Plot[]
1st Loop[]
After two years away, Shinpei Ajiro returns to Hitogashima to attend the funeral of his childhood friend Ushio. Stepping on the island, Mio welcomes him, and they head towards the funeral while chatting about various subjects.
The next day, Shinpei and Mio work at Kofune's dinner. The police officer, Tetsu, explains that the whole Kobayakawa family had vanished. Hearing that, Mio runs away, and Shinpei follows her. After catching up to her, Mio explains that Shiori said she saw a girl looking like her about a week before the incident with Ushio. An old hunter, Ginjiro Nezu, tells them that it's a shadow, and those afflicted by shadow sickness see their shadow and then get killed by it. The shadow then acts as the dead person and kills the remaining family. It was a common sickness before the war, and those afflicted went to the Hito shrine for cleansing. Mio then states she saw Ushio's shadow along with Ushio three days before Ushio died. Shinpei then decides to go to the shrine to learn more about the shadows. However, the shrine is closed, and Mio sees Shiori in the forest, and they run after her. They are unable to find Shiori but hear a gunshot, and following the sound, they see the woman with glasses bleeding from a gunshot. Mio heads to get help, and the woman tries to tell Shinpei something but gets shot in the head. Shinpei then sees another Mio holding a gun and holding the original Mio hostage. The other Mio then shoots Mio and Shinpei.
3rd Loop[]
On his third time stepping on Hitogashima, Shinpei manages to stop Mio from falling into the water, but he ends up falling into it, and she jumps to save him. That evening, he records the Shadow Mio outside of their house and, in the morning, shows Mio the footage, explaining it's a Shadow that came to kill her. As he is aware of Ushio seeing her shadow, Mio guesses that Ushio told him that, and Mio then realizes that Ushio was likely killed by her Shadow. Mio tells him that Shiori also saw her shadow, but Shinpei decides to go alone.
Later, Shinpei returns to Kofune's Diner, and moments later, Tetsu comes, explaining that the Kobayakawa family is gone. As Sou comes, Shinpei tells them about everything, and Mio suggests they visit the priest as he may know something. The group then decided to go during the Summer Festival tomorrow. The next day, they go to the festival, but before meeting the priest, Shinpei sees something and runs, leaving them. When the fireworks stop, Mio calls Shinpei but hears Ushio. She is shocked, but Shinpei explains she is imagining it. Mio then tells him to come to the shrine, and soon Shinpei returns to them. Sou uses the chance and confesses to Mio, but as Mio loves Shinpei, she tells Sou she just wants to befriend him. Ushio then appears and comforts Sou, but everyone sees through her disguise. Mio doesn't believe that's Ushio and calls her a monster, warning Shinpei to stay away from her. Still, Shinpei refuses and grabs Ushio, wondering what she was thinking about trying to switch places with someone who had a public funeral. The group then realizes that Shinpei is a shadow. Other shadows come, and they start killing people. Shadow Sou attempts to kill Sou, but Sou uses his body to protect Mio. The real Shinpei then arrives, and they try to reach each other, but she is consumed by the shadow in the end.
4th Loop[]
On the fourth time at the funeral, Shinpei asks Mio if she wore white panties yesterday. He recalls that Shadow Mio had white panties, but today, Mio is wearing a different colour. Mio finds the question weird but answers it anyway after Shinpei reveals the reasons.
At home, Mio decided to cook to make Shinpei feel better. As he finds her doing it, he takes over and tells her to wash herself. When Mio returns, she hears his stomach rumble and relaxes as she guesses that she is okay. Shinpei goes to eat in his room and takes two plates. Later, Mio comes to take the plates but is surprised he ate from two spoons and used two glasses, guessing that Ushio visited and explaining that in Hitogashima, they believe that the soul of the dead returns to their home and protects the family as their deity. She ends up spending the night talking to Tokiko on the phone and, in the morning, gives the shell necklace to Shinpei.
Mio and Tokiko are hiding from the rain. Tokiko wonders if Mio will attend the festival tomorrow, but Mio explains she doesn't have a yukata. Tokiko states she will gladly lend her one. Tokiko then wants a favor from Mio and asks her to stay with her tomorrow. A man then shows up, but seeing he isn't local, Tokiko wonders who he is. The man introduces himself as Miura from Wakayama's northern station and asks them if they know the Kobayakawas.
