Synopsis[]
Seiko is requested by Turbo Granny for additional food and responds that the cost of food is high because of the influential figures in Japan. When Turbo Granny threatens to leave if her demands aren't met, Seiko casually tells her to go ahead. Frustrated, Turbo Granny departs with her cat, later resting outside and thinking that Seiko might already be missing her. As snow begins to fall, Turbo Granny keeps her cat warm and urges it to return to the Ayase residence where it will be safer. Seiko eventually finds them, assuming Turbo Granny had given her portion to the cat. She then shows her a bag of cat food she brought, reminding Turbo Granny that cats should eat proper cat food rather than human food, and tells her to walk back home with her. While walking with her, Turbo Granny inquires if the food she brought was costly, to which Seiko responds affirmatively.
