The group around Furin infiltrates the hideout of the mysterious group KEEL, recognizable by their dragon bone logo, to rescue Nagato. KEEL operates with criminal methods, brutally ambushing opponents with superior numbers and deploying weapons. Despite warnings, Furin storms the location but is quickly overwhelmed by KEEL's members, who deliberately isolate the weaker ones.

While core fighters like Sakura and Sugishita demonstrate their strength, the group finds itself in distress as KEEL's tactic exploits their numerical advantage. The pressure mounts when Kaji and additional reinforcements arrive, turning the tide. Kaji emphasizes Furin's principle of protecting the city and its values – which includes rescuing Nagato.

In the escalation, the battles now focus on KEEL's leaders. Sugishita and Sakura push forward despite injuries, while Kaji takes over coordination.
