I doubt, but can't say for sure, otherwise why Megumi or any previously user of Ten Shadow didn't use it to tame Mahoraga

no no that was back the .I stopped

well I didn't mention it because at that high level of fight it's doesn't amount to much, later on his magic alone is so strong that he don't need those things like thing like his allure he got from unicorn, I stopped mentioning it because he control that power with his magic learn how to use it and honestly never had to use it

well he exist in future so what you think

he train his body to use more of ofa but now he can only use rofa which is half of ofa and thus even his body got affected

this one in tentional

well there is no other shikigami that can handle urashiki beside mahoraga and one other

even after knowing what formulae you need to solve a math problem, its not given that you can solve it, it needs practice, that not his memories nor his body. Though he can learn thing faster due to having everything give to him and even having both memories and muscle memory with you, it will still require some part of training on his part

possible I haven't seen boruto after all

sure sure
