Use your main account man.
1) Doesn't train. Resources to cheating.Isn't stronger than Shinki and then defeats a god.
2) Chakra control superior to a god.
3) Physical resistance superior to a god, he endured a chakra ball clash.
4) Fainting after using Karma and then using Karma at will.
5) Vanishing Rasengan. Even he doesn't know how he does it.
6) Defies the laws of the chakra sword versus AO.
7) Uses Karma and saves everyone.
8) The very existence of his eye is an asspull alone and sets the ground for more future asspulls.
9) Karma now enhances his strength AND his jutsus, like.. for real?

I could go on.
Boruto is the epitome of unexplainable asspulls.
I am actually happy he did. Things were kind of boring around here.
I dont think you actually know what an "asspull" is...
1) This isn't an asspull, these are character flaws at best which any good character needs to have (also Boruto does train since the chuunin exams so I am not sure why you brought that up). Also he landed the final blow on Momo with Naruto's chakra after Momo was already completely exhausted and out of chakra, this is not an asspull, its how Naruto works. Hell, even just using all your chakra in itself can kill a person.
2) Again, same as before. Momoshiki was already defeated, Naruto gave Boruto the chakra he needed to land a final blow for symbolism. Not an asspull.
3) Again, he was amped with a shit ton of Naruto's chakra and he was facing an already defeated opponent. (Your first three points are pretty redundant)
4) You are assuming Boruto activated his Karma by will against Kashin Koji, even though we know that Bourto's karma activates with Kawaki's and Kawaki would have been in combat at around the same time as Boruto meaning Kawaki most likely had his karma activated, thus activating Boruto's.
5) Vanishing Rasengan may be an asspull, but it is established that Boruto is a genius and that ninjutsu comes easily to him so in-universe it makes sense.
6) Boruto didnt defy the chakra sword, he just used it effectively for a short period of time.
7) Not an asspull? Boruto has Karma, this has been established previously, how is it an asspull of him to use it? Its not.
8) His eye has been foreshadowed since The Last and makes perfect sense as Boruto is essentially the combination of Hagoromo and Hamura, giving him access to Otsutsuki blood line limit, his mother is the Byakugan princess who was given Hamuras chakra and his father is the reincarnate of Ashura who recieved Hagoromos chakra.
9) Again, not an asspull. Obviously Karma amps Boruto's stats, just like every power up in any shounen ever.
By your logic, literally everything in the Naruto verse is an asspull including Kurama, Oro Curse Mark, 8 gates, sage mode, etc. Stop hating and just enjoy the story (or dont, just dont complain).