Mio tries to call Shinpei and Sou, but they don't pick up their phones. She sees Shiori, who whispers that Shinpei is that way. Heading to the corner of the street, Mio encounters Tetsu Totsumura, and they see Shiori pointing at a manhole, which is slightly opened. Tetsu doesn't want to go there as he will stink and Erika won't like him, but Mio states that if he finds the missing girl, he will be a hero, and girls will be all over him. That convinces Tetsu, who then leads them into the sewers. Following the sewers, Tetsu starts to complain, but Mio tells him he will tell Erika how brave he is, so he decides to continue. They reach a dead end, but Shiori flashes and eats the iron bars, allowing them to proceed. She is then captured by the shadow parent, who brings her to Heine and uses her as a hostage to make the others obey. When the shadow no longer needs her, he crushes her skull and kills her in front of Shinpei.
6th Loop[]
Mio and Shinpei's friends are called to the elementary school. There, Ushio shows them her memory of the previous loops. Mio apologizes for calling Ushio a monster, but Ushio plays it cool. Shinpei asks them to help him fight the shadows, and Mio agrees.
7th Loop[]
Mio and Ushio find Shinpei at home and explain that he was taken out by a sniper rifle. Shinpei explains first to them and then to everyone else that he can only loop one more time as the time limit for the loop moves faster after each death.
When Heine and Shide come with shadows, and they case Shinpei and Ushio, Heine orders shadow Mio to take out Ginjiro. However, Mio, Sou and Tokiko remain to protect him and fight Mio. Eventually, they defeat her, pin her with the nailgun, and later ask Ushio to turn her into one of them.
As Shadow Mio is turned into an ally, Shinpei questions her and learns that shadows like her can produce only one shadow and that shadow cannot produce more shadows. If the shadows don't erase the copied human within a week, they become mud. Since Seido Hishigata may know Heine's plan, Shinpei decides to visit him. Before leaving, Shinpei asks Shadow Mio to protect Mio. Shinpei reveals she is afraid and doesn't fully trust Shadow Mio, but she explains she hasn't killed anyone yet in this timeline. She asks Shinpei if he has a girlfriend, but he denies it. Shadow Mio wonders if he wondered why she never called him "big brother", but at that moment, the rest of the group comes, and Mio pushes Shinpei to go.
Later, when the group finds Seido and teams up with him outside the house, Shadow Mio talks with Mio and reveals that Mio hates everything about herself as she is the opposite of Ushio. Shadow Mio tells her that she must tell Shinpei how she feels or she will do it, but the true Mio refuses, stating she can't do it. The next day, when Shinpei is leaving with Ushio to find and kill shadows, Mio tells him that there is something she wants to talk about when he returns.
8th Loop[]
Mio and Sou receive a call from Shinpei, informing them that Ushio is dead and tells them to meet him at Alain's garden. Thinking that Ushio's hack could be undone, Mio pins shadow Mio and leaves. Mio and Sou then head to the garden, where they meet Masahito, who turns into Shide. Sou and Mio are captured by Masahito and then sent to Haine, where she eats them.
9th Loop[]
Mio and Sou are heading towards Alain's garden, but Shinpei and Shadow Mio exit the sewers and stop them. Shinpei wonders if her phone is turned off, and Mio confirms since he told her that a shadow may contact them. Shadow Mio tells her that it has already happened, making Mio realize the previous call was from a shadow Shinpei. Mio apologizes to Shadow Mio for pinning her, but Shadow Mio is okay with it and has scanned Mio to heal her wounds. Shinpei then tells Sou and Mio to return to Kofune's and protect the kids.
Sou recalls the pseudo-loops that Ushio showed them and that he confessed to Mio, and she turned him down. He wonders if Mio also remembers that. Mio then shows up looking for Shinpei and Sou tries asking her again, but Mio acts like she is the shadow Mio and states nothing changed. Sou then says she likes Shinpei, and Mio starts to panic and blush, making him express she ain't the shadow, but confirms that her feelings for Sou and Shinpei have not changed. Sou then states that Shinpei said he would be on the roof.
Mio then meets Shinpei on the roof and asks if Ushio will really be coming back, and Shinpei believes so. Mio confesses that she loves Shinpei, who feels awkward and thanks her. Mio realizes he knows, and he confirms. Mio explains she wanted to say it as there is a chance they all die tomorrow. Shinpei apologizes and states he can't return her feelings as he loves Ushio, and Mio is his little sister. Mio is happy to have let it out of her chest, but as she returns to her room, she cries over Tokiko's shoulder. Shadow Mio states that if they defeat Haine, Ushio will be gone and if Mio asks if she will have a chance, then. However, Mio couldn't ask that and knows that Shinpei isn't a playboy.
11th Loop[]
Hiruko and the Shadows do not exist in this conclusive loop.
Mio and the rest meet up with Shinpei as he arrives at Hitogashima. On the 24th, they go to the festival, where Sou confesses his feelings to Mio, and she asks him what he likes about her.
