Just think of it as AU.

source? I want to see when in canon at 6 years old he was able to use a jutsu that required jonin's lvl of chakra. I didn't write anywhere that it's a forbidden jutsu, only that it requires a big amount of chakra to use. Just because he is an Uchiha, doesn't mean that he has a big chakra reserves (especially at 6years old) otherwise we could make a comparison to minato, a civilian (that had bigger reserves than most non clan kids) to a sakura and lee, which would be a nonsense. I'm waiting for your source other than 'trust me bro, i've read many fanfics'.

Mc:

I thought that we were reading ninja academy students sparing, not jonin/kage fights.

(facepalm) Didn't know that hyuga academy students knew such techniques. What are you trying to prove here? Are you reading about academy ninja's students that are sparing or about chunnin/jonin fight? Hyuga here didn't use such thing, that's why this whole situation is so stupid when you will take into account the monologue of other characters.

You peseants just can't see mount tai.
