Summer Time Rendering: Season 1

Shinpei has a dream of childhood friend Ushio telling him to protect her sister Mio. As he awakens on the ferry he accidentally falls into a woman's breasts. Shinpei is traveling home to Hitogashima Island for Ushio's funeral. Sou, another friend, reveals Ushio drowned saving young girl Shiori. That night Mio is seen outside, staring vacantly until a relative named Tetsu, Hitogashima's only police officer, comes along. Sou tells Shinpei that marks on Ushio's neck suggest she was strangled, and y

Shinpei convinces himself it was a nightmare. However, upon arriving at the island he finds the day plays out exactly like before and notices the sound of a camera at Ushio's funeral. This time Shinpei is present when Mio stares vacantly at the house, and when Tetsu arrives he sees her murder Tetsu, causing him to realize she is Shadow Mio, and she replaces Tetsu's corpse with a Shadow Tetsu. The sound of the camera is actually the Shadow's disintegrating their victim's body into dust. Shinpei i

Mio decides they should save Shiori. At Shiori's home, Shinpei finds dust piles proving Shiori's parents were killed after the funeral, and that Shiori who attended the funeral was Shadow Shiori, suggesting Shiori had been killed before Shinpei arrived on the island. He attempts to trace the woman from the ferry but is unsuccessful. Tetsu, having been away on Shinpei's fake police report, isn't killed and so Shiori's disappearance is investigated properly and a detective is invited from the main

Ushio is convinced she is alive again and can remember that she died wanting to tell Shinpei she loved him. Shinpei suspects she is a shadow that actually believes she is Ushio. Ushio insists on seeing her friends and family but Shinpei angrily refuses. Mio calls Shinpei's phone, which Ushio answers before he can stop her, forcing him to lie to Mio. Forcing Ushio to stay hidden Shinpei meets Mio at the shrine where Sou suddenly confesses his love to Mio, though Mio rejects him. Ushio reveals her

Shadow-Mio disappears and the woman introduces herself as Nagumo Ryuunosuke who is there to save him. She reveals how to tell Shadows apart from humans; since their true form is the shadow flat on the ground and not the fake body above it. Shinpei rushes to the shrine and finds everyone killed by a Giant-Shadow. Giant-Shadow identifies Shinpei's eye as the eye of their Mother, which controls time. Shadow-Ushio still insists she is human and rejects her fellow Shadows. Mio is disintegrated. Giant

On this rewind it is revealed Nagumo reached the island already aware of the Shadows presence. The island priest, Karikiri Masahito, greets her at the funeral as Minakata Hizuru, revealing she grew up on the island. Shinpei, determined to do things right, uses Nagumo's trick for detecting Shadows and realizes at the funeral that Shiori and both her parents were already Shadows. Shinpei receives Nagumo's phone number in a code from Ushio's father Alan and solves it, but Nagumo had given her phone

Nagumo reveals to Shinpei that a Shadow murdered her family 14 years ago, causing her to leave the island and change her name, later publishing a series of books about the experience. Nezu reveals that if a Shadow who has copied someone is killed, that person can never be copied again. Nagumo goes to Shiori's home to kill Shadow-Shiori and her Shadow parents. Based on her behaviour, Shinpei suspects the trauma of losing her family caused Nagumo to develop two personalities, one being the sister

Surprised, Shinpei notes that Shadow-Ushio appeared much earlier than normal. She remembers the previous loop and wants to prevent all the deaths from Mother's resurrection. She hides from Mio in his room. As she eats, he pokes her shadow, which she feels, confirming she is a Shadow. He prepares to destroy her, but cannot bring himself to do it. She accidentally makes her clothes disappear, forcing her to wear his spare clothes, and finds that she cannot retreat into her shadow like the other Sh

