A young girl named Hijiro traveled to her new home with her parents. Along the way, all three had to enter the tunnel to reach their destination. But when he entered the tunnel, it seemed like he had entered a new kingdom. With hunger and tempting food Chihiro's parents were quick to eat. But the little girl herself did not like it and wanted to leave this kingdom quickly. Because he had been aware of something wrong When the sun goes down, a spirit will appear. and Hijiro's parents are transformed into pigs. Hijiro receives help from a boy named Haku and renames Hijiro to Zen.
During the day, Zen has to work in a bathhouse, but things keep getting chaotic, but Zen is able to overcome various obstacles with Haku's wit and help. The relationship of both the spirits and the spirits began to continue growing. and in the cartoon there are still ghost characters who are not so good but in the end, they have always been by the side. This cartoon has a rich and boring content, and there is always a story to try. and there are also various thoughts inserted Whether greed makes people find bad things and pure love of Zen and Haku. and also insert a way of thinking that if you don't work hard, you won't have a stand This cartoon gave me peace of mind and sadness along the way. I hope that one day Haku and Sen's pure love will bring them together again. However, everything is the truth of life, found in the human world or the spirit.
