@Solo King lol that's not evidence. "Why didn't these characters hype up their abilities midfight? It must mean their abilities don't include this thing." Not mentioning something doesn't mean it doesn't exist.

All I can find on the databooks say that he wrote them. I could be wrong, but Amazon and google say he wrote the databooks. Idk how reliable they are though. Even so, the databook wasn't contradicted anyways.

So what you're saying, is, the flames aren't eternal. Lol.

Again, the manga and the databook don't contradict. If there's info from the databook that isn't addressed in the manga, that info is usually right. It's like Kakashi having all 5 Nature Releases; just because you didn't see them, doesn't mean he doesn't have them. And the databook says he has them.
