Much of the episode’s first half takes place through the eyes of Nagumo Ryuunosuke, AKA Minakata Hizuru. When she watches Mio send herself and Shin into the sea, and wonders if this “Shin” is Ajiro Shinpei. She attends the funeral, meets old friends, and we learn she frequented the Kofune diner as a middle schooler, before Shinpei was taken in by Alan. She was also friends with Shiori’s mother Asako, whom she learns is a Shadow when her shadow moves to avoid Hizuru’s feet.
Hizuru can’t trust anyone on this island…anyone, that is, except Nezu, whom she seems to trust implicitly. Not only does she invert herself in his presence, she even cries. She uses Nezu as a sounding board, reporting that the entire Kobayakawa family has been killed and replaced by Shadows, and that Ushio drowned because a Shadow attacked her. There’s a Shadow that can make other Shadows, and it’s been busy. How Hizuru and Nezu intend to end its free reign remains to be seen.
That brings us to Shinpei, who tries to act normally, but still warns Shiori about Shadows, inviting the suspicion of her parents. In one of the creepier moments in an episode full of creepy moments (what with all the body-snatching) and ant creates and ant-sized hole as it crawls across Shiroi’s parents’ shadows. Then Alan gives Shinpei a note written in a seemingly indecipherable code…unless you happen to be a fan of Nagumi-sensei’s work.
We see Shadow Mio create a Shadow Alan, who tries to replace the real Alan when he goes to the bathroom. However, Hizuru is already waiting for it, and smashes Shadow Alan’s shadow with a sledgehammer, thus destroying it. But it’s a hollow victory; so many lives have been taken already, and so many more hang in the balance. Hizuru and Nezu wont’ be enough … especially if neither of them can travel through time.
Enter Shinpei, who cracks the code and calls the number for Hizuru’s second phone, which she gave to Nezu. Nezu makes sure Shinpei isn’t a Shadow by getting him to stand in a certain place, then shoots his shadow with his sniper rifle. Once that’s settled, he takes him to Hizuru, and Shinpei immediately asks for Nagumo-sensei’s autograph.
Of course, Hizuru knows for a fact that no one but Nezu knows that she’s Nagumi-sensei, which means the only way Shinpei knows is because he’s lived July 22nd before, likely multiple times. When she tells Shinpei this, he can’t help but tear up in relief: somebody knows and believeswhat’s happening to him. Someone who can help him save Mio and the island.
