Chapter 159

The sumo exchange peaks when Shin succeeds in flooring Haruma, and he silently prays the blow will keep the big man grounded. Instead Haruma pushes himself upright and steps toward him, curious about the freeze technique Shin used earlier, though Shin gives nothing away. Redirecting, Haruma asks why his opponent has steered their brawl clear of the weapons on display. Shin explains he never intended to kill him; he and his allies are only trying to derail X's scheme.

Reluctant to burn more time, Haruma calls the confrontation off and floats the idea of a future rematch, assuming they both live. He walks away, then buckles beside a statue as the weight of Shin's final hit lands, and he worries about letting down his partner Kumanomi. Attention swings to Amane, who is locked in combat with the Carolina Reaper. Shishiba shows up to back him, the two trade a few words, and Kumanomi arrives to join the fray.

Spotting the damage Shishiba already dealt her, Carolina needles Kumanomi over the injuries, drawing her irritation. Refusing to be slowed, Kumanomi snatches up an axe and prepares to advance. Watching it unfold, Shishiba cautions Amane not to become a mirror of Carolina and Kumanomi someday, foreshadowing a possible collision among the four of them.

Shin knocks Haruma to the ground and reveals that his true aim is stopping X rather than killing his opponent. Haruma withdraws with a promise of a rematch, then collapses near a statue as the severity of Shin's last strike sinks in. The narrative shifts to Amane's fight with the Carolina Reaper, where Shishiba lends aid and the freshly wounded Kumanomi arms herself with an axe. Shishiba warns Amane against following the bitter path of the two assassins, hinting at a wider clash to come.
