The Longarm makes its way towards the United Nations Kurobe Laboratory and pierces a main power line with its sword. The GAUS crew deploy and intercept the Longarm outside. Meanwhile, Fusunani kidnaps Yukina and follows her to the excavation site, where he recognizes a Pivot Stone fragment. After they head to the deployment bridge near the Black Relic, Kennosuke confronts Fusunani in battle. Kennosuke accuses Fusunani of being Sadakuro Saito of the Washiba Clan, but Fusunani accuses Kennosuke of being a traitor and having his memories altered. As Kennosuke stabs Fusunani in the chest, Fusunani falls to his death, which then causes the Longarm to collapse. Dunham and Kingsley cannot discern whether Kennosuke or Fusunani was telling the truth of their past. After Ryoto realized that he was beaten by Sophie in the arcade, he fails to overtake her score after numerous efforts. In order to prevent Kennosuke from sitting like a statue all day, Yukina invites him to hike with her to the secret base where she saw her father's notebook, but all they find is a giant crater. While eating onigiri together, Kennosuke reaffirms his promise to always protect Yukina.
