Episode Description:
On this rewind it is revealed Nagumo reached the island already aware of the Shadows presence. The island priest, Karakiri 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 to her contact on the island, Nezu Ginjirou, who answers the phone. To test if Shinpei is human, Nezu shoots Shinpei's shadow, proving he is human. Meanwhile Nagumo does the same on Alan in the bathroom and in a surprise attack smashes his shadow with a hammer, killing Shadow-Alan instantly. Shinpei meets Nezu who now trusts him and introduces him to Nagumo. Using coded references Shinpei is able to communicate certain facts to Nagumo so that she instantly knows Shinpei is a time traveler who has met her before in the future and is someone her future-self trusted. Shinpei cries as he finally has an ally who knows everything.
