Okami-san and Snow White, Who Is Immune to Poison Apples

Ringo is having trouble confronting her friend Himeno Shirayuki, who looks after seven siblings. When Ryōshi inquires the matter, Ringo explains that three years earlier, when she first became friends with Himeno, she discovered that she was actually her half-sister, and that Ringo's mother had taken over her house. Since then, Ringo had become unable to bring herself to talk to her. The next day, the Otogi Bank, along with Himeno and her siblings, go to a swimming pool, with Ringo continuing to hide from Himeno. When Himeno almost drowns trying to rescue one of her siblings, Ringo saves her using CPR, and the two finally have their long awaited reunion. The next day, Ringo convinces the school director, Ranpu Aragami, to give Himeno a special scholarship.
