1) The Sea Palace. Ginko pokes about for information on people who were reborn in a coastal community. A woman, Mio, with a daughter, Isana, tells him about a nearby trench called the Dragon Palace where if a person dies there, they can be reborn. Her daughter is in fact her mother, Mana, reborn, though she has raised her as her daughter alone. Ginko spends time investigating and determines that some little known mushi is at the bottom of this. Isana starts to display mannerisms and memories similar to her grandmother/first incarnation. A storm sweeps Isana out to sea and she and Ginko are nearly eaten by the strange mushi, so Ginko determines that it eats living creatures then releases something that can form a clone of those it has eaten. Since the people on the island work well with the mushi he leaves them alone. An interesting story and an intriguing scenario, though it seems really weird that the mushi would provide a way to clone its prey, especially when it would be so uncertain to happen; but I suppose it is the nature of mushi to do mysterious things. I kind of wish it were somehow not a mushi, just to break things up, especially since it is not at all a surprise when Ginko determines that a mushi is the cause.
Bonus Manga: A Tale of Quite a Long Time Ago, Sounds in the Mountain Chapter. A story the author's grandmother was told by her father. On a nearby mountain something called Atogo-sama was worshiped, though what it was is unknown. One day a great "doooom" sound came from the mountain (said to be the angry voice of Atogo-sama) and apparently drove an old lady mad. An interestingly mysterious story. I feel like it would have been better included in Volume 2 since it seems reminiscent of the kuchinawa from the story "The Mountain Sleeps".
2) Eye's Fortune, Eye's Misfortune. Ginko encounters Amane, a seemingly blind woman who plays a biwa and tells stories abut mushi. She tells him her own story, that her deceased father had been a mushishi and though she had been born blind, she gained sight after encountering a mushi called ganfuku. But more than just being able to see, her vision became excessively keen and she was even able to see the past and future of other people, though warning them of future problems never served to avert disaster. When her father died during his travels she took to traveling herself. She asks Ginko to bury her eyes in the mountains for she has finally had a vision of their future, and then things come to pass exactly as she had foreseen. Blind again she continues on her travels. I think the idea of excessively keen vision is an interesting one; I think I encountered a similar story somewhere else, the keenness of vision caused by a disease. Amane is another character I would like to encounter again, especially to see how she fares; she seems to scorn the vision she gained, but it would still be hard to give it up I would think. Also, fun continuity point, that Ginko sends out a message by uro-san to try to find help for her.
3) The Coat That Holds a Mountain. Ginko finds a haori with a beautiful painting of a mountain on its inner lining that occasionally has puffs of smoke appear. Combined with its unusual weight he determines there must be mushi in it and sets out to find the artist who painted it. The artist's story is told in flashbacks, that the haori was a gift from his elder sister before he left to apprentice as a painter. The painting was some of his first practice work, but he sold it for money for supplies when he was just starting out. He became a successful and moderately famous artist, but became too wrapped up in his work and lost contact with home. When he finally returned he found his father had died in a landslide and his sister had died in childbirth and he had failed to read the letters telling him of such. Devastated he took up living in his home village, though we was looked down on. He eventually adopts his nephew who is slow to develop. Ginko shows up and reveals that the mushi in the coat were ubusuna which were common i the region. Having returned home they left the coat. He gives advice to help the nephew develop faster and sells the coat back to the artist, but requests the creation of an identical copy which he sells to Adashino-sensei after leading him to believe that it also contains mushi like the original did.
4) Flames of the Fields. A strange new plant is spreading rapidly and poisoning other plants. The local mushishi, a young woman named Nohagi, decides that to save the village the plants must all be burned. Ginko cautions against it, but the fields are burned and the plants release mushi called hidane that are surrounded by kagebi, false flames that drain heat from people. Some people die or are injured from contact with the kagebi. Nohagi swallowed one and was slowly dying, but Ginko devices a method to save her. I moderately dislike this story since it is the one that makes it super obvious that Ginko just goes around saving otherwise helpless women from mushi infection; especially egregious since Nohagi is a competent mushishi in her own right.
5) The Snake of Dawn. A boy asks Ginko to help his mother who has been forgetting things more and more. Ginko determines that a mushi called a kagedama has entered her brain and is eating her memories, though it avoids memories that relate to daily life, things she reflects on. There is no cure except to have lots of different experiences so there are more unimportant memories for the mushi to eat. Inspired the woman sets out to find her husband who had been working as a traveling salesman, but they find that he had started a new family in another town. The mother becomes depressed and the mushi eats almost all of her memories, though she continues to be upbeat. This is an enjoyable story, but I am bothered a bit by how her memory loss is played for laughs, given that in real life it can be pretty devastating.
Bonus manga: the author writes a bit about hiking the ancient road of Kumano.
