Natsume, don't cry.
Natsume, smile.
Natsume, monsters are not actually scary. What is scary is the human heart.
Natsume, please keep your kind heart and treat those monsters with an equal heart. You will find that they are actually friendlier than humans.
Natsume, you have to wait for me to come back.
Natsume, don't forget what I said.
In Natsume Shiki's memory, there is a girl, a girl with a warm smile, a girl who can see monsters like him. That girl said to him: Natsume, I like you the most.
