## Plot

Yuta Gamon, a self-proclaimed NEET and owner of the paranormal blog Kirikiri Basara, unexpectedly becomes entangled in a supernatural conspiracy tied to the mysterious "256 Incident." This event, involving the mass suicide of 256 people by drowning at Inokashira Park, triggers a series of bizarre occurrences in Kichijoji. Yuta and his eccentric group of acquaintances—including his bubbly friend Ryoka Narusawa, investigative journalist Toko Sumikaze, introverted doujin author Ririka Nishizono, ESP-researcher Sarai Hashigami, high school fortune teller Miyuu Aikawa, medium Aria Kurenaino, and detective Shun Moritsuka—become embroiled in the mystery after encountering strange phenomena and a cryptic coded list tied to the victims. This list was left behind by Sarai's father, Professor Isayuki Hashigami, a physicist investigating the occult and supernatural, who had recently theorized the possibility of ghosts existing. Hashigami’s brutal murder was predicted three days beforehand during a public internet livestream by Miyuu.
As the group investigates these incidents, they uncover ties to a secret organization called the Society of Eight Gods of Fortune. (Hachifuku-shin Circle) This shadowy society has been conducting clandestine experiments blending science and the occult. Using advanced technology, they manipulate electromagnetic frequencies and even use chemical injections of scandium to control people’s perceptions and actions . These methods allowed the Society to orchestrate the mass suicide at Inokashira Park, making ordinary people kill themselves without understanding why. The end goal of the Society’s project is the implementation of a so-called “World System”, a network intended to synchronize the physical world with the spirit realm, effectively erasing the boundary between life and death. In pursuit of what they see as a form of immortality, the Society plans to use this system to freely move souls between planes of existence. The investigation also reveals a critical piece of hardware: “Odd Eye,” a large antenna array in Kichijoji that broadcasts the Society’s mind-control signals. This device is the final linchpin in their plan for world domination via the World System, posing a grave threat to reality if not stopped.
Before long, Yuta and his friends make a chilling discovery: they themselves were victims of the 256 Incident and have been dead without realizing it. Their bodies were among those recovered from the lake, and the group has been operating as astral bodies (ghosts) ever since the mass drowning. Existing in this liminal state of suspended death, they appear alive to each other but cannot be perceived by ordinary people. This explains various phenomena they experienced and why some clues (like the coded victim list) were accessible only to them. They also learn that time flows at a vastly different rate for the astral plane: roughly one day in ghost form equals only one minute in the physical world. This time dilation means that although they have experienced days of activity since the Incident, only minutes have passed in the real world. The realization of their ghostly status tests the resolve of the group. Additionally, Yuta learns that Ryoka Narusawa is not an ordinary girl at all – she is actually Aveline Tesla, a spirit medium (or “spirit guide”) who has been covertly guiding and protecting him. Ryoka/Aveline had been communicating cryptically (under the nickname “Zonko”) and is linked to the Society’s experiments, yet she chooses to help Yuta’s group after growing attached to them. With her insider knowledge and the late Professor Hashigami’s research, the protagonists piece together how the Society’s technology works and how they might reverse its effects.
With the Society of Eight Gods’ plan nearing completion, Yuta and his friends confront the organization at the Odd Eye antenna facility. In a final showdown, they use Tesla-inspired devices – including Yuta’s father’s custom radio (nicknamed the “Skysensor”) and an unlocked form of Yuta’s toy Poya-Gun (revealed to be the potent Wardenclyffe Gun) – to disrupt the Society’s signal. During the battle, Yuta heroically sacrifices himself to destroy the Odd Eye antenna, overloading it with energy from the Wardenclyffe Gun and Skysensor. This blast of energy severs the link between the physical and astral realms. As a result, the souls of Yuta’s friends are forcibly propelled back in time to re-enter their bodies at the moment of the drowning. Thanks to the astral time dilation, only about nine minutes have elapsed in the real world since their deaths. This brief gap means their bodies are not yet beyond saving – the group awakens back in the lake just after the suicide incident, and each person manages to swim ashore or get rescued before permanent death occurs. In effect, they are revived: the 256 Incident is partly undone for them, and they return to life with full memory of the ordeal. This timely resurrection thwarts the Society’s ambitions, dismantling the World System and preventing the collapse of the boundary between life and death. However, Yuta’s fate is bittersweet. Having expended his energy to ensure the others’ revival, he remains behind as an astral being, unable to revive his own body. In the aftermath, Yuta’s friends mourn his loss yet carry on living, thanks to his sacrifice. The ending implies that Yuta finds peace in the spirit realm – he reunites with his late father there – and continues watching over the living world as a guardian spirit. The occult conspiracy is brought to light and halted, and the once disparate group of nine lives on, forever bound by their extraordinary experience of life, death, and second chances.

Conspiracies about the incident being caused by mass hypnotism abound, which Yuta refutes, pushing instead for the theory that the deaths were a result of a suicide volunteer offline meeting. Returning home, Yuta does research on the death of Professor Hashigami, which led him back to Kiri Kiri Basara where he once made a post regarding the late professor. In the comments, he noticed a post made by Shun, which pointed him to a dojin drawn by Ririka, titled "A Dark Water's Bottom".
