Saki infiltrates the mansion of Shigaraki-ro with Nishiwaki. There, his troop is waiting for them in ambush. Saki and Nishiwaki fight valiantly but the number of the soldiers is too much versus only two.
Nishiwaki, while in the midst of battle, starts telling Saki why he is fighting with her like this. He used to love her mother Michiko and her family, and he has been regretting that he could not save her family 12 years ago. He, at least, wants to save Shiori, the only survivor of the family. Shigaraki plots to kill both at once and sends a soldier, Ranmaru, with a time bomb installed in his body. However, Ranmaru also wants them to defeat Shigaraki-ro and he blows himself up at a distance from the two.
Saki and Nishiwaki are rushing toward Shigaraki-ro but Nishiwaki is beaten and Saki passes out.
The lunar eclipse, the time that the cup is filled with the elixir of immortality, is getting very close. Shigaraki-ro is exhultant in the victory. Then, the chimes of the music box are heard. Saki bursts out from the pond at the very moment that Shigaraki-ro is about to sip the elixir. She, with whatever the power she has left, breaks the cup and falls back in the pond. Kurayami-shirei arrives and his gun puts an end to it all.
