みずさわ ふみお grand prize and readers' prize

A fine arts student named Wataru Doiguchi applies for a lacquer-tapping part-time job at a remote village. Recruited by a local woman named Yoshie, he travels to the settlement, only to find upon arrival that Yoshie has already died. The village headman asks Wataru to perform a peculiar ritual called "Hatsugami-oroshi" — an ancient rite in which the hair of a deceased woman is let down to guide her soul to the afterlife. Over the few days before the ceremony, dark secrets about the village and Yoshie surface, and Wataru realises he must find a way to survive the trap set by vengeful spirits.

A terrifying ritual to let down the hair of the dead and guide her soul — a story of dread and survival for one young man drawn into an ancient village ceremony.

The being before me is a true demon. What is terrifying is that even knowing this, I find myself drawn to it irresistibly.

Psychiatrist Kamimori Chisato faces the successive suspicious deaths of patients who complained of seeing a "dream that leads to death." The nightmare begins to "infect" her as well, as she starts dreaming of attending a mysterious ritual. Meanwhile, occult writer Ito Sota, chasing the urban legend of the "cursed dream," discovers the existence of a strange ceremonial rite on a remote island from a deceased colleague's note reading "the key is Yumemōde." When the two investigation threads converge on the island's cursed folk customs, the "order of death" closes in. Winner of the Readers' Award at the 45th Yokomizo Seishi Mystery & Horror Grand Award. Published under the title Yumemōde, revised and retitled from the original submission title "Yume ni Sumitsuku Mono."

See that nightmare, and you die -- find the key to breaking the curse before your turn comes.

綿原芹 わたはら せり Kakuyomu Award

A linked short story collection set against the backdrop of mermaid legends in a fishing town in Wakasa. The work depicts the grotesque entanglement between mermaids and humans surrounding "overwhelming beauty." It follows the tragedy of a girl who gains supernatural beauty by drinking mermaid blood, and the humans undone by her existence, weaving together themes of lookism and obsession with beauty. Judge Yukito Ayatsuji praised it as showing "a fine sense of mystery—and it is frightening," while Honobu Yonezawa declared "this novel has depth and sorrow."

"What stands before me is a true demon. What terrifies me is that, even knowing this, I feel an irresistible fascination."
