Shigekuni Genryusai Yamamoto confronts Yhwach for the first time in a thousand years. Stern Ritter members NaNaNa Najahkoop, Äs Nödt, and Bazz-B join the fray but are quickly defeated by Genryusai. Despite losing his subordinates before his eyes, Yhwach condemns them for their foolish actions, further convincing Genryusai that his old nemesis has not changed at all. As Yhwach finally draws his sword against Genryusai, the Soul Reapers notice an abnormal change taking place across the Seireitei.
