The only path to overcoming Hosen lies in restoring sunlight to Yoshiwara Shangri-La, the city perpetually shrouded in darkness. Seita races toward the control room, determined to shatter the iron seal that binds the city. Simultaneously, Gintoki and the Hyakka, led by Tsukuyo, fight a desperate rearguard action against Hosen’s assault. Yet, despite their valiant resistance, they are powerless to halt the King of the Night's relentless advance.
