Timeskip- 6 years

Like this 6 years passed by and now Kenshin is 13 years of age and a Jonin of Konoha. Many major events happened in these 6 years.

YEAR - 1

Just after their mission Kakashi resigned from Anbu Ops. This news shocked many people on Team Ro as Kakashi was one of the important pillars of their team. And in absense of him, the team's strength decreased.

After Kakashi, Itachi was made their new Captain as he have similar strength to Itachi (and his strength is still increasing unlike Kakashi whose progress have stagnated)

After a month of break Kenshin started doing his missions. In his break he was doing some D ranks mission like finding somebody's cat, cleaning some tunnels and etc.

Few months later, Kenshin and gang(All 4 members from his 1st mission) did a mission that was mentioned in the series that is 'to eliminate saboteurs from Kusagakure'.

And after few months later Itachi resigned from this team and went to another team as a captain.

Like this months passed by and by the end of the year Team Ro recieved two missions which ended in failure and those were 'Investigate Barrier Transgression' which might be Obito's doing to transfer some attention from Uchiha's and 'Stopping Uchiha Coup d'etat' as Itachi massacred his Clan.

When Team Ro responded Itachi has already killed everybody except Sasuke who has just suffered from Tsukuyomi. After that Team Ro got another mission to protect Sasuke till he heals.

Kenshin's father who was working on Police Force got promoted to higher ranks to fill up the void caused by the death of Uchiha members. Kenshin's father also trained a lot now a days as he didn't want to be too weaker than his son.

YEAR- 2

In this year not many thing happened except from killing potential targets that may cause disturbance to the peace between Nations. Kenshin also become a master assassin. It is due to his superb chakra control and chakra masking. And also due to his move 'Peaceful Dawn' which caused almost no sound.

The big event was Anbu Commander taking the role of their captain as this team was comprised of highly capable individuals even after the loss of 2 Jonins.

In one of the mission, they had to protect the target, a famous individual. And other team also joined in this mission. This mission was going very smooth until two S rank ninja Kakuzu and some other Kumo missing Ninja came in. Their team fought him but got decimated by them.

Kenshin knew Kakuzu's weakness from the series but still he only managed to destroy 2 of Kakuzu's heart. Anbu Commander who has strength above a jonin but lower than Kage fought for some time before dying.

As for the other team, they killed the S rank ninja but most of their members died including their Captain. There was some sort of relationship between the other captain and Anbu Commander. And Kakuzu used this moment to strike Anbu Commander who died.

Kakuzu was going to take Commanders heart but was fiercely attacked by Kenshin, Tenzo and rest of the members. And Kakuzu who was already very tired from fighting Anbu Commander and getting his two heart blown by Kenshin fled from there.

They have completed the mission but it came at a very big cost. Kenshin then took off the mask of Anbu Commander to check his real identity. When he took off the mask, he was shocked to see a man with similar looks to Asuma and Hiruzen.

Kenshin somewhat guessed the identity of the other woman but still decided to check the identity of the woman captain from other team. She has some similarities to Konohamaru as he has seen in Anime.

Kenshin knew that they were parents of Konohamaru. Kenshin sighed thinking about it. After that they went back to Konoha. When they went to Hokage to report, Kenshin saw how Hiruzen's eyes almost became vacant hearing the death of his son and daughter in law.

After that Hokage told them to leave him alone. After some days, Kenshin was promoted to Anbu Captain of Team Ro and him, Tenzo and Uzuki were promoted to Jonin level.

Kenshin's parents were very happy about their son's success. Kenshin didn't forget to spend time with his family. Like this, year came to an end without any major incident.

YEAR- 3

In this year some events happening which caused him to gain lot of credits. The mission was to infiltrate Kumogakure and Iwagakure and kill some targets.

This earned Kenshin a name in the Bingo book as well. Though they don't know his name or anything but they gave description of his height and approximate age and power level. The bounty on his head was-

By Iwagakure- 20,000,000 ryo

By Kumogakure- 15,000,000 ryo.

Kenshin was also awarded to go to the vault where they keep A and S ranks jutsu. This caused immense benefits to Kenshin. This was mostly the reason why he joined Anbu instead of joining the Academy.

Kenshin learned major A and S rank lightning, fire and wind release jutsu's. He also learned up Flying Thunder God jutsu of both Tobirama and Minato. He also picked up a lot of scrolls of Iryo Ninjutsu and Fuinjutsu.

By the end of that year, Kenshin learned all the jutsu's he has brought with him. Kenshin now became the most proficient ninja in Kenjutsu and Fuinjutsu in the Village.

Kenshin found fuinjutsu very intriguing so he started to play around with it which almost would have shocked the hell out of others as it is very dangerous. It used incorrectly one may even die. But Kenshin who was into knowledge ignored this.

Kenshin compared fuinjutsu to arrays of Xianxia novels as both use energy in the nature (nature chakra or qi) and run it in specific pattern according to the array or seal to produce results.

YEAR- 4

As Kenshin's objective was completed, he resigned from Anbu and became a normal Jonin Ninja. In this year Kenshin mastered all the Iryo Ninjutsu that he has taken. Kenshin's chakra reserve also reached Kage level but due to his high proficiency in masking chakra, nobody knew about this.

As Kenshin was 11 years old, he started to put weights to increase training. He spent this year on Iryo Ninjutsu and Taijutsu mainly.

Kenshin also made changes to "Breath of the Sun" technique as he channeled in specific chakra system to increase the power behind the strike.

Kenshin didn't know about other breathing technique but Breath of the Sun technique is very powerful as Kenshin with all his strength is still not able to use basic breathing technique for more than 6 hours.

Kenshin started to spar with Might Guy in Taijutsu and learned more about Taijutsu. He also learned Hachimon Tonko or 8 inner gated technique from him. He can only release 5 gates directly but couldn't open 5th gate which might be due to his physique weaker than Guy.

The training with Guy was very exciting for him as there is at least someone who is stronger than him in Taijutsu otherwise others who are stronger than him is mostly due to more chakra and ninjutsu.

Kenshin wanted to give Guy his breathing technique but didn't give it as it is his biggest secret. But Kenshin gave a modified version of breathing technique to Guy to increase his training training efficiency. Kenshin also has given a breathing technique it to his parents when he became a jonin.

Later he also gave it to Kakashi as well who also joined them in training....
