As you already said, Indra/Asura aren't ordinary people, but sons of the Sage of Six Paths. OK, Hagoromo and Hamura had something similar to this, but they weren't actually reborn in someone, plus they've appeared for some reasons - Hagoromo's reason was to monitor the destiny of the ninshu, and Hamura's was to save his brother's world from his offsprings, who misunderstood his will. Indra's/Asura's reason actually was the settling of their unfinished business, which is already done.