The video shows Ushio and Shadow-Ushio as friends. Ushio was aware she would probably die soon and wanted Shinpei to know Shadow-Ushio is not evil. She explains the first Shadow was Shiori's with Shadow-Ushio appearing soon after. They tracked Shadow-Shiori to the island's old abandoned clinic once run by Sou's father Seido. There another Shadow attempted to copy Ushio and attacked Shadow-Ushio, injuring her by hitting her shadow and proving she was the copy. They killed the new Shadow then reco

Shinpei announces they need to head back to the old clinic. A police officer named Miura approaches Mio and her friend Tokiko to ask about Shiori's family. At the clinic Sou finds old bottles of Mercuric Chloride, a toxic medicine. He also discovers a wooden statue of Ebisu, God of Fishermen, but as this statue is female Shinpei realizes it actually depicts Ebisu when he was born as a leech like creature believed to be both male and female. They locate a secret door but no key. Shinpei realizes

Nezu and Nagumo prepare to enter the sewers. Shadow-Shiori appears to both Mio and Tetsu. As Shiori is technically a missing child Tetsu is forced to follow her. After killing the Shadow-babies Shinpei sees the cave is covered in coral and connects to the ocean. Ushio's arm grows noticeably worse and as the only way to heal it would be to copy Ushio again, which is impossible. To temporarily stop the pain she deletes her damaged arm. Tokiko suddenly appears. Nezu realizes the cave is the lost Hi

Tokiko explains that Haine is Hiruko and for generations their family has served her by feeding her dead bodies from their family clinic. Haine eats the body of Miura and almost eats Ushio's body, which was replaced with a fake before the cremation. Tokiko reveals she serves Haine because she promised to resurrect their dead mother once she regains her powers. Shinpei and Shadow-Ushio manage to steal Ushio's body which Shadow-Ushio scans, repairing her damaged arm. Shinpei tries to shoot Haine b

Shinpei and Ushio are looped back to the moment he revealed himself as a time traveler to Hizuru and Nezu. Hizuru realizes, that Shinpei's eye, which allows him to loop is made from Shadows and that Ushio granted him this power. They decide to work together to the end, to avoid failure, after which Ushio shows them her memories from previous loops. Sou attempts to talk to his father, but Seido brushes him off. Shinpei, Ushio, Hizuru and Nezu show up at the Kobayakawa household, expecting the sam

Shinpei and Ushio take a trip through Hizuru's memories as a high schooler, flashing in and out of on various encounters she had with Haine on the second floor of the Hishigata clinic. Hizuru and Haine gradually grow closer, owing to Hizuru's frequent trips to the clinic. On one of these trips, Hizuru runs into Nezu by chance, who is out snake-hunting. He warns Hizuru to find a less dangerous path to traverse, but she persists. This persistence leads to concern on the part of Ryuunosuke and Asak

Shinpei realizes what happened and concludes that it was a mistake to leave Nezu so far away. He also notices that the "event horizon" has caught up with him, so if he dies too soon, he will no longer be able to loop and they will lose. The group prepares to make their stand at the school, just as Haine, Shide and hundreds of Shadows boldly approach. Tokiko, Sou and Mio work together to defeat and capture Shadow-Mio, while Nezu and Hizuru/Ryuunosuke take down groups of Shadows. Haine and Shide c

Shinpei grills Shadow-Mio about her origins and abilities of Shadows. Shadow-Mio is resolute, that she is now on their side. Tokiko is furious, that Mio was copied, unbeknownst to her. The group chooses their next goal, to capture and interrogate Seido Hishigata. Finding the Hishigata household empty, they head for the clinic, where Tokiko leads them down to a secret entrance in the morgue, connected to Hiruko Cave. In the cave, they find the Shadow of Chitose Hishigata, strangling her husband.

