Lambdadelta takes over as Game Master following Beatrice's defeat at the end of the previous arc while Bernkastel takes primary control of the human side in the game. Battler meanwhile tries to understand the truth behind Beato's games and comes into conflict with Erika Furudo, a detective character created by Bern who approaches the island murders from a "mystery" perspective, in contrast to Battler's "anti-fantasy" stance. The chapter also has a focus on Natsuhi, who receives threatening phone calls from a "Man from 19 Years Ago".

October 4 and 5, 1986. The Ushiromiya family has gathered on the private island of Rokkenjima for their annual family conference. Chief on the agenda concerns the struggle for the inheritance assets of the ailing family head, Kinzo. But as the family is trapped on the island by a typhoon, they receive a letter claiming to be from the rumored witch of the island, Beatrice, and mysterious events begin to occur.

After recently moving to the rural village called Hinamizawa, Maebara Keiichi joins a club and makes new friends. He soon learns about the village's dark secret, Oyashiro-sama's curse, where one person dies, and one person disappears every year, and he also learns that his friends might be behind it...

In Tatarigoroshi-hen, Keiichi and Satoko develop a brother-sister relationship so when Satoko's abusive uncle returns to Hinamizawa, Keiichi attempts to help Satoko with drastic measures. However, as more and more people die, it is clear he is not the only one involved. This time, the spotlight shines on Satoko Houjou as being the "victim". Keiichi Maebara's passion to protect Satoko turns him into an unknowing villain in this chapter.

By this chapter, the reader should have an overall idea of how life in Hinamizawa is like. Once again, this chapter begins innocently, with the Watanagashi Festival again marking the start of the sinister events in Hinamizawa. An ancient curse strikes, and a pair of sisters are not what they seem. Shion Sonozaki makes her first appearance in this chapter, while Mion Sonozaki is portrayed as the villain.

Tsumiboroshi-hen is the answer arc corresponding to Onikakushi-hen. Unlike Meakashi-hen, Tsumihoroboshi-hen's story is drastically different from the plot of its question arc. In Tsumihoroboshi-hen, Rena experiences a situation similar to Keiichi's in Onikakushi-hen, as she makes a terrible mistake and becomes distrustful of her former friends. It is the first chapter with a (seemingly) happy ending, although the Tips reveal a sinister twist.

Meakashi-hen is the answer arc corresponding to Watanagashi-hen. Meakashi-hen consists of events very similar to those of Watanagashi-hen told from the perspective of Shion Sonozaki, with only a few minor variations. In this chapter, the audience sees the true reason for the criminal's murderous actions in Watanagashi-hen—a lost love. Satoshi Houjou is first physically met in this arc, unlike the others where he is only mentioned. The first hints of that which ties together the arcs are given.

On the surface, Minagoroshi-hen is the solution to Tatarigoroshi-hen; however, it answers most of the major common mysteries of the previous arcs. It is told from the perspective of Rika Furude. Most notably, the true identity of the murderer is finally revealed in Minagoroshi-hen. After Minagoroshi-hen, one more effort is needed to seal the story into a happy ending. (Source: Wikipedia)

A compilation of additional tips written by Ryukishi07 outside of the games. Several of the stories are humorous in tone, but the more serious ones may be considered canon.

Himatsubushi-hen takes place five years before the previous three. In contrast to the first three chapters, this chapter is shown through the eyes of Mamoru Akasaka, a young police investigator from Tokyo who comes to Hinamizawa in order to investigate a kidnapping of a politician's grandchild. Soon, he too becomes implicated in the mysteries of Hinamizawa. This chapter focuses on Rika Furude as being the key part of the mystery.

In Minagoroshi-hen, the mastermind of the murders was revealed. This time, all the pieces of the puzzle are in place. The last step for the characters to take is putting the pieces together in order to defeat the culprit, obtain the miracle, and break through the barrier of June 1983. Matsuribayashi-hen is a "Good End" in which no major deaths occur in that June, although the deaths in previous years still occurred.
