The Infinite Tsukuyomi does not affect Hashirama, Tobirama, Hiruzen and Minato because they are reanimated. Hagoromo, the Sage of the Six Paths, appears and explains to the four that Hashirama and Madara are the reincarnations of his sons Ashura and Indra. Hagoromo recounts the tale of how he founded Ninshu, the Ninja Creed, and about the lives of Ashura and Indra.
Even if you are far apart,
you will always be together.
حتّى لو كنتم بعيدين، فستكونون سويًّا دائمًا
Selbst wenn wir getrennt seid,
seid ihr doch nicht allein.
Siempre estarán juntos aunque se separen.
Siempre estaréis juntos aunque os separéis.
Sebbene divisi, sarete sempre uniti.
Mesmo longe, vocês estarão sempre juntos.