Ushio tells Hizuru about the memories of child Hizuru they saw, theorizing that the section of Haine that broke off when she devoured Ryuunosuke is what became Ushio today. Ushio is afraid that she'll turn evil like Haine did, but Hizuru promises to kill her if it happens. Mio and Shadow-Mio have a heart-to-heart, where the latter reveals that they hate themselves, for not being more like Ushio. Seido tells Sou, that their mother actually passed years ago. Tokiko soothes Shinpei, telling him to

Shinpei and Ushio sit down to talk with Karikiri, while the others listen in. After some pleasantries, Shinpei holds him at gunpoint and tosses him photos of himself from decades ago, revealing that Seido has told him, that Karikiri is actually Shidehiko Hishigata, founder of the Hishigata clan, husband to the original Haine, when Hiruko came to the island and copied her and that he is actually a human-Shadow hybrid progeny who maintains his youth by having his memories and personality copied an

Haine summons Shadows to attack Shinpei and the kids. However, as Shinpei reaches for Ushio's seashell necklace in his pocket, Haine is startled and the Shadows retreat. Shinpei tries calling the others, but there is no service in the mountains. In the meantime, Haine uses the guise of Shinpei to call Hizuru's group to the small northern island of Torajima. Shinpei realizes that Haine has copied him in the third loop and now uses that guise in the current eighth loop, when he hears from Alan tha

Hizuru is able to discern from memories of past loops, that Shide's goals might be different from Haine's and tries to pit them against each other. Ryuunosuke is able to disarm Shide, after which Hizuru transfers his data directly into Shide's armor, which is composed of empty Shadows, allowing Ryuunosuke to take control of the armor and create his own body. However, without Ryuunosuke holding her up, Hizuru's muscles and bones receive irreparable damage, forcing Tokiko to jump in with her Shado

As Shinpei mourns Hizuru on the beach, Seido informs him about the whereabouts of her corpse. Shinpei insists that the cause of death should be ruled as murder and they begin theorizing about the existence of the second Shide. To Seido's surprise, Shinpei predicts a lightning strike. Shadow-Mio helps Shinpei realize why Haine and Shide were scared of the seashell necklace, as Ushio stored her memories and what she scanned of Shide in it before dying. As such, Shinpei has an epiphany, that the or

Shide notices that his armor and the Shadows attacked by Ushio are not regenerating, so he realizes that Ushio can erase Shadows just by touch now. After noticing the injuries Shinpei sustained from Ryuunosuke using his body, she lunges at Shide. Shadow-Mio, who was disguised as Shinpei's watch, stops her and shares the plan with her. Haine, using Shinpei's guise, tries to determine his plan, before telling Shide to stop Shinpei from shooting himself. Thanks to the two-second foresight of Ryuuno

The third Shide emerges with the mortally wounded Haine, reduced to a toddler form. He berates Haine, now useless to his goal. Shinpei voices his disgust of Shide, who promptly slices Haine's shadow open, revealing an entrance to the timeless world of Shadows. As he jumps in with what remains of Haine, Shinpei and Ushio follow suit, resolved to prevent his end goal. Shinpei awakens in the timeless world, separated from Ushio. Ryuunosuke takes control of his body to alleviate his pain and they bo

Ryuunosuke grabs Ushio from the sky, and Haine remarks that Ushio's body is in severe shape and she cannot fight anymore. Shinpei proposes that Ryuunosuke possess Shide's armor. Having gained telepathy akin to Hiruko, Ushio tells Shinpei and Ryuunosuke that she can turn herself into shotgun shells which would hack away the armor, but she needs time. Shide is shocked at Haine's betrayal, lunging at them. Ryuunosuke, using Shinpei's body, is able to fight on even terms with Shide for a while, usin

Now in a timeline where Shadows no longer inhabit the world at the present day, Shinpei awakes on the boat with Hizuru, blurting out her real identity, but no longer remembering where he learned it from or why he was so concerned about her well being. Mio, Tokiko and Sou greet him on the pier, where he realizes he came back because Ushio called him a day before. As they begin walking home, they run into Ushio who attempts to punch Shinpei, since she is still angry about him leaving two years ago
