is actually embedded in Mafuyu's foot.
Because the foot is too small for the sensor to register, Kashima notes, the blast would reach only about four meters, and the bomb is rigged to trigger the instant its host dies. Shin tells him not to worry, reasoning it will only go off if Mafuyu deliberately takes his own life, and Kashima assures him the situation is contained.
Shin tracks Mafuyu down and confronts him head on, warning him to surrender or be taken by force. The two come to blows, and Mafuyu opens strong with heavy strikes, though Shin holds firm. Amid the exchange, Mafuyu lets slip details about Uzuki, revealing that the only path into the Order is to defeat one of its members. As the fight continues, the JAA chairman finally enters the building.
Shin finds Kaji knocked out and learns Mafuyu is present with a bomb. Kashima reveals the bomb is implanted in Mafuyu's foot with a four meter blast radius, set to detonate if the host dies. Shin confronts Mafuyu and the two fight, with Mafuyu landing powerful early blows. Mafuyu discloses that joining the Order requires defeating one of its members. The JAA chairman enters the building.
The chapter opens with a color page and clarifies the exact placement and mechanics of the bomb tied to Mafuyu. It appears in Volume 16. Sakamoto, Amane, Uda, and Natsuki Seba are mentioned, and Sei Asaki's arrival sets up the confrontation ahead.
Chapter 142 reveals that the bomb Uzuki planted is embedded in Mafuyu's foot, small enough to avoid detection, with a blast radius of about four meters that triggers the instant its host dies.
Kashima is the character who corrects Kaji's warning about the bomb in Chapter 142, clarifying that it is implanted in Mafuyu's foot rather than his bedroom and explaining its trigger mechanism.
During his fight with Shin, Mafuyu lets slip that the only way to join the Order is to defeat one of its members, exposing part of Uzuki's scheme.
Shin confronts Mafuyu and warns him to surrender or be taken by force, and the two come to blows, with Mafuyu opening strong with heavy strikes that Shin manages to withstand.
As Shin and Mafuyu's fight continues, the JAA chairman finally enters the building.
