The content is great and interesting. The art is very beautiful. The character's feelings change through the story, it's very realistic. Although it make readers sad sometimes, there are some funny situations. I can say that this manga is very promising and exciting. SPOILER: the story about the boy named Fushi (Immo), throughout the story, it is the development of the boy, from mosnter to becoming a human. On his adventure, he met a lot of friends, there are people who love him and there are people who hate him and using him as a tool. He learned how to speak fluently and how to become a proper human. He learned what is love and what is hate. When the time came, he fought with all he got and saved people. He realized he don't want to see people dying in front of him, though he is an immortal, he used to not know what death is. This is why this manga is very unique and outstanding.
