After Suguru's water heater breaks, Ms. Shikijo and Mahoro's rivalry explodes during a visit to a Bath House where Miyuki's family works. July 19th, and school has ended. July 20th marks the day that Suguru's father has passed away. In memory of his passing, Suguru asks Mahoro to accompany him to the gravesite, not knowing that Mr. Misato had once worked for Vesper and served as Mahoro's superior in this secret organization. Not only does Suguru feel the loss of his father, but Mahoro, equally, if not more so is torn at the loss of Suguru's father for reasons that only she knows.
