Natsume Yūjin-chō

Natsume Yujin-cho also known as Natsume's Book of Friends in english. It is a Japanese manga series by Yuki Midorikawa. The story is about Natsume, an orphaned teenage boy who has the ability to see spirit. He getting this power from his grandmather, Reiko. Natsume had get a book that containing the name of spirit after her grandmother died. The book would let the Natsume contact the spirit and order them. However, Natsume try to release and give back the spirit their name. Beside, Madara, also call by Nyanko-sensei also become Natsume bodyguard. 
Some people say that this story is mainly to see interaction of Natsume and Nyako-sensei, but I more love to see the story of spirit. All the stories are about love, but the sadness is come with love between different races when they accompanied (human and spirit), this feeling is quite lovely, but also fragile. I feel that the book and the name are just an introduction, the main things from the story is about how the human and the spirit live together, the life is ordinary but bring out the feeling of sadness and happiness together.
Although the story is consisting many positive value such as helpful, love, thankful, and so on , but it is also shown some negative things behind the story. Human also afraid and try to removal something they are do not know and can’t control.  Reiko was no friends and always be bulling just because she can see the spirit. Other than that, human try to wipe out all the sprit without think the spirit is good or bad just because they are afraid something unknown(spirit).
What is human? There are good people, bad people, people who is inclusive Natsume, people who is cannot understand Natsume. Spirit also have good and bad. But most of them are very simple. However the spirit can live very long but is it sad when they do not know what they wanted because of the long life. It is also full of sadness when Natsume and Nyanko-sensei build up the deep relationship because the Natsume will died in future while Nyanko-sensei can life very long.
