Ryuka Mami no Kiyu Cover and Announcement

Ryuka Mami no Kiyu Returns as a Four-Volume Digital Release

On November 10, 2026, the official Ryuka Mami no Kiyu promotional account announced that Saki Okuse's manga would return through a new digital publication.

The edition is planned as four volumes under Taiyoh Tosho's Emperors Comics imprint. Volume 1 is scheduled for December 2, 2026, with the remaining release dates still to be confirmed.

According to the publisher-provided retail description, the digital edition features additional material and editorial revisions. This is not an entirely new storyline but a reissued version of a work previously published in collected print volumes.

BOOK☆WALKER has opened preorders for the first volume at 770 yen, allowing readers to reserve the electronic edition ahead of its release.

Ryuka Mami and the Mysterious Girl from Odawara

Ryuka Mami no Kiyu follows Ryuka Mami, an elegant woman working as a spiritual medium known as a kuchiyoseya. She lives in a property associated with an unusual history and drives a car that was previously involved in an accident.

Mami possesses the ability to hear the whispers of ghosts and witness memories left behind by spirits. This power draws her into supernatural incidents that remain connected to the human world.

One rainy day, Mami discovers a girl named 來夕 sheltering beneath an elevated road near Odawara Station. Their encounter begins a series of mysterious experiences involving the supernatural.

The relationship between the two characters becomes part of the story as Mami's unusual abilities expose memories connected to events surrounding them.

Investigating a Mysterious Death Near Tama River

An early case introduces Tenme Shibaro, an insurance investigator who requests Mami's assistance with a suspicious death.

Mami becomes involved in the investigation alongside the girl she encountered in Odawara. The clues lead them to the middle reaches of Tama River, where the memories of a ghost begin resurfacing from beneath the water.

The manga uses Mami's spiritual abilities to uncover events from the past that ordinary investigative methods cannot explain. Its mystery develops around the connections between living people, ghosts, and lingering memories.

The publisher's synopsis does not disclose the victim's identity, the cause of death, or the investigation's outcome. Those details remain part of the narrative itself.

Continuing Saki Okuse's Teizoku Reigari Universe

Ryuka Mami originally appeared in Teizoku Reigari (低俗霊狩り), Saki Okuse's supernatural horror-comedy manga.

In that series, Mami works as a spirit hunter specializing in lower-ranking supernatural entities, including animal spirits. The wider franchise later expanded through related titles such as Teizoku Rei Daydream and Teizoku Rei Monophobia.

Ryuka Mami no Kiyu continues the character's adventures with greater emphasis on ghostly memories, encounters with new characters, and mysterious deaths.

The work previously received three collected volumes through Wani Books between 2017 and 2019. The upcoming electronic edition introduces another publication format through Taiyoh Tosho, featuring revised content compared with the earlier release.

Why This Matters

1) An older supernatural manga returns digitally

The Taiyoh Tosho release provides another way to access Ryuka Mami no Kiyu through a revised electronic edition, giving readers a new opportunity to explore Okuse's supernatural mystery.

2) Ghostly memories drive the investigation

Rather than focusing entirely on exorcism battles, Mami's abilities help reconstruct incidents from the past. This approach connects supernatural horror with a more investigative form of storytelling.

3) The Teizoku Reigari follow-up is planned across four volumes

The four-volume plan establishes the intended scope of the new digital release. The individual schedules for later volumes, however, still require confirmation from the publisher.
