During the Goodwill Event, when Todo Aoi finds out Itadori Yuji's taste in women, he goes into an intense day-dream where he and Itadori are high-school classmates. In his day-dream, Todo declares his intention to confess to Takada-chan, who is also a student in the same school in his fantasy, and he has the following conversation with Itadori:
Todo: Why are you sure that I would be dumped?
Itadori: On the other hand, why do you think she would agree?
Todo: Anne Sullivan once said this to Helen Keller. "How can a fool think about losing before he does it?"
Itadori: That's what Inoki said.
I have heard of Anne Sullivan and Helen Keller, but who might be Inoki? My best guess is that it refers to the wrestler Antonio Inoki, but I am unable to confirm or deny it. In case it is an actual quote said by a real person named Inoki, could someone please provide a source for it?
Furthermore, as Todo comes out of his day-dream, he recites another quote (at least, the subtitles that I have seen place these words within double quotes):
At home, we are invincible…
Perhaps this is also a real quote, said by the same Inoki encountered earlier? Any help in tracking down these quotes would be great!
