There was once a man named Wilbur,
Who played music, played games, had friends.
One day, he found a painting,
that brought him more bliss than they can.
There was once a man named Techno,
Who told stories, raised cities, and burned them down.
One day, he was offered a throne and a crown,
A god by his side, sparks fly, as he watched the fire burn his town.
There was once a man named Phil,
Who sought skies, sought freedom, sought life.
One day the forest gave him thus,
A hero he became, a human he was not.
There was once a man named Tommy,
Who wanted excitement, experience, adventures.
One day, he left his fairytale alone.
and his friends, he left behind forevermore.

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!"
