Tokiwa

The protagonist's double in the second timeline. He's everything the protagonist used to be, including being the partner of Tsugumi, much to the protagonist's dismay. ~!Nearing the end of the story, he confronts the protagonist's stalking tendencies, and instead of being mad he gives him a full schedule of his future activities, including driving to a diner with Tsugumi.
