Okazaki Shino

Shino is Tomoya's grandmother on his father's side. She only appears in the After Story portion of the plot. During Ushio's path, when Ushio is finding her toy robot she lost in the flower field, Tomoya meets Shino at the edge of the cape, who introduces herself to him and their meeting is planned by Sanae. Shino tells the story about Naoyuki's past and tragedy after Atsuko's death, which is similar to what Tomoya is facing after Nagisa's death, along with his sacrifices made for Tomoya just to see him grow up to be a proper man.
