遥かなる円形世界

-Rewrite the world.-

Months after the incident on Shironagasu Island —

In two cities — New York and a rural town in Japan — two stories begin to unfold. A detective and a girl. Their stories were never meant to intersect — until a forbidden device that rewinds time binds them together. To reach the truth, they repeat, again and again — even if it means losing everything...

Through the Zapping System, two stories progress simultaneously — and the way they intertwine drives the narrative forward.

A suspense x sci-fi x mystery adventure set across New York and a provincial Japanese city, where the stories of two protagonists collide.

[Side A — New York Arc]

Brooklyn, New York. A mysterious figure named Lila stumbles into the office of private detective Ikeda Sen. Around the same time, a client named Walton entrusts him with an enigmatic device.

Soon, the illicit organization "Babylon" emerges in pursuit of Lila, and its operative Callander stands in Ikeda's way. With NYPD detective Tio, assistant Koi, and heiress Akira — a group of eccentric allies — Ikeda plunges into the heart of a massive conspiracy.

[Side B — Japan Arc]

A provincial city in Japan. High schooler Izumozaki Neneko lives a quiet life, hiding a special ability — perfect memory. Her everyday world is shattered when skeletal remains are found in the canal along her school route.

Mysterious traces left beside the body, the shadow of her mother who vanished months ago, and an unsettling presence creeping closer to those around her. Together with her sister Kisara, and friends Niwa and Torako, Neneko pursues the truth — which links to past incidents and reveals three suspects.
