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.

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.
