Iwanako (岩魚子, Iwanako) is a former classmate of Hisao's at the school he attended before transferring to Yamaku Academy. She only appears once in the game (in the prologue), but is mentioned in throughout the story.
In the opening scene, Iwanako asks Hisao to meet her in a forest during winter. As she's asking Hisao to go out with her, a strange pounding occurs in his chest. He passes out and has the heart attack that sent him to Yamaku. Iwanako visits Hisao every day in the hospital for a month and a half. Hisao notes her to be the "last one to stop visiting" among his friends. However, when she was there, they barely spoke to one another.
While at Yamaku (regardless of route) Hisao receives a letter from Iwanako. It contains little but smalltalk, describing the school they once attended together and changes with the new term. At the end, she wonders if they will ever meet again, but maybe it's better if they don't and that he can write back to her if he wants.
How Hisao reacts and responds to the letter varies by route.
