Main World.
Konoha Year Twenty-Two, autumn.
British Continent, New Capital.
Imperial Palace, Underworld.
The gray-white sky never changed. There was no sun, moon, or stars, only a hazy glow. The ground was a boundless, half-solidified "carpet," seemingly composed of countless tiny particles of light. A strange air mingling peace and deathly stillness pervaded the space.
Toyotomi Yinglang stood at the head of the Naihe Bridge, gazing at the faintly glowing river flowing slowly beneath it. The River of Forgetfulness. Its waters could wash away memories, allowing the souls of the dead to forget their pasts and be reincarnated. Tsunade stood beside him, holding a cup of hot tea, a trace of impatience on her face.

Tsunade frowned slightly.
