(Have brains) (Not novice) (Have system) (Multiple female protagonists) (Timeline confusion is set by the author)
My name is Shuji
Hmm... To be precise, his name is Senju Shuji now.
He traveled through time and is now a ninja
Of course my current goal is to survive World War II
As for what happens after that?
Let's have a few more children with Tsunade and the others first to restore the Senju clan.
When Shuji stands at the top of the ninja world, standing in the sky
"I just want to change this sick world!"
"Trust me, I really don't eat beef!"
Shuji said this.
