So you prove my point but my logic is flawed? explain. Amaterasu was given a name in the manga. But was never seen used in battle til Itachi vs Sasuke
I have this game. I know that the last 3 are Amaterasu variants that were made up for the game. I called everyone who called it Tsukuyomi an idiot. Because Its obviously not Tsukuyomi U_U
Your logic was flawed because you said "back then Amaterasu wasn't mentioned int he anime or manga" well that doesn't really matter at all since it was called Amaterasu in the game released just before this one now does it? On top of that the information you gave as a fact was wrong. Amaterasu was mentioned in Chapter 148 and episode 85, episode 85 was released in Japan on May 26,2004(seeing as manga gets there first that would mean the manga revealed it before then) yet the game was released in Japan on September 30, 2004. (FYI they both predate the American release as well- Ep. 85=4/28/07 game= 6/12/07)
The point is you may have been right but you came about it like an ******* despite having incomplete information. Seeing as the series(game and manga) already used Amaterasu as a move name, it's not unreasonable that people were thrown off by the weird names of jutsu that never actually existed in the manga.
