Growing up, my mother has been super overprotective of me.
Having lost my father because of muggers, mother has gone paranoid and kept me inside the house, cutting of any form of communication outside, other than the internet.
She didn't even let me out to go to school, and had me homeschooled.
And when I use social media, she wouldn't let me use my face as the profile pic, and if I make friends, she would block all the female friends I make, confusing me.
I asked mom about that, and she said that she wouldn't let me, her adorable son, be friends with female strangers, because they might trick me.
I, having been cooped up for years in the house, have decided to sneak out.
But that wasn't the luckiest of my days.
Being finally outside, I was filled with adrenaline, and I did not notice the car speeding towards me.
Kanda Kyoichi transmigrated to Konoha and became a temporary instructor at the Ninja Academy. Fortunately, he awakened the Mentor System.
By teaching others, he could earn rewards.
Thus began Kyoichi's career as a "teacher" in the ninja world.
Shisui: "Sensei's unique interpretation of the Will of Fire has given the Uchiha Clan a true sense of direction!"
Asuma: "The essence of the jade lies in protecting the people, with the advanced leading the way for the less experienced. Only then can Konoha become stronger!"
Kakashi: "He's my life mentor. He transformed Konoha!"
...
Years later, in the memoirs of Kyoichi, now the Hokage, he wrote:
"I honestly just wanted to be a life mentor!"
