Jikan;
Nichiren identified himself with the bodhisattva Joygyo - Superior Conduct and that's it. Anything else is a sectarian invention. I've posted the quotes from authentic gosho (Nichiren's letters) and J.Stone the Nichiren scholar restates Nichiren's viewing himself as Jogyo in her work "Original Englightenement and the Transformation of Medieval Japanese Buddhism" p. 259
Nichiren taught; Although I myself may be insignificant, I propagate the Lotus Sutra and therefore am the envoy of Shakyamuni Buddha.(P333 On Various Actions, Shujyu Onfurumai Gosho, Selected Writings of Nichiren by CUP) more specifically in the other authentic gosho:
"Nichiren Shonin, if it is according to the Sutra, is the Saint who is the Messenger of the Tathagata [Buddha]Who Attained in the Long Past, the Descent (suijaku) of the Bodhisattva Jogyo, the Practicer of the Doctrine of the Original of the Hokkekyo, and the Great Teacher of the Fifth Five Hundred Years [sicne the Extinction of the Manifest Buddha]
