-15th October year 50 of konoha
"My current name is Senju Tetsuya, 5 years old, a reincarnator. As for my old name, it is now irrelevant since I already died.
It is no currently 5 days after the Kyubi rampage.
I'm currently in the hospital after being in a coma for 5 days. This body should've probably died during the Kyubi rampage considering my injuries but I took over so I miraculously survived.
My parents who were both chunins apparently died during the rampage, so now I'm currently orphaned and homeless since my house was destroyed back then."
"Well then, how do I survive in this world now?"
"I am now pondering whether to become a Ninja or to become a civilian making money with my previous life knowledge."
"I probably have to become a ninja since I need to become stronger in order to survive in this world. And I am probably not smart enough to become a big-time businessman anyway. Damn, is this God's way of telling me that Law school was a mistake since I get sent into a mostly lawless world."
"There is still 12 years before the start of the main story and 16 years before the Pain invasion and 4th Great ninja war so I probably have enough time to become stronger. At least, enough time to not become a cannon fodder."
"After I get discharged of the hospital. I should start training since there is an entrance exam in the academy.
I can already sense my own chakra due to my parents being ninjas so I currently have an advantage compared to the other people my age, excluding clan people. I am a Senju so I should have higher chakra and stamina compared to my peers"
"According to the memories of this body, in order to integrate into Konoha, The Senju clan is currently, scattered around konoha and Intermarried with other civilians so most of them lost their name. Only the clan chief and his family are still in the original clan land."
"The reason why we don't see much of the senju clan in the manga is probably because most of them died during the kyubi rampage since they were all the first to arrive during the rampage and the most of the ones that are still alive are either civilians or the ones that changed their names after intermarrying."
"I'll probably get moved to the clan land after I get discharged since the orphanages are currently overflowing with civilians now so I have to make a plan on how to act from now on."

-21st october year 50
"I finally got discharged yesterday and moved into the Clan land with other kids."
"I found out that the academy starts in march so I have 4 months to train for the entrance exam. before then, I have to rely on the clan for feeding and housing since apparently orphans receive free housing and a stipend if they succesfully enter the academy."
as Tetsuya was thinking, a tall man arrived
"Hello everyone, My name is Senju Basara, The kyubi rampage was probably the worst thing that befell Konoha and our Senju clan since the founding of the village.
Most of you are probably still sad after losing your parents. But your parents and relatives died as heroes protecting our village.
You should be proud of them since they upheld the will of fire and protected the future of the village which are kids such as yourselves..."
As the man continued talking, Tetsuya thought to himself:
"Damn, those kids aren't even in the academy and they're already brainwashing them with all that WIll of Fire bullshit."
...
Senju Basara:" Most of you will probably enter the ninja academy, so the clan is willing to sponsor the top students to contribute to the revival of the clan.
As for those who fail to enter the academy, The clan will provide them with food and housing until they reach the age of 12."
"Great! If I get ranked high in the academy, the clan will sponsor me with training ressources and jutsu. So I don't have to be a random cannon fodder with just the Three body techniques when I graduate. I should probably start Training starting as soon as possible."
...
"The first step of my training should probably be the Saitama training, it's probably not much for a true ninja but as a starting point, it's alright.
I'm still five right now so I should work hard to complete this workout before I get into the academy."
As Tetsuya was pondering his next move, a kid approached him:
"Hey, My name is Isao. We're the same age so let's be friends."
"Hi, I'm Tetsuya. Nice to meet. Sure let's be friends."
Isao:" So you're going to enter the academy too, right?"
Tetsuya:"Yeah, I'm going to train so I can get a good ranking and get sponsored by the clan."
Isao:" Oh, let's train together then."
Tetsuya:" Alright, but can you keep up with me? I plan to train like a madman."
Isao: "It's alright, I definitely can keep up with you. Since I plan to become the next Hokage.
I'll definitely become the strongest so I should train as much as I can" said the boy while pointing at himself and smiling widely.
Tetsuya smiled and thought to himself:" I'll probably have to train a lot so having someone else with me will probably help motivate me and I can also get someone to compare myself to"
