Aslan is a wise, gracious lion. He loves his family and the vast land of Narnia. He had only one wish. To have a child to love. And, he was one night blessed by moonlight magic, and given a human child. He named her, Ayla.
Ayla loves her people and her father. But, she often feels like an outsider. And, seeing as her father is a lion, she sometimes feels embarrassed by him. And, one night, she runs away. She finds herself in the human world. She's afraid and regrets her actions but, doesn't know how to get back home.
Years later, she meets the Pevensee siblings. While playing hide and seek, she and Lucy Pevensee accidentally find themselves in the magical land of Narnia. It was the start of a new, emotional, adventure for the five.
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!"
