Before mesting Ayato trained his powers a lot mainly his Chakra control and creating new spell.He was able to awaken his Sharigan in a months time,while being able to create his
favourite power, which was Power of Destruction
When used it creates great explosive power and can completely annihilate things when used. The Power of Destruction is said to be a very difficult power to defend against due to its erasure properties, as the most effective way to guard against it would be to counter the destruction blast with ranged attacks.
But that's when his mother found about his powers,which led to having to play dumb and reveal some of his abilities.
Thus leading to his mother fearing for his life and going to the Saegusa family for help.Which was good course of action,since Nakajou family were only rich,they were not one of the Ten clans or even the the 100,so finding somone to help them was a start or protect them.
So the Nakajou family moved into Saegusa main household, it was silent process.
But in the process of exploring with his younger sister, Ayato was lost and Azusa possesses a more childish face, yet whenever she directs a teary-eyed face upwards, she unintentionally gives off the impression of a child about to cry. She's also been described as a squirrel.
So being Azusa worried"Are we lost, Onii-chan?
Ayato shook his head and replied"No, we are going the right direction."
That's when they heard a voice"Who are you?"
Azusa quickly hid behind Ayato, who covered for her and he saw it was little Mayumi Saegusa,she could be called a young elven Princess
But snapping out of it he answered, not wanting any misunderstandings"We moved in here, my name is Nakajou Ayato."while gesturing towards his sister and added"This is my sister Nakajou Azusa."
Azusa gave shy nod, while Mayumi was good at seeing peoples intentions, since she was the third oldest child of Saegusa heir Kouichi.This made her to come in contact with a lot of people, who had different intentions.
But here she saw these two really didn't have any bad intentions and they were just lost.Also she heard her father say something about visitors arriving and them being important.
Mayumi nodded and with genuine smile said"I am Saegusa Mayumi and welcome to my home."
Ayato and Azusa bowed, while this was the start of beautiful friendship for Azusa and between Mayumi and Ayato something more.
As time went Ayato started to train under Kazama Harunobu, who was B-ranked Magician and also a member of the magical community that has the Ten Master Clans at the pinnacle.
Ayato relationship with Kazama wasn't great at the start, because his chilly relationship with the Ten Master Clans, who are the epitome of modern magic, although his relationships with those in his troop do not count.
But with time Ayato was able to get close to him.
